MGR BPT Clinical Orthopaedics - Complete Explanations

SECTION A: 15-MARK LONG ESSAY QUESTIONS

1. Fractures - Pathology, Types, Clinical Features, Complications & PT Management (Bone Healing)

Definition: A fracture is a break in the continuity of bone, caused by direct or indirect trauma, pathological conditions, or stress.
Types of Fractures:
  • By skin integrity: Open (compound) vs Closed (simple)
  • By pattern: Transverse, oblique, spiral, comminuted, greenstick (children), impacted, avulsion, compression
  • By cause: Traumatic, pathological (through diseased bone), stress (fatigue)
Pathology - Bone Healing (Stages):
  1. Haematoma formation (0-72 hrs): Torn blood vessels form a clot; inflammation begins with release of growth factors
  2. Inflammatory phase (Days 1-7): Macrophages, fibroblasts invade; granulation tissue forms
  3. Soft callus (Weeks 2-3): Periosteal cells form fibrocartilage bridging the gap
  4. Hard callus (Weeks 3-12): Endochondral ossification converts cartilage to woven bone
  5. Remodelling (Months to years): Woven bone replaced by lamellar bone along stress lines (Wolff's Law)
Clinical Features:
  • Pain, tenderness at fracture site
  • Swelling, bruising/ecchymosis
  • Deformity, shortening, abnormal posture
  • Loss of function
  • Abnormal mobility, crepitus
  • Neurovascular deficit (if nerves/vessels involved)
Investigations: X-ray (AP + lateral views), CT scan (complex fractures), MRI (soft tissue, stress fractures), bone scan
Medical Management: RICE, immobilization (POP cast, splint), traction, ORIF (open reduction internal fixation), external fixation
Complications:
  • Immediate: Haemorrhage, neurovascular injury, visceral injury

  1. Serial casting (weekly for 5-8 weeks) - gradual correction of deformity in sequence: C → A → V → E
  2. Percutaneous Achilles tenotomy (to correct residual equinus - in 90% of cases)
  3. Maintenance with Dennis Browne abduction bar/foot abduction brace for 3 months full-time, then nights/naps until age 4-5 years
Surgical Management:
  • Posteromedial soft tissue release for failed conservative treatment
  • Tibialis anterior tendon transfer for residual dynamic supination
PT Management:
  • Infant: Stretching exercises (dorsiflexion, abduction, eversion), gentle manipulation before each cast
  • After casting: Passive stretching, active stimulation of peroneal muscles
  • Post-operative: Wound care, splinting, gradual ROM
  • Older children: Gait training, strengthening exercises
  • Parent education: Brace compliance, home stretching

17. CDH / DDH (Congenital/Developmental Dysplasia of Hip)

Definition: A spectrum of conditions ranging from acetabular dysplasia to subluxation to complete dislocation of the femoral head.
Incidence: 1-2 per 1000; female > male (6:1), left > right, breech presentation risk
Aetiology: Ligamentous laxity, breech position, female hormones (relaxin), family history, oligohydramnios, first-born
Clinical Tests:
  • Ortolani's test (Reduction test): Dislocated hip - gentle abduction and forward pressure on greater trochanter reduces the hip with a "clunk"
  • Barlow's test (Provocation test): In neutral - adduction and downward pressure dislocates a reducible hip
  • Galeazzi sign (Allis sign): In supine with hips and knees flexed - asymmetric knee heights (shorter on affected side)
  • Trendelenburg's sign: Positive (pelvis drops to opposite side when standing on affected leg) due to weak abductors
Grading (Graf Ultrasound Classification): Based on acetabular morphology and femoral head position - Type I (normal) to Type IV (dislocation)
Management by Age:
  • 0-6 months: Pavlik harness (maintains hip in flexion and abduction - Ramsey position: 90° flexion, 50-70° abduction)
  • 6-18 months: Closed reduction under GA + hip spica cast
  • 18 months to 3 years: Open reduction + Salter/Pemberton osteotomy + hip spica
  • > 3 years: More complex reconstructive surgery, poor outcome if untreated
PT Management:
  • Education of parents on maintaining position in Pavlik harness
  • ROM exercises during spica cast period (foot/ankle/knee)
  • Post-casting: Hip ROM, strengthening
  • Gait training after surgical correction
  • Monitoring for complications (AVN)

18. Poliomyelitis

Definition: A viral infection (Poliovirus - Enterovirus) causing destruction of anterior horn cells (lower motor neurons) in the spinal cord, resulting in flaccid paralysis.
Pathology:
  1. Oral-fecal transmission
  2. Virus multiplies in gut lymphoid tissue
  3. Viremia
  4. Anterior horn cell invasion and destruction
  5. Wallerian degeneration of lower motor neurons
  6. Flaccid paralysis of muscles supplied
Stages:
  1. Pre-paralytic stage: Fever, headache, vomiting, neck stiffness
  2. Paralytic stage: Asymmetric flaccid paralysis, loss of reflexes, hot and tender muscles
  3. Convalescent stage (6-24 months): Recovery of unaffected neurons; muscle recovery
  4. Residual paralysis stage: Permanent deficits; deformities develop
Characteristics of Paralysis:
  • Lower motor neuron type (flaccid, hypotonia, areflexia, muscle wasting)
  • Asymmetric, spotty distribution
  • Sensation preserved

  • Calcaneovalgus foot (weak plantar flexors)
  • Flail limb
  • Limb length discrepancy
  • Hip and knee contractures
  • Scoliosis (if paraspinal muscles affected)

Muscle Transfers (Tendon Transfers): Used to restore function by redirecting functional muscles to substitute for paralyzed ones:
  • Tibialis posterior to dorsum (for foot drop)
  • Tibialis anterior transfer
  • Prerequisites: Donor muscle must be at least 4/5 strength; joint must be mobile; antagonist must be present
Orthotics:
  • AFO (ankle-foot orthosis) for foot drop

  • Caliper (long leg brace)
PT Management:
  • Acute phase: Rest, positioning (splinting to prevent deformity), passive ROM

  • Residual phase: Strengthening remaining muscles, orthotic prescription, gait training
  • Tendon transfer post-op rehabilitation
  • Prevention of contractures
  • Breathing exercises if respiratory muscles affected
  • Post-polio syndrome: Energy conservation, pacing, avoiding overuse

19. Gait Analysis

SECTION C: 2-MARK SHORT ANSWER QUESTIONS

DEFINITIONS & TERMINOLOGY

Fracture; Types: A fracture is a break in the continuity of bone. Types: Transverse, oblique, spiral, comminuted, greenstick (children), impacted, stress, pathological, open, closed.
Dislocation vs Subluxation:
  • Dislocation: Complete loss of contact between two articular surfaces
  • Subluxation: Partial/incomplete loss of contact between articular surfaces (joint surfaces still in partial contact)
Coxa Vara / Coxa Valga:
  • Coxa Vara: Neck-shaft angle of femur < 120° (normal 125-135°); limb appears short, abductors lax
  • Coxa Valga: Neck-shaft angle > 135°; associated with hip dislocation
Varus vs Valgus:
  • Varus: Distal part of limb directed toward midline (inward angulation) - "bow-legged"
  • Valgus: Distal part directed away from midline (outward angulation) - "knock-kneed"
Osteotomy: Surgical cutting of bone to correct deformity, realign joint surfaces, or redistribute weight-bearing.
Arthrodesis: Surgical fusion of a joint to eliminate movement and relieve pain.
Arthroplasty: Surgical reshaping or replacement of a joint (total or partial joint replacement).
Bone Graft: Transplantation of bone tissue to repair skeletal defects; types: autograft (self), allograft (cadaver), synthetic.
Tenodesis: Surgical fixation of a tendon to bone; also refers to passive tenodesis effect (wrist extension causes passive finger flexion as in C6 SCI patients).
Wolff's Law: Bone remodels in response to the mechanical stresses placed upon it - bone is laid down where it is needed and reabsorbed where it is not.
Hilton's Law: The nerve supplying a joint also supplies the muscles that move the joint and the skin over those muscles.
Callus (Provisional & Permanent):
  • Provisional callus (soft callus): Fibrocartilaginous tissue bridging fracture gap at 2-3 weeks
  • Permanent callus (hard callus): Mineralised bone formed by ossification of soft callus; woven bone later remodelled to lamellar bone
Non-Union and Malunion:
  • Non-union: Failure of fracture to unite within the expected time (usually >6 months); can be hypertrophic (vascular), atrophic (avascular), or infected
  • Malunion: Fracture heals in an unacceptable position (shortening, angulation, or rotation)
Delayed Union: Fracture that takes longer than expected to heal but is still progressing toward union (distinguished from non-union where healing has stopped).
Avascular Necrosis (AVN): Death of bone tissue due to interruption of blood supply; leads to collapse of the articular surface. Common sites: Femoral head (after fracture neck of femur), scaphoid, talus.

CLINICAL SIGNS & SPECIAL TESTS

Trendelenburg Sign & Test:
  • Sign: When standing on one leg, the pelvis drops on the contralateral (non-weight-bearing) side - indicates weakness of ipsilateral hip abductors (gluteus medius and minimus)
  • Positive Trendelenburg: Patient compensates by lurching trunk to affected side = Trendelenburg gait
Thomas Test:
  • Tests for fixed flexion deformity (FFD) of the hip
  • Method: Patient supine, examiner flexes the contralateral hip fully to flatten lumbar lordosis; the angle the affected thigh makes with the bed is the degree of FFD
  • Positive: Affected hip lifts off bed = FFD present
Lachman's Test:
  • Tests ACL integrity
  • Method: Knee at 20-30° flexion; stabilize femur, pull tibia anteriorly; assess for soft end-point
  • Most sensitive test for ACL rupture
McMurray's Test:

  • Phalen's test: Maximal wrist flexion for 60 seconds reproduces tingling in median nerve distribution - for CTS
  • Tinel's sign: Percussion over carpal tunnel (or any nerve) elicits distal tingling in nerve distribution - tests nerve regeneration/hypersensitivity
Lasegue's Sign (SLR Test):
  • Patient supine; examiner passively raises extended leg
  • Positive: Reproduction of radicular pain (sciatica) at < 60° indicates L4/L5/S1 nerve root compression (PIVD)
  • Bowstring sign: Relieving leg at positive SLR angle by bending knee reduces pain; pressing popliteal fossa reproduces it
Schober's Test:
  • Measures lumbar flexion
  • Method: Mark 5 cm below and 10 cm above the L5-S1 junction (total 15 cm); patient bends forward; normal increase is ≥ 5 cm (from 15 to ≥ 20 cm)
  • Reduced in AS, mechanical LBP
Finkelstein's Test:
  • Tests De Quervain's tenosynovitis
  • Method: Patient places thumb in palm, wraps fingers over it; examiner deviates wrist in ulnar direction
  • Positive: Pain over radial styloid/first dorsal compartment
Apley's Grind & Distraction Test:
  • Grind: Patient prone, knee at 90°; compression applied + rotation - pain = meniscal tear
  • Distraction: Distract knee + rotation - pain = ligamentous injury
  • Together they differentiate meniscal from ligamentous pathology
Speed's / Yergason's Test:
  • Speed's test: Resisted shoulder flexion with elbow extended and forearm supinated - pain in bicipital groove = bicipital tendinitis
  • Yergason's test: Resisted supination with elbow at 90° flexion - pain in bicipital groove = bicipital tendinitis
Hawkins-Kennedy Test:
  • Tests for subacromial impingement
  • Method: Shoulder and elbow at 90° flexion; internally rotate shoulder
  • Positive: Pain = impingement of supraspinatus
Cobb's Angle: (Covered above - Scoliosis section) The angle between lines drawn along end plates of the most tilted upper and lower vertebrae in a scoliotic curve; measured on AP spine X-ray.
Gaenslen's Test:
  • Tests sacroiliac joint
  • Method: Patient supine at edge of table; one hip hyperextended off the table, other hip maximally flexed; positive if this stresses the SI joint and reproduces buttock pain
  • Positive in sacroiliitis (AS, mechanical SI joint dysfunction)

DEFORMITIES & SHORT CONCEPTS

Wrist Drop: Inability to extend the wrist due to radial nerve palsy; hand hangs in flexion.
Foot Drop: Inability to dorsiflex the foot due to common peroneal nerve injury or weakness of tibialis anterior; causes high-stepping gait.
Ape Hand: Thenar wasting with thumb in the plane of the palm due to median nerve injury (loss of thenar opposition muscles - APB, OP, FPB).
Claw Hand: Hyperextension at MCP and flexion at IP joints of ring and little fingers due to ulnar nerve palsy (loss of interossei and hypothenar muscles); intrinsic minus position.
Swan Neck Deformity: Hyperextension at PIP joint and flexion at DIP joint; caused by intrinsic muscle tightness or volar plate injury at PIP; seen in RA.
Boutonniere Deformity: Flexion at PIP and hyperextension at DIP joint; caused by disruption of central slip of extensor tendon allowing lateral bands to slip volarly; seen in RA, trauma.
Mallet Finger: Flexion deformity at DIP joint due to rupture of extensor tendon at its insertion on distal phalanx; caused by forced flexion of extended finger; treated with extension splint for 6-8 weeks.
Trigger Finger: Stenosing tenosynovitis of the flexor tendon sheath causing the tendon to catch or lock when passing through the A1 pulley; finger "clicks" and locks in flexion; treated with steroid injection or surgical release.
Heberden's vs Bouchard's Node:
  • Heberden's nodes: Osteophytes at DIP joints - seen in OA
  • Bouchard's nodes: Osteophytes at PIP joints - seen in OA (can also be seen in RA)
RICE / PRICES Principle:
  • RICE: Rest, Ice, Compression, Elevation (acute soft tissue injury management)
  • PRICES: Protection, Rest, Ice, Compression, Elevation, Support
Spinal Shock: Temporary loss of all spinal cord functions (motor, sensory, reflex, autonomic) below the level of injury immediately after acute SCI; lasts hours to days/weeks; resolution marked by return of bulbocavernosus reflex.
Brown-Sequard Syndrome: Hemisection of spinal cord causing: ipsilateral loss of motor function and proprioception/vibration (posterior column and corticospinal tract); contralateral loss of pain and temperature (spinothalamic tract crosses 2 levels above).
Cauda Equina Syndrome: Compression of the cauda equina nerve roots causing: bilateral leg pain/weakness, saddle area anaesthesia, urinary retention (overflow incontinence), bowel dysfunction; surgical emergency.
Meralgia Paraesthetica: Compression/entrapment of lateral femoral cutaneous nerve (L2-L3) at the inguinal ligament; causes burning, tingling, numbness on anterolateral thigh; no motor involvement; causes: obesity, tight belts, pregnancy.
Tarsal Tunnel Syndrome: Compression of posterior tibial nerve within tarsal tunnel (behind medial malleolus); causes pain and tingling on sole of foot; Tinel's sign positive at tarsal tunnel.
Crutch Palsy: Compression of radial nerve in axilla (posterior cord of brachial plexus) from crutch pressure; causes wrist drop and weakness of finger extensors; triceps typically spared as branch is given off above the radial groove.
Erb's Palsy: (Covered above - Upper brachial plexus C5, C6 injury; "waiter's tip" posture)
Klumpke's Palsy: Lower brachial plexus injury (C8, T1); intrinsic hand muscle wasting (claw hand), sensory loss medial forearm/hand; associated Horner's syndrome (if T1 ramus communicans involved - ptosis, miosis, anhidrosis).

APPLIANCES & EQUIPMENT

Types of Crutches:
  • Axillary crutches: Rest in axilla; risk of crutch palsy if used improperly (weight through axilla not hands)
  • Elbow crutches (Lofstrand/forearm): Cuff around forearm, handgrip; most common
  • Gutter crutches: Forearm rests in gutter; for those who cannot grip (RA)
  • Gait patterns: Non-weight bearing (swing through), partial weight bearing (3-point), full weight bearing (4-point, 2-point)
Thomas Splint:
  • Half-ring splint that fits around the thigh at ischial tuberosity and extends beyond the foot
  • Used for femoral shaft fractures (with skin/skeletal traction)
  • Used with Pearson knee flexion piece for balanced suspension traction
  • Also used as temporary splinting in emergency/transport
Hip Spica:
  • Plaster of Paris cast encasing the pelvis and one or both legs
  • Used for: CDH/DDH (post-reduction), hip fractures in children, pelvic osteotomies, femoral fractures in young children
Skeletal vs Skin Traction:
  • Skin traction: Applied via adhesive or foam strapping on skin; max weight 4-5 kg; short-term; risk of skin breakdown; for pediatric femur fractures, hip pain management
  • Skeletal traction: Pin (Steinmann pin or K-wire) through bone (distal femur, proximal tibia, calcaneum); heavier weights; long-term; more effective and accurate
KAFO / AFO / TLSO:
  • AFO (Ankle-Foot Orthosis): Controls ankle and foot; used for foot drop, equinus; types: solid, hinged, posterior leaf spring
  • KAFO (Knee-Ankle-Foot Orthosis): Controls knee, ankle, and foot; used for polio, SCI, severe OA
  • TLSO (Thoracolumbar-Sacral Orthosis): Encompasses thoracic, lumbar, sacral spine; used for scoliosis (Boston brace), compression fractures, post-spinal fusion
Milwaukee Brace:
  • A cervico-thoracolumbar orthosis (CTLSO)
  • Metal uprights with pelvic girdle and neck ring with chin/occipital pads
  • Used for: High thoracic scoliosis (apex T7 or above), some Scheuermann's kyphosis cases
  • Must be worn 18-23 hours/day in skeletally immature patients with Cobb's angle 25-45°
This covers all questions in the MGR BPT Clinical Orthopaedics Quick Reference Guide - all 19 long essay (15-mark) topics, all ~60 short note (5-mark) topics, and all ~60 short answer (2-mark) topics.
Key exam tips (from the guide):
  • Always include PT goals and specific techniques in every answer - this differentiates a BPT answer
  • Use subheadings with bullet points for 15-mark answers
  • Draw labelled diagrams for fractures, deformities, and anatomy
  • Always mention X-ray, MRI, and relevant blood tests in investigations
  • For 2-mark answers: 2-3 crisp lines only, no padding
