I have enough information from the library and my medical knowledge to answer all questions comprehensively. Let me now provide complete answers for all questions across all three images.
Complete Answers with Reasons
IMAGE 1 (Page 1 - Questions 01-08)
Q01. Volkmann's Ischemic Contracture - sequel of which fracture?
Answer: (a) Supracondylar Fracture of the Humerus
Reason: Supracondylar fracture of the humerus is the most common cause of Volkmann's ischemic contracture, especially in children. The brachial artery runs anterior to the distal humerus and is at risk of injury or compression with this fracture. Prolonged ischemia of the forearm flexor muscles leads to fibrosis and contracture - the classic Volkmann's contracture. This is a well-recognized complication of this fracture and a key reason why it requires urgent reduction.
Q02. 23-year-old squash player with lateral epicondyle pain, pain on resisted extension of wrist
Answer: (d) Tennis Elbow (Lateral Epicondylitis)
Reason: The hallmark of lateral epicondylitis (tennis elbow) is:
- Pain at the lateral epicondyle
- Tenderness over the lateral epicondyle
- Pain reproduced on resisted wrist extension (classic provocative test)
The patient is an overhead/racquet sport player. Golfer's elbow affects the medial epicondyle with pain on resisted wrist flexion. Radial head fracture would show on X-ray. Tennis elbow fits perfectly here. (Confirmed by Campbell's Operative Orthopaedics and Bailey & Love's)
Q03. Pes Cavus is NOT associated with which of the following?
Answer: (c) Congenital Vertical Talus
Reason: Pes cavus (high-arched foot) is associated with:
- Spina bifida (neurological causes of cavus)
- Syringomyelia (neurological)
- Hammer toe deformity (forefoot pathology in cavus)
Congenital Vertical Talus produces a rocker-bottom flat foot (convex pes valgus) - the exact OPPOSITE of pes cavus. It causes a rigid flatfoot deformity, not high arch. Hence it is NOT associated with pes cavus.
Q04. Primary bone tumor in children with onion peel periosteal reaction
Answer: (b) Ewing's Sarcoma
Reason: The "onion peel" (or onion skin) periosteal reaction on X-ray is the classic and pathognomonic radiological sign of Ewing's Sarcoma. It occurs in children/adolescents and represents layers of reactive periosteum being lifted by the aggressive tumor. Histologically it shows small, round, blue cells. (Confirmed by both Tintinalli's and Harrison's Principles of Internal Medicine)
- Chondrosarcoma: lobulated calcifications ("popcorn"), adults
- Osteosarcoma: Codman's triangle / sunburst pattern
- Giant Cell Tumor: soap bubble, epiphysis, adults
Q05. Pavlik Harness is used to treat which condition?
Answer: (c) Developmental Dysplasia of Hip (DDH)
Reason: The Pavlik harness is the first-line treatment for DDH in infants under 6 months. It holds the hips in flexion and abduction (approximately 100° flexion, 50° abduction), promoting concentric reduction and acetabular development. It is NOT used for Perthe's disease (where abduction braces may be used), slipped capital femoral epiphyses, or osteogenesis imperfecta. (Confirmed by Campbell's Operative Orthopaedics and Miller's Review of Orthopaedics)
Q06. Posterior dislocation of knee - which vital structure is most at risk?
Answer: (a) Popliteal Artery
Reason: The popliteal artery is the most commonly and severely injured structure in knee dislocation. In posterior knee dislocation, the popliteal artery is directly compressed or torn between the dislocating tibia and the femoral condyles. The artery is tethered at the adductor hiatus proximally and the soleus arch distally, making it especially vulnerable to stretch and rupture. Limb-threatening ischemia can result. Vascular assessment (ABI or CT angiography) is mandatory. (Confirmed by Rosen's Emergency Medicine)
Q07. Phalen test is used to test which condition?
Answer: (d) Carpal Tunnel Syndrome
Reason: The Phalen test involves holding the wrists in sustained flexion (90°) for 60 seconds. Reproduction of tingling/numbness in the median nerve distribution (thumb, index, middle, and radial half of ring finger) is a positive test for Carpal Tunnel Syndrome (median nerve compression at the wrist). It has sensitivity ~75% and specificity ~47%. (Confirmed by Campbell's Operative Orthopaedics and Rheumatology textbook)
Q08. Which is NOT a criterion for joint hypermobility/hyper-mobility syndrome?
Answer: (b) Passive eversion of the ankle joint beyond 20 degrees
Reason: The Beighton Score criteria for joint hypermobility are:
- Passive dorsiflexion of 5th MCP beyond 90°
- Elbow hyperextension > 10° (NOT 10°) - passive extension of elbow beyond 10 degrees (1 pt each)
- Knee hyperextension > 10°
- Passive thumb apposition to volar forearm
- Forward flexion of trunk with knees extended, palms flat on floor
Passive eversion of the ankle beyond 20 degrees is NOT a Beighton criterion - ankle eversion is not part of the standard Beighton scoring system. (Confirmed by Miller's Review of Orthopaedics)
IMAGE 2 (Page 2 - Questions 09-16)
Q09. 60-year-old woman, bilateral knee pain, synovial thickening, joint space narrowing, sclerosis, cysts, osteophytes at articular margins
Answer: (c) Osteoarthritis
Reason: This is the classic X-ray description of Osteoarthritis:
- Joint space narrowing
- Subchondral sclerosis
- Subchondral cysts
- Osteophytes at articular margins
- Synovial fluid excess (effusion) is also common
Rheumatoid arthritis shows erosions, periarticular osteoporosis, and symmetric small joint involvement. Gout shows soft tissue tophi and erosions. Neuropathic joint (Charcot) shows severe joint destruction with fragmentation.
Q10. 52-year-old woman, hypothyroidism, left knee, intra-articular calcium deposition on X-ray
Answer: (c) Pseudogout
Reason: Pseudogout (Calcium Pyrophosphate Deposition - CPPD disease) is characterized by:
- Intra-articular calcium deposition (chondrocalcinosis) visible on X-ray
- Association with hypothyroidism, hyperparathyroidism, hemochromatosis
- Knee is the most commonly affected joint
- Crystals are positively birefringent rhomboid-shaped calcium pyrophosphate crystals
Gout shows needle-shaped negatively birefringent urate crystals and is associated with hyperuricemia. OA does not show calcium deposits. RA is seronegative/seropositive with erosions.
Q11. 45-year-old woman, fell on uneven surface, swollen painful knee, unable to straight leg raise
Answer: (b) Haemarthrosis
Reason: Inability to perform a straight leg raise in the context of a swollen, painful knee after trauma strongly suggests a haemarthrosis (blood in the joint). This is a non-specific but critical sign. The most common causes of traumatic haemarthrosis are ACL rupture (~70%), peripheral meniscal tear, patellar dislocation. The swollen tense knee from blood prevents quadriceps activation.
Note: Option (a) Anterior cruciate rupture could also be considered, but haemarthrosis is the more immediate finding explaining the presentation. The inability to straight leg raise + swollen knee = haemarthrosis is the answer being tested.
Q12. 25-year-old rugby player, heard a "pop," knee swelling, difficulty climbing stairs
Answer: (a) Anterior Cruciate Rupture
Reason: The classic ACL injury presentation:
- Mechanism: twisting/pivoting injury during sport (rugby line-out, landing awkwardly)
- Audible/felt "pop" at the time of injury
- Immediate haemarthrosis (rapid swelling within 1-2 hours)
- Difficulty climbing stairs / knee instability
- Positive Lachman and anterior drawer tests
This triad (sport, pop, immediate swelling) is pathognomonic for ACL tear.
Q13. Dashboard knee injury, haemarthrosis, no bony injury, difficulty walking DOWN stairs
Answer: (d) Posterior Cruciate Ligament (PCL)
Reason:
- Mechanism: Dashboard injury = direct blow to anterior tibia forcing it posteriorly - classic PCL injury mechanism
- Symptom: Difficulty walking DOWN stairs (posterior sag due to PCL laxity makes descending stairs painful/difficult)
- No bony injury on X-ray (ligamentous injury)
- PCL is the strongest ligament in the knee; posterior drawer test positive
MCL injury would be medial pain with valgus stress. LCL would be lateral pain. Patella fracture would show on X-ray.
Q14. Closed femoral shaft fracture, 1 day post-injury, low-grade pyrexia, tachycardia, RR 36, declining urine output, rash on upper chest
Answer: (c) Fat Embolism Syndrome
Reason: The classic triad of Fat Embolism Syndrome (FES):
- Respiratory distress (RR 36 breaths/min)
- Neurological changes (anxiety)
- Petechial rash - typically on upper chest, axillae, conjunctivae (pathognomonic)
Plus: Low-grade fever, tachycardia, after long bone fracture (femoral shaft) within 24-72 hours. Fat globules from bone marrow embolize to lungs and skin causing this picture. DVT/PE would not cause petechial rash. Compartment syndrome causes pain out of proportion to injury.
Gurd's criteria for FES includes: major criteria (respiratory insufficiency, CNS changes, petechial rash) + minor (fever, tachycardia, thrombocytopenia, fat macroglobulinemia).
Q15. 18-year-old, progressive swelling of distal thigh for 1 year, NO weight loss/appetite loss, X-ray shown
Answer: (e) Simple Bone Cyst (or Aneurysmal Bone Cyst)
Reason: Age 18, no systemic symptoms (no weight/appetite loss), slow progressive swelling over 1 year in distal thigh - this points to a benign lesion. Without seeing the X-ray clearly, but given:
- No constitutional symptoms (rules out osteogenic sarcoma which has weight loss)
- Young patient, distal femur location
If the X-ray shows a well-defined lytic lesion: Simple Bone Cyst or Aneurysmal Bone Cyst.
Compare to Q20 which has weight loss → Osteogenic Sarcoma.
(Note: The answer depends on the X-ray appearance shown; benign lesion without systemic symptoms = Simple bone cyst most likely)
Q16. 10-year-old boy, fall without stretch hand, pain in right wrist, X-ray shown
Answer: (e) Torus Fracture
Reason: A Torus (Buckle) fracture is the most common fracture in children in the distal radius/wrist:
- Mechanism: fall on outstretched hand (FOOSH) - though question says "without stretch" suggesting a direct compression/buckling mechanism
- Age: children (cortex is softer)
- X-ray: buckling/bulging of the cortex without complete break
- The cortex buckles (torus = Latin for bulge) on the compression side
Greenstick fracture shows incomplete fracture with bending. Salter-Harris involves the growth plate. Torus = compression buckle fracture on one cortex. This is the classic answer for a young child with distal radius injury.
IMAGE 3 (Page 3 - Questions 17-30)
Q17. 9-year-old girl, fell from 10 feet, unable to walk, swelling at distal thigh, X-ray shown
Answer: (d) Salter-Harris Type I Injury
Reason: In children, the physis (growth plate) is the weakest part of the bone. A fall from height in a 9-year-old girl with distal thigh swelling most likely represents a Salter-Harris fracture through the growth plate. Type I is a pure physeal separation (straight through the growth plate) without metaphyseal or epiphyseal fracture. X-ray may show only widening of the growth plate. Common in distal femur.
Q18. 10-year-old boy, shoulder pain for 9 months during cricket, unable to move shoulder, proximal arm swelling, X-ray shown
Answer: (b) Pathological Fracture
Reason: A 10-year-old with chronic shoulder pain (9 months) that suddenly increased during minimal activity (cricket) with proximal arm swelling suggests a pathological fracture through a pre-existing lesion (e.g., unicameral bone cyst, fibrous dysplasia). The X-ray of the proximal humerus in this context typically shows a lytic lesion with fracture. A simple bone cyst in the proximal humerus is the most common cause of pathological fracture in children ("fallen leaf" sign on X-ray - cortical fragment settling to the dependent part of the cyst).
Q19. 20-year-old male, RTA, open leg injury, 2 cm wound, exposed fracture bone, X-ray shown with butterfly fragment
Answer: (c) Fracture with large butterfly fragment
Reason: The X-ray is described/shown with a butterfly fragment. A butterfly fragment is a triangular wedge-shaped cortical fragment produced by bending forces. It is a third fragment that separates from the main fracture fragments. Combined with the open wound, this is a compound (open) fracture with a large butterfly fragment. This is distinct from a simple, segmental, or comminuted fracture pattern.
Q20. 18-year-old, distal thigh swelling for 1 year, progressively increasing, WITH loss of weight and appetite
Answer: (d) Osteogenic Sarcoma
Reason: The key difference from Q15 is the presence of constitutional symptoms (weight loss and appetite loss). In a young patient (peak 10-20 years) with:
- Distal femur/proximal tibia location (most common site)
- Progressive swelling
- Systemic symptoms (weight loss, anorexia)
- X-ray: Codman's triangle + sunburst/spiculated periosteal reaction
This is Osteosarcoma - the most common primary malignant bone tumor in adolescents.
Q21. 30-year-old, fall on outstretched hand, anterior dislocation of RIGHT shoulder - nerve injured commonly?
Answer: (b) Axillary Nerve
Reason: The axillary nerve is the most commonly injured nerve in anterior shoulder dislocation. It runs through the quadrilateral space immediately inferior to the glenohumeral joint. During anterior dislocation, the humeral head displaces anteriorly/inferiorly and stretches/compresses the axillary nerve.
- Test: sensation over "regimental badge" area (lateral deltoid)
- Motor: deltoid weakness
- Must always test before and after reduction
Q22. 30-year-old, fall on outstretched hand, R arm injury (X-ray shows radial head/neck or mid-shaft radius fracture)
Answer: (c) Radial Nerve
Reason: Based on the X-ray context (radial fracture), the radial nerve is at risk with fractures of the proximal/mid-shaft humerus (Holstein-Lewis fracture) or proximal radius injuries. The radial nerve winds around the spiral groove of the humerus. However, if this refers to a Monteggia fracture (ulna fracture + radial head dislocation), the posterior interosseous nerve (PIN) - a branch of radial nerve - is at risk. For mid-shaft humerus fractures: radial nerve.
Q23. 6-year-old child, fell from bed, displaced supracondylar fracture of humerus - nerve commonly injured?
Answer: (a) Anterior Interosseous Nerve (AIN)
Reason: In displaced supracondylar fracture of humerus in children:
- The anterior interosseous nerve (branch of median nerve) is the most commonly injured nerve
- It supplies FPL, FDP to index/middle, pronator quadratus
- Test: "OK sign" - patient cannot make a perfect circle (FPL + FDP index)
- The median nerve itself can also be injured, but AIN is the most specific answer
- The radial nerve can also be injured but less commonly than AIN in this injury pattern
Q24. 5-year-old, supracondylar fracture treated surgically, post-op Froment's sign positive - nerve injured?
Answer: (e) Ulnar Nerve
Reason: Froment's sign is specifically the test for ulnar nerve palsy:
- Patient tries to hold a piece of paper between thumb and index finger
- With ulnar nerve palsy, the adductor pollicis (ulnar innervated) is weak
- Patient compensates by flexing the IP joint of thumb (using FPL - median nerve) = positive Froment's sign
In supracondylar fracture surgically treated with K-wire fixation, the ulnar nerve can be iatrogenically injured, especially with medial K-wire insertion. Post-operative Froment's sign = ulnar nerve injury.
Q25. Newborn with bilateral talipes equinovarus (CTEV) - recommended treatment?
Answer: (d) Ponseti Casting
Reason: The Ponseti method is the gold standard treatment for congenital talipes equinovarus (clubfoot):
- Series of weekly manipulations and casts for 6-8 weeks
- Corrects the deformity in order: Cavus → Adductus → Varus → Equinus (CAVE)
- Usually followed by percutaneous Achilles tenotomy
- Then Foot Abduction Orthosis (Denis Browne splint)
- Success rate >90%
Botox in calf and physiotherapy are adjuncts, not the primary treatment. Posteromedial release is surgical and reserved for failures.
Q26. 55-year-old post-menopausal woman with BMD report asking for bisphosphonate therapy - at what T-score?
Answer: (e) -2.5
Reason: According to WHO criteria and standard guidelines:
- T-score > -1.0: Normal
- T-score -1.0 to -2.5: Osteopenia
- T-score ≤ -2.5: Osteoporosis - threshold for bisphosphonate therapy
Bisphosphonates (alendronate, risedronate, zoledronic acid) are started at T-score ≤ -2.5, or at -1.0 to -2.5 if additional risk factors (FRAX score, prior fracture) are present. The question asks specifically when to START bisphosphonate = T-score of -2.5.
Q27. 30-year-old male, RTA, isolated femoral shaft fracture, X-ray shown - ideal treatment?
Answer: (b) Interlocking Nail
Reason: Interlocking Intramedullary Nail is the gold standard treatment for femoral shaft fractures in adults:
- Controls rotation (via locking bolts proximally and distally)
- Allows early weight bearing
- Low infection rate
- Preserves bone biology (closed technique)
- Elastic nails are used in children (flexible IM nails for pediatric femur fractures)
- Plates and screws are used for fractures not suitable for nailing (proximal/distal femur)
- Plaster cast is inadequate for femoral shaft fractures in adults
Q28. 15-month-old child, knee deformity, X-ray shown - treatment option?
Answer: (e) Observation
Reason: At 15 months of age (just beginning to walk), physiological genu varum (bow-legged) is absolutely normal. Children normally have:
- Genu varum at birth to ~18-24 months
- Neutral alignment around 18 months - 2 years
- Genu valgum from 3-4 years
- Adult alignment by 6-7 years
At 15 months, genu varum is normal developmental alignment and requires only observation/reassurance. No treatment is necessary. Intervention (bracing, surgery) is only considered for pathological causes (Blount's disease, rickets) or severe/progressive deformity.
Q29. 2-year-old child with cerebral palsy, soft equinus deformity of both ankles - recommended treatment?
Answer: (a) Botox Injections in Calf
Reason: In a young child (2 years) with cerebral palsy and soft (dynamic) equinus deformity:
- The deformity is not yet fixed/structural
- Botulinum toxin injection into the gastrocnemius/soleus complex reduces spasticity, allows physiotherapy, and delays fixed contracture
- It is the most appropriate first-line treatment in young children with dynamic (not fixed) equinus
- Ponseti casting is for clubfoot, not spastic equinus
- Intrathecal baclofen is for severe generalized spasticity
- Surgery (TAL/Achilles lengthening) is for fixed deformity, not appropriate at age 2 with soft deformity
Q30. 6-year-old child, supracondylar fracture of humerus in cast for 4 weeks, on removal has restricted elbow range of motion - what next?
Answer: (e) Reassurance
Reason: After supracondylar fracture in a child treated conservatively in cast:
- Stiffness and restricted ROM are expected and normal after 4 weeks of immobilization
- In children, elbow ROM recovers spontaneously and completely in most cases within 3-6 months
- Reassurance and gentle active exercises are the appropriate management
- Aggressive physiotherapy can lead to heterotopic ossification (myositis ossificans) in children - it is actually contraindicated
- Manipulation under anesthesia is dangerous and not indicated at this stage
- Reapplication of cast would worsen stiffness
This is a classic teaching point: aggressive physiotherapy MUST be avoided after elbow fractures/dislocations as it causes myositis ossificans.

I have the Gustilo-Anderson classification confirmed from the textbook and sufficient knowledge to answer all questions. Here are all answers with full reasoning:
True or False - Complete Answers with Reasons
Q01. Osteomalacia is characterized by clinical features such as:
| Statement | Answer | Reason | |
|---|---|---|---|
| a | Body pains | TRUE | Bone pain (diffuse, dull aching) is a cardinal feature of osteomalacia due to unmineralized osteoid accumulation under the periosteum |
| b | Muscle Weakness | TRUE | Proximal myopathy (muscle weakness) is a classic feature of osteomalacia, caused by hypophosphatemia and vitamin D deficiency affecting muscle cell function |
| c | Muscle Swelling | FALSE | Muscle swelling is NOT a feature of osteomalacia. Osteomalacia causes muscle weakness and wasting, not swelling |
| d | Fragility fractures | TRUE | Osteomalacia causes softening of bone due to defective mineralization, leading to Looser zones (pseudofractures) and fragility/insufficiency fractures |
Key: T T F T ✓ (matches the written answer TTFT)
Q02. Regarding peripheral neuropathies:
| Statement | Answer | Reason | |
|---|---|---|---|
| a | Nerve entrapment of the lateral cutaneous nerve of thigh is an example of mononeuritis multiplex | FALSE | Entrapment of the lateral cutaneous nerve of thigh causes meralgia paresthetica - a simple mononeuropathy (single nerve), NOT mononeuritis multiplex (which involves multiple separate nerves simultaneously, e.g., in vasculitis/diabetes) |
| b | Partial simultaneous involvement of individual noncontiguous nerve trunks is a hallmark of diabetic neuropathy | FALSE | That description is mononeuritis multiplex, which is hallmark of vasculitis/leprosy. Diabetic neuropathy is classically a symmetrical, length-dependent polyneuropathy ("stocking and glove") |
| c | Vitamin B12 deficiency leads to polyneuropathy | TRUE | B12 deficiency causes subacute combined degeneration of the spinal cord AND peripheral polyneuropathy (predominantly sensory, affecting posterior columns) |
| d | Femoral nerve is the commonest site for nerve biopsy | FALSE | The sural nerve is the most commonly biopsied nerve - it is purely sensory, easily accessible at the ankle, and its sacrifice causes minimal morbidity |
Key: F F T F ✓ (matches FFTF)
Q03. Following statements are correct regarding the diagnosis of Carpal Tunnel Syndrome:
| Statement | Answer | Reason | |
|---|---|---|---|
| a | Patients often complain of shaking their wrists to relieve the discomfort | TRUE | This is called the "flick sign" - a classic and highly specific symptom of CTS. Patients shake/flick their wrists (like shaking a thermometer) to relieve the tingling/pain |
| b | Tinel sign can be elicited by flexing the wrist to 90 degrees | FALSE | Tinel's sign is elicited by tapping (percussion) over the carpal tunnel at the wrist. Flexing the wrist to 60-90° is the Phalen's test, not Tinel's |
| c | EMG and Nerve conduction studies are often used to confirm diagnosis | TRUE | Nerve conduction studies (NCS) and EMG are the gold standard investigations to confirm CTS - they show delayed sensory/motor conduction across the carpal tunnel |
| d | Wasting of hypothenar eminence happens late after the onset of the disease | FALSE | In CTS, the median nerve supplies the thenar eminence (LOAF muscles). It is thenar wasting, not hypothenar, that occurs late. Hypothenar wasting suggests ulnar nerve pathology |
Key: T F T F ✓ (matches TFTF)
Q04. Following steps should be taken immediately in case of suspected Compartment Syndrome:
| Statement | Answer | Reason | |
|---|---|---|---|
| a | Release of all circumferential dressings | TRUE | Immediate removal of all circumferential casts, bandages, and dressings is the FIRST step - they externally compress the compartment and raise pressure |
| b | Elevation of limb to above heart level | FALSE | Elevation is contraindicated in compartment syndrome - it reduces arterial perfusion pressure, worsening ischemia. The limb should be kept at heart level |
| c | Intravenous high dose opioid analgesia | FALSE | Opioid analgesia may mask the pain (a key diagnostic sign) and delays definitive treatment. It is NOT part of emergency management |
| d | Surgical decompression (Fasciotomy) | TRUE | Fasciotomy is the definitive treatment - urgent surgical release of the fascial compartments when compartment pressure exceeds 30 mmHg (or within 30 mmHg of diastolic BP) |
Key: T F F T ✓ (matches TFFT)
Q05. Correct strategies in the treatment of Hallux Valgus:
| Statement | Answer | Reason | |
|---|---|---|---|
| a | Toe spacers and stretching exercises can be used for severe cases | FALSE | Toe spacers/splints and exercises are conservative measures suitable for mild-moderate cases only. Severe hallux valgus requires surgical correction |
| b | Surgery is often the first line of treatment | FALSE | Surgery is reserved for cases that fail conservative treatment. Conservative management (wide toe-box shoes, toe spacers, insoles, physiotherapy) is always first-line |
| c | Painful hallux valgus can result in hallux rigidus | FALSE | Hallux rigidus (OA of the 1st MTP joint causing stiffness) is a separate condition from hallux valgus (lateral deviation of the big toe). While both affect the 1st MTP, painful hallux valgus does not directly cause hallux rigidus |
| d | Shoe wear modification is helpful in the initial stages of treatment | TRUE | Wide toe-box shoes, avoiding pointed/narrow footwear, and low heels are the cornerstone of initial conservative management for hallux valgus |
Key: F F F T (Note: The written answers on the paper appear to show F F F T for this question)
Q06. Regarding dislocations of the shoulder joint:
| Statement | Answer | Reason | |
|---|---|---|---|
| a | Posterior dislocation is the commonest site of femoral head displacement | FALSE | This statement confuses shoulder and hip. For shoulder, anterior dislocation is the commonest (95-97%). For hip, posterior dislocation is the commonest. The statement incorrectly applies "femoral head" to shoulder context, and is also factually confused |
| b | Anterio-inferior dislocation is reduced by Hippocratic method | TRUE | The Hippocratic technique involves the operator placing their foot in the axilla for counter-traction while applying longitudinal traction on the arm - used for anterior-inferior shoulder dislocation |
| c | Structure that is commonly at risk is the circumflex humeral artery | FALSE | The axillary nerve is the most commonly injured structure in anterior shoulder dislocation (not the circumflex humeral artery). The anterior circumflex humeral artery may be involved but is less clinically significant than axillary nerve injury |
| d | (implied - high risk of humeral head fractures) | TRUE | Shoulder dislocation, especially in older patients, can result in greater tuberosity fractures and Hill-Sachs lesion (compression fracture of humeral head) |
Key: F T F T ✓ (matches FTFT)
Q07. Emergency steps in open fractures in the ER:
| Statement | Answer | Reason | |
|---|---|---|---|
| a | Immediate debridement | TRUE | Wound debridement (irrigation and removal of necrotic/contaminated tissue) is essential - though in ER this begins with wound irrigation; formal surgical debridement is done in OR urgently |
| b | Tetanus prophylaxis | TRUE | All open fractures require tetanus prophylaxis (toxoid ± immunoglobulin depending on vaccination status) - mandatory in contaminated wounds |
| c | Broad spectrum IV antibiotics | FALSE | For Grade I-II open fractures, 1st generation cephalosporin (e.g., cefazolin) covering gram-positive organisms is used, NOT broad-spectrum. Broad spectrum (adding gram-negative cover with aminoglycoside) is for Grade III. The statement is partially true for high-grade but not universally "broad spectrum" as first choice |
| d | Sterile dressing | TRUE | After initial wound assessment, applying a sterile dressing to cover the wound and prevent further contamination is a key immediate step |
Key: T T F T ✓ (matches TTFT)
Q08. Correct statements regarding mechanical lower back pain:
| Statement | Answer | Reason | |
|---|---|---|---|
| a | It is twice as common in females as compared to males | FALSE | Mechanical LBP affects males and females equally (M=F). Some sources suggest slight male preponderance in occupational/heavy lifting contexts. It is NOT twice as common in females |
| b | It is most commonly caused by disorders within the intervertebral disc | TRUE | Intervertebral disc degeneration/prolapse is the single most common structural cause of mechanical LBP. Disc disorders account for ~40% of LBP cases |
| c | Posture correction and muscle conditioning is mainstay of treatment and prevention | TRUE | Core muscle strengthening, posture correction, back school exercises, and ergonomic modification are the mainstays of both treatment and long-term prevention of mechanical LBP |
| d | Anti-depressants have no role in the management of this condition | FALSE | Tricyclic antidepressants (amitriptyline) and SNRIs (duloxetine) have a well-established role in chronic LBP management - they modulate central pain sensitization pathways and improve sleep. They are recommended in chronic/persistent LBP |
Key: F T T F ✓ (matches FTTF)
Q09. Gustilo and Anderson classification of open fractures:
| Statement | Answer | Reason | |
|---|---|---|---|
| a | A simple fracture with wound <1cm, clean with minimal soft tissue injury is Grade I | TRUE | Grade I: wound <1 cm, clean, low energy, minimal soft tissue injury ✓ (confirmed by Tintinalli's EM) |
| b | A comminuted fracture with wound >1cm with moderate soft tissue injury is Grade II | FALSE | Grade II: wound 1-10 cm with moderate soft tissue injury. The statement says ">1cm" which is incomplete - Grade II specifically means 1 to 10 cm. A wound >10 cm = Grade III |
| c | A crush injury with laceration >10cm with soft tissue coverage of bone possible is Grade IIIA | TRUE | Grade IIIA: high-energy fracture, wound >10 cm, gross contamination BUT adequate soft tissue coverage of bone is still possible ✓ |
| d | A highly contaminated crush injury with laceration >10cm with soft tissue coverage of bone possible is Grade IIIB | FALSE | Grade IIIB: wound >10 cm with inadequate/impossible soft tissue coverage (exposed bone requiring flap coverage). If soft tissue coverage is STILL POSSIBLE, it's IIIA, not IIIB |

Q10. Following are X-linked congenital conditions:
| Statement | Answer | Reason | |
|---|---|---|---|
| a | Duchenne muscular dystrophy | TRUE | DMD is X-linked recessive - caused by mutation in the dystrophin gene on chromosome Xp21. Affects males predominantly |
| b | Distal muscular dystrophy | FALSE | Distal muscular dystrophies (Welander, Miyoshi, Nonaka types) are autosomal dominant or autosomal recessive, NOT X-linked |
| c | Becker muscular dystrophy | TRUE | BMD is also X-linked recessive - same gene as DMD (dystrophin), but less severe mutation. Males affected |
| d | Emery-Dreifuss muscular dystrophy | TRUE | Emery-Dreifuss MD exists in both X-linked (emerin gene, Xq28) and autosomal forms. The classic form is X-linked recessive |

Q11. Features of Duchenne Muscular Dystrophy:
| Statement | Answer | Reason | |
|---|---|---|---|
| a | Sex-linked disease | TRUE | DMD is X-linked recessive - affects males (1 in 3500 male births); females are carriers |
| b | Pseudo-hypertrophy of calf muscle | TRUE | Calf pseudohypertrophy (due to replacement of muscle by fat and fibrous tissue) is the CLASSIC and pathognomonic feature of DMD |
| c | Pseudo-hypertrophy of deltoid | FALSE | Pseudohypertrophy in DMD is characteristically of the calves (gastrocnemius). Deltoid pseudohypertrophy can occur rarely but is NOT a classic defining feature. The characteristic pseudohypertrophy = calf |
| d | Forward tilt of pelvis | FALSE | DMD causes lordosis due to hip extensor weakness, with a backward tilt (anterior pelvic tilt = lordotic posture), and Trendelenburg gait/waddling gait. "Forward tilt" as stated is incorrect - it is actually exaggerated lumbar lordosis |

Q12. Management of acute septic arthritis includes:
| Statement | Answer | Reason | |
|---|---|---|---|
| a | Empirical antibiotic | TRUE | Broad-spectrum empirical IV antibiotics (covering S. aureus typically - flucloxacillin or vancomycin) must be started immediately after joint aspiration for culture, without waiting for results |
| b | Oral antibiotic | FALSE | Acute septic arthritis requires IV antibiotics initially (not oral) due to poor joint penetration with oral agents in the acute setting. Oral step-down is considered only after clinical improvement |
| c | Traction | FALSE | Traction is NOT a standard treatment for septic arthritis. It may be used as an adjunct to decompress a joint (e.g., hip) in some settings but is not a management step |
| d | Incision and drainage | TRUE | Surgical drainage (arthrotomy or arthroscopic washout) is essential in septic arthritis - the purulent joint fluid must be drained. Joint aspiration alone may be insufficient for established septic arthritis |

Q13. Investigation of acute osteomyelitis includes:
| Statement | Answer | Reason | |
|---|---|---|---|
| a | X-rays AP and Lateral | FALSE | In acute osteomyelitis, X-rays are initially normal for the first 10-21 days (bone destruction not visible until 30-50% of bone density lost). X-rays are NOT useful in the acute stage |
| b | MRI | TRUE | MRI is the most sensitive and specific investigation for acute osteomyelitis - it shows bone marrow edema, soft tissue involvement, and subperiosteal collection early. It is the investigation of choice |
| c | Sinogram | FALSE | A sinogram (contrast injection through a sinus tract) is used in chronic osteomyelitis to trace the tract and identify sequestrum, not acute osteomyelitis |
| d | Culture and sensitivity | TRUE | Blood cultures AND aspiration/biopsy cultures are essential to identify the causative organism and guide targeted antibiotic therapy |

Q14. Following are classifications of closed fractures:
| Statement | Answer | Reason | |
|---|---|---|---|
| a | Garden's (classification) | TRUE | Garden's classification is used for intracapsular femoral neck fractures (subcapital): Grades I-IV based on displacement and trabecular alignment |
| b | Gustello (Gustilo) | FALSE | Gustilo-Anderson is the classification for OPEN fractures, NOT closed fractures |
| c | Schatzker | TRUE | Schatzker classification is for tibial plateau fractures (closed fractures) - Types I to VI based on fracture pattern |
| d | Salter-Harris | FALSE | Salter-Harris is a classification for physeal (growth plate) fractures in children - these can be open or closed, and it's specifically for epiphyseal injuries, not a "closed fracture" classification per se. However, it IS technically a fracture classification and Salter-Harris fractures are usually closed |

Q15. Following conditions have male predominance:
| Statement | Answer | Reason | |
|---|---|---|---|
| a | Osteoporosis | FALSE | Osteoporosis predominantly affects post-menopausal women (female:male ratio ~3:1). Estrogen loss accelerates bone resorption. Males account for only ~20% of osteoporosis cases |
| b | Ankylosing Spondylitis | FALSE | While AS was historically considered to have strong male predominance (M:F = 3:1), recent studies show it is closer to equal (1:1) or only mildly male predominant. However, for exam purposes it is traditionally considered male predominant - so this is either TRUE or the answer on paper marks FALSE suggesting the examiners consider it NOT strongly male predominant. Based on the written answers showing F - the examiners appear to be marking this FALSE, suggesting equal sex ratio |
| c | Hemophilic arthritis | TRUE | Hemophilia (A and B) is X-linked recessive, affecting males almost exclusively. Hemophilic arthropathy from recurrent hemarthroses is therefore a male-predominant condition |
| d | Rheumatoid arthritis | FALSE (or TRUE per some sources) | RA is more common in females (F:M = 3:1). It is NOT male predominant. However, the written answer appears to show it as TRUE/FALSE ambiguously - RA is female predominant, so this should be FALSE |

Key High-Yield Points to Remember:
- Osteomalacia: Body pain + muscle weakness + fragility fractures = TRUE. Muscle swelling = FALSE
- CTS: Flick sign = TRUE; Tinel = tapping, NOT flexion = FALSE; Thenar (not hypothenar) wasting = FALSE
- Compartment Syndrome: Remove dressings + fasciotomy = TRUE; Elevation + opioids = FALSE
- Gustilo Grade IIIA vs IIIB: IIIA = soft tissue coverage POSSIBLE; IIIB = coverage NOT possible (needs flap)
- DMD: Calf pseudohypertrophy (not deltoid); X-linked; muscle weakness NOT swelling
- Septic arthritis: IV (not oral) antibiotics + surgical drainage
- Acute osteomyelitis: X-ray normal early; MRI = gold standard; sinogram = for CHRONIC OM
