Here are comprehensive clinical notes on all 12 conditions, sourced from authoritative medical and surgical textbooks:

ORTHOPAEDIC CONDITIONS


1. Fracture of Clavicle

Definition: Break in the clavicle (collar bone), the S-shaped strut connecting the shoulder girdle to the trunk at the sternum (medially) and acromion (laterally).
Classification (by location):
  • Middle third - most common (~80%)
  • Distal third - 3 subtypes (Neer classification):
    • Type I: fracture distal to coracoclavicular ligaments (ligaments intact)
    • Type IIa: fracture medial to ligaments (proximal fragment displaced superiorly)
    • Type IIb: both ligaments disrupted
    • Type III: involves AC joint
  • Medial third - least common
Mechanism: Direct blow to the shoulder, causing buckling of the clavicle. The midportion is most vulnerable because it has no muscular or ligamentous attachments.
Clinical Features:
  • Swelling, deformity, and tenderness over the clavicle
  • Arm slumped inward and downward
  • Restricted range of motion
  • Palpable fracture ends; crepitus may be present
Associated Injuries: Rib fractures, brachial plexus injury, pneumothorax, subclavian vessel injury. Always assess AC and SC joints.
Investigations:
  • Standard shoulder/clavicle X-ray (AP)
  • 45-degree cephalad tilt view if standard X-ray inconclusive
  • CT scan for complex/comminuted fractures
Treatment:
  • Nonoperative (most middle-third fractures): Sling or figure-of-eight brace for 4-8 weeks. Begin elbow ROM immediately; shoulder ROM in 3-5 days as pain allows.
  • Operative indications: Open fractures, neurovascular injury, skin tenting, displacement >100%, shortening >2 cm, comminution, athlete, cosmetic concern. Treated by plate and screw fixation or intramedullary device.
  • Distal type II fractures typically require surgical fixation due to high nonunion risk.
Complications: Nonunion, malunion, thoracic outlet syndrome, brachial plexus palsy.
  • Tintinalli's Emergency Medicine, p. 1864; Rockwood and Green's Fractures in Adults

2. Fracture of Humerus

Types:
  1. Proximal humerus fracture (surgical/anatomical neck, greater tuberosity)
  2. Shaft fracture
  3. Distal humerus fracture (supracondylar, intercondylar)
Proximal Humerus Fractures:
  • Common in elderly (osteoporosis)
  • Neer Classification: based on displacement of 4 segments (head, shaft, greater tuberosity, lesser tuberosity)
  • Signs: Swelling, bruising, pain at shoulder; loss of normal relationship between medial epicondyle and greater tuberosity suggests fracture/dislocation
  • Assessment: Palpate greater tuberosity - its disappearance indicates dislocation; local bony tenderness at surgical neck = fracture neck humerus
  • Bimanual palpation through deltoid and axilla is key on examination
Shaft Fracture:
  • Often midshaft
  • Radial nerve injury is a classic complication (runs in the spiral groove) - causes wrist drop
  • "Holstein-Lewis" fracture - radial nerve trapped at distal 1/3
Distal Humerus / Supracondylar:
  • Common in children (hyperextension injury)
  • Risk of anterior interosseous nerve and brachial artery injury
  • Late complication: tardy ulnar palsy from malunited supracondylar fracture with cubitus valgus
Investigations: X-ray AP and lateral; CT for complex fractures
Treatment:
  • Undisplaced: Collar-and-cuff sling, early mobilization
  • Displaced proximal fractures: ORIF or hemiarthroplasty/reverse TSA in elderly
  • Shaft: Conservative (U-slab/functional brace) or IM nail/plate for displaced
  • Supracondylar in children: Closed reduction and percutaneous K-wires (urgent if neurovascular compromise)
Complications: Radial nerve palsy, malunion, avascular necrosis (anatomical neck), myositis ossificans, Volkmann's ischaemic contracture (supracondylar).
  • S. Das - A Manual on Clinical Surgery, 13th ed.; Rockwood and Green's Fractures in Adults

3. Osteomyelitis

Definition: Infection of bone, most commonly by bacteria.
Classification:
  • Haematogenous (most common in children) - spreads via blood
  • Contiguous (secondary) - from adjacent soft tissue infection or open fracture
  • Chronic - persistent infection with dead bone (sequestrum)
Causative Organism: Staphylococcus aureus is the most common in all age groups. Salmonella in sickle cell disease. Pseudomonas in IV drug users/puncture wounds.
Sites: Long bones (distal femur, proximal tibia, proximal humerus) in children; vertebrae, jaw, and diabetic foot in adults.
Jaw Osteomyelitis (3 types - relevant to dental students):
  1. Acute - seen in infants after febrile illness (measles, scarlet fever); mandible or maxilla affected; swelling, redness, pus from nostril (if maxilla)
  2. Subacute (most common) - adults; from apical dental infection, alveolar abscess, or tooth extraction with poor general condition; pain, swelling, tenderness, bony irregularity; numbness of chin (mental nerve compression); X-ray shows changes after 3 weeks minimum
  3. Chronic - follows dental infection/fractures; months after original illness; X-ray shows local osteitis and sequestrum
Clinical Features (long bones):
  • Acute: Fever, malaise, local bone pain, warmth, tenderness, reluctance to move limb
  • Chronic: Discharging sinus, sequestrum, involucrum
Investigations:
  • Blood: raised WBC, ESR, CRP; blood cultures
  • X-ray: changes appear 10-21 days later
  • MRI: earliest and most sensitive (shows within 3-5 days)
  • Bone scan (Tc-99m): highly sensitive
Treatment:
  • Acute: IV antibiotics (anti-staphylococcal - flucloxacillin) for 4-6 weeks; surgical drainage if abscess
  • Chronic: Sequestrectomy + saucerization + long-term antibiotics; hyperbaric oxygen as adjunct
  • S. Das - A Manual on Clinical Surgery, 13th ed.; Goldman-Cecil Medicine

4. Tennis Elbow (Lateral Epicondylitis)

Definition: Degenerative tendinopathy at the origin of the extensor muscles on the lateral epicondyle of the humerus, mainly the extensor carpi radialis brevis (ECRB). The term "epicondylitis" is a misnomer - it is not truly inflammatory but rather a degenerative "tendinosis."
Pathology: Microscopic rupture and incomplete tendinous repair at the ECRB origin on the lateral epicondyle, causing angiofibroblastic degeneration (neovascularization, disorganized collagen).
Cause: Repetitive microtrauma from wrist extension, flexion, supination, or pronation - common in tennis players, gardeners, carpenters, and office workers.
Clinical Features:
  • Pain over lateral humeral epicondyle, aggravated by activity
  • Tenderness at the lateral epicondyle
  • Pain provoked by: wrist extension against resistance, extension of the middle finger against resistance (Maudsley's test)
  • Grip strength reduced
Investigations:
  • Clinical diagnosis in most cases
  • Ultrasound: low-reflective thickened tendon, neovascularization on Doppler
  • MRI if diagnosis uncertain
Treatment:
  • Conservative (first-line): Rest, physiotherapy, counterforce brace (clasp), NSAIDs
  • Corticosteroid injection: Short-term benefit; high recurrence rate
  • Platelet-rich plasma (PRP): Emerging evidence for longer-term relief
  • Surgery: Open or arthroscopic release of ECRB; for refractory cases (>6-12 months). Results: ~85% good to excellent.
  • Roberts and Hedges' Clinical Procedures in Emergency Medicine; Campbell's Operative Orthopaedics, 15th ed.

5. Frozen Shoulder (Adhesive Capsulitis)

Definition: Contracted, thickened joint capsule drawn tightly around the humeral head with synovial inflammation and reactive capsular fibrosis, resulting in painful global restriction of shoulder movement.
Epidemiology: Incidence ~2% in general population. Age 40-70 years. Female predominance (70%). Bilateral in 20-30% (50% in diabetics). Rarely recurs in the same shoulder.
Risk Factors / Associations:
  • Diabetes mellitus (5x increased risk; insulin-dependent patients especially)
  • Age >49 years, female sex
  • Prolonged immobilization (any cause)
  • Cervical disc disease
  • Hyperthyroidism, hypothyroidism
  • Hyperlipidemia
  • Previous stroke, MI, trauma
  • Autoimmune disease
Pathology: Synovial inflammation → fibroblast proliferation → capsular contracture. Neoangiogenesis and neo-innervation within the capsule drive severe pain.
Stages (Neviaser):
  1. Freezing (0-3 months): Gradual onset of pain; begins to lose ROM
  2. Frozen (3-12 months): Pain lessens but stiffness worsens; global ROM restriction
  3. Thawing (12-24 months): Gradual return of movement; self-limiting in most
Clinical Features:
  • Global restriction of shoulder movement (all planes), especially external rotation (hallmark)
  • Pain, worse at night
  • Axillary fold thickening on examination
  • Arthrogram: reduced capsular volume (normally 30 mL, reduced to <10 mL)
Investigations:
  • X-ray: usually normal (excludes other pathology)
  • MRI: capsular thickening, especially at rotator interval
  • Arthrogram: reduced joint volume (diagnostic)
Treatment:
  • Phase 1 (Freezing): NSAIDs, intra-articular steroid injection (significant short-term benefit), physiotherapy (gentle ROM)
  • Phase 2 (Frozen): Physiotherapy (stretching), hydrodilatation (distension arthrography)
  • Phase 3 / Refractory: Manipulation under anesthesia (MUA); arthroscopic capsular release
  • Campbell's Operative Orthopaedics, 15th ed.; Firestein & Kelley's Textbook of Rheumatology

6. Rotator Cuff Tear (RCT)

Definition: A tear in one or more of the four rotator cuff tendons - supraspinatus, infraspinatus, teres minor, or subscapularis. Supraspinatus is most commonly torn.
Classification:
  • Partial thickness: Involves only part of the tendon; further subdivided into articular-side, bursal-side, and intratendinous
  • Full thickness (complete): Extends through the entire thickness; may be small (<1 cm), medium (1-3 cm), large (3-5 cm), or massive (>5 cm or involving 2+ tendons)
Etiology:
  • Degenerative (most common, age-related, intrinsic tendon degeneration)
  • Traumatic (acute tear from dislocation, fall on outstretched hand)
  • Impingement (extrinsic - acromion compresses supraspinatus)
  • If a patient has a symptomatic full-thickness RCT in one shoulder, they have a ~50% chance of asymptomatic full-thickness tear in the contralateral shoulder
Clinical Features:
  • Pain at rest and with overhead activity
  • Night pain (hallmark)
  • Weakness of abduction and external rotation
  • Tenderness just below the acromion (supraspinatus insertion at greater tuberosity)
  • Positive impingement signs (Neer, Hawkins-Kennedy)
  • Positive drop arm test (full-thickness tear)
  • External rotation lag sign (infraspinatus tear)
Investigations:
  • MRI (with or without arthrogram): Gold standard for characterizing tear size, location, tendon retraction, and muscle atrophy
  • Ultrasound: dynamic assessment, good for full-thickness tears
  • X-ray: may show superior migration of humeral head in massive chronic tears
Treatment:
  • Conservative (partial/small tears): Physiotherapy, NSAIDs, subacromial corticosteroid injection
  • Surgical (large/full-thickness, failed conservative):
    • Arthroscopic or open rotator cuff repair
    • Tendon-to-bone repair with anchors
    • Reverse total shoulder arthroplasty (for massive irreparable tears with arthropathy - "cuff tear arthropathy")
  • Outcome: best if repaired before significant muscle atrophy and fatty degeneration
  • Campbell's Operative Orthopaedics, 15th ed.; Firestein & Kelley's Textbook of Rheumatology

DENTAL/ORAL CONDITIONS


7. Epulis

Definition: The word "epulis" means "upon the gum." It refers to any benign lesion situated on the gingiva (majority are reactive processes).
Types:
TypeFeatures
Granulomatous (fibrous) epulisCommonest; slow-growing, firm, red, sessile or pedunculated; arises from periodontal membrane; benign but recurs if root not excised
Sarcomatous epulisRapid growth, soft, bluish-red, bleeds easily
Myelomatous epulis (periosteal osteoclastoma)Sessile, soft, lobulated, purplish; egg-shell crackling; soap-bubble X-ray appearance; may undergo malignant change
Carcinomatous epulisInfiltrating epithelioma at gum or tooth socket; invades bone, ulcerates; lymph node enlargement always present
Giant cell epulis (peripheral giant cell granuloma)Solitary, bluish-red, 10-20 mm; between deciduous bicuspids/incisors; can be induced by dental implants; histologically resembles giant cell tumor
Congenital epulisPresent at birth; usually on maxillary gingiva; a form of granular cell tumor
Epulis gravidarumIn pregnancy; pyogenic granuloma subtype
Treatment: Surgical excision with the base/root; if root not excised fully, recurrence is common.
  • S. Das - A Manual on Clinical Surgery, 13th ed.; Andrews' Diseases of the Skin

8. Dental Caries

Definition: Progressive bacterial destruction of the tooth substance (enamel, then dentine, then pulp) mediated by acid produced from fermentable carbohydrates by oral bacteria.
Key Organism: Streptococcus mutans (primary); Lactobacillus spp. (secondary progression)
Pathogenesis:
  1. Bacteria (especially S. mutans) colonize the tooth surface forming dental plaque (biofilm)
  2. Bacteria ferment dietary sugars → produce lactic acid
  3. Acid dissolves hydroxyapatite → demineralization of enamel
  4. Progressive destruction: enamel → dentine → pulp (pulpitis) → periapical abscess → dental cyst
Risk Factors:
  • High refined sugar diet
  • Poor oral hygiene
  • Low fluoride exposure
  • Dry mouth (xerostomia)
  • Bottle-feeding at night in infants (nursing bottle caries)
Clinical Features (stages):
  1. White spot lesion (earliest - demineralization, reversible)
  2. Cavitation of enamel
  3. Dentine involvement - sensitivity to temperature/sweets
  4. Pulpal involvement - spontaneous throbbing pain
  5. Periapical abscess - severe pain, swelling, fever
Prevention:
  • Fluoride (most effective method): strengthens enamel (fluorapatite), inhibits bacterial metabolism; via fluoridated water, toothpaste, topical gel
  • Dietary modification, oral hygiene, fissure sealants, regular dental checks
Treatment:
  • Early (white spot): Fluoride remineralization
  • Cavitated: Excavation and filling (composite/amalgam)
  • Pulpal involvement: Root canal treatment (RCT)
  • Irreversible pulpitis/periapical abscess: Extraction or RCT
  • Park's Textbook of Preventive and Social Medicine; Katzung's Basic and Clinical Pharmacology, 16th ed.

9. Dental Cyst

Two main types:

A. Dental Cyst (Radicular / Periapical Cyst)

  • Association: Always associated with a carious (non-vital) tooth
  • Pathogenesis: Dental caries → pulp necrosis → periapical infection → stimulates epithelial cell rests of Malassez → cyst formation at the apex
  • Site: Upper jaw more common (tends to expand into maxillary sinus)
  • Features: Slow-growing swelling; egg-shell crackling if bone thinned; fluctuation if bone destroyed; cyst fluid is clear with cholesterol crystals; typically asymptomatic unless infected
  • X-ray: Well-defined periapical radiolucency surrounding apex of a carious tooth
  • Treatment: Root canal treatment (RCT) of the tooth ± apicectomy; or extraction + curettage of cyst

B. Dentigerous Cyst (Follicular Odontome)

  • Association: Always associated with the crown of an unerupted permanent tooth
  • Pathogenesis: Develops from reduced enamel epithelium surrounding the crown of an unerupted tooth; accumulation of fluid between crown and enamel epithelium
  • Common tooth: Lower 3rd molar (wisdom tooth), upper canine
  • Features: Enlarges slowly with bone resorption; may involve entire body of mandible including ramus if untreated; egg-shell crackling; fluctuation
  • X-ray: Well-defined radiolucency surrounding the crown of an unerupted tooth (pericoronal)
  • Treatment: Enucleation of cyst + extraction of unerupted tooth (or marsupialization for large cysts)
  • S. Das - A Manual on Clinical Surgery, 13th ed.; Robbins, Cotran & Kumar Pathologic Basis of Disease

10. Dental Fistula (Oral/Dental Sinus)

Definition: An abnormal tract/channel that drains pus from a dental (periapical) abscess to the surface, either intraorally (gingival sinus) or extraorally (cutaneous sinus on the face/chin).
Pathogenesis: Dental caries → pulp necrosis → periapical abscess → pus tracks through bone → fistula/sinus tract forms to provide drainage
Types:
  • Intraoral (parulis/gum boil): Opens on the gingival mucosa near the offending tooth. Appears as a small nodule with a central opening that may exude pus.
  • Extraoral (cutaneous): Rare; pus tracks through facial tissue to open on skin
    • Lower incisor abscesses → median mental sinus (midline chin sinus)
    • Submandibular or submasseteric abscess from lower molars
Clinical Features:
  • Painless (or minimally painful) small opening in the gum or skin
  • Purulent discharge from the sinus
  • The offending tooth is usually non-vital (does not respond to cold/EPT)
  • X-ray: periapical radiolucency at root apex
Treatment:
  • Treat the underlying cause: RCT or extraction of the offending tooth
  • Once the source is eliminated, the fistula/sinus closes spontaneously
  • No need for surgical excision of the tract alone
  • S. Das - A Manual on Clinical Surgery, 13th ed.

11. Gingivitis

Definition: Inflammation of the gingiva (gums) without loss of supporting bone or periodontal attachment. It is the most common form of periodontal disease and is reversible.
Etiology:
  • Plaque-induced (most common): Dental plaque (bacterial biofilm) accumulation at the gingival margin triggers the inflammatory response
  • Modified by systemic factors: Hormonal (puberty, pregnancy - epulis gravidarum), medications (phenytoin → gingival hyperplasia; nifedipine; cyclosporine), blood dyscrasias (leukaemia), vitamin C deficiency (scurvy - scorbutic gingivitis), diabetes mellitus
  • Non-plaque induced: Viral (herpetic gingivostomatitis), bacterial (NUG/ANUG - necrotizing ulcerative gingivitis), fungal
Acute Necrotizing Ulcerative Gingivitis (ANUG/"Trench Mouth"):
  • Organisms: Fusobacterium, Treponema, Bacteroides
  • Features: Punched-out ulcers with grayish pseudomembrane at interdental papillae, metallic taste, fetid halitosis, pain, bleeding, fever
  • Predisposed by: stress, HIV/immunosuppression, malnutrition
Clinical Features (Chronic Plaque Gingivitis):
  • Redness, swelling, bleeding of gums (especially on brushing - BOP = bleeding on probing)
  • Gum appears dusky red rather than pink
  • Loss of normal stippled texture
  • Gingival crevice deepening (pseudopocket)
  • No bone loss on X-ray (distinguishes from periodontitis)
Key Distinction: Gingivitis = no attachment loss (reversible); Periodontitis = attachment loss + bone loss (partially irreversible)
Treatment:
  • Oral hygiene instruction (brushing, flossing)
  • Professional scaling and root planing (remove calculus/plaque)
  • Chlorhexidine mouthwash (adjunct)
  • Address local/systemic factors
  • ANUG: Metronidazole + debridement + oral hygiene
  • Park's Textbook of Preventive and Social Medicine; S. Das - A Manual on Clinical Surgery, 13th ed.

12. Ranula

Definition: A fluid-filled swelling (extravasation pseudocyst) arising from the sublingual salivary gland, located in the floor of the mouth. The name comes from "rana" (frog) - the swelling resembles a frog's underbelly.
Types:
Simple (Intraoral)Plunging (Cervical)
LocationFloor of mouth onlyExtends through/around mylohyoid into neck
MechanismDuctal obstruction/extravasationMucus extends beyond floor of mouth into infra-mylohyoid space
FrequencyMore commonLess common
Aetiology:
  • Obstruction or trauma to sublingual gland or duct (spontaneous or post-surgical)
  • May be congenital
Clinical Features:
  • Smooth, dome-shaped swelling in floor of mouth
  • Characteristic bluish translucent appearance
  • If large: may elevate tongue, causing difficulty swallowing, speaking, chewing, or breathing
  • Plunging ranula: presents as a soft neck mass, may mimic lymphatic malformation
Investigations:
  • Simple intraoral ranula: clinical diagnosis, no imaging needed
  • Plunging/uncertain/post-surgical: MRI preferred (best delineates extent)
  • FNA: can aid diagnosis; fluid characteristically clear and mucoid
Histology: Ranula is contained by loose connective tissue (no epithelial lining = pseudocyst); lymphatic malformation has a simple epithelial lining.
Treatment:
  • Simple aspiration alone: very high recurrence
  • Marsupialization of plunging ranula: 80% recurrence - inadequate alone
  • Gold standard: Excision of ranula + sublingual gland (recurrence rate only 3.6%)
  • Approach: transoral (intraoral lesions); transcervical (neck lesions)
  • Preserve the lingual nerve (lies in close proximity)
  • Alternative: OK-432 (sclerosing agent injection), laser excision for intraoral type
  • Scott-Brown's Otorhinolaryngology Head & Neck Surgery; Cummings Otolaryngology

OriginCell rests of Malassez at apexReduced enamel epithelium
X-rayPeriapical radiolucencyPericoronal radiolucency
FluidClear + cholesterol crystalsStraw-coloured fluid
TreatmentRCT ± apicectomyEnucleation + extraction
  • Both can cause egg-shell crackling; enlarge slowly by bone resorption

10. Dental Fistula (Dental Sinus)

  • Definition: Sinus tract draining pus from a periapical abscess to the surface
  • Types:
    • Intraoral (parulis/gum boil): Opens on gum near offending tooth
    • Extraoral (cutaneous): e.g., Median mental sinus (from lower incisor abscess, drains at chin midline)
  • Features: Painless/mild pain; purulent discharge; non-vital tooth; periapical X-ray shows radiolucency
  • Treatment: RCT or extraction of offending tooth → fistula closes spontaneously (no need to excise the tract)

  • Definition: Gum inflammation WITHOUT bone/attachment loss (reversible)
  • Cause: Dental plaque (most common); also systemic (pregnancy, diabetes, phenytoin, leukaemia, scurvy)
  • Features: Red, swollen, bleeding gums (bleeding on probing - BOP); no bone loss on X-ray
  • ANUG (Acute Necrotizing Ulcerative Gingivitis): Punched-out ulcers at interdental papillae, fetid halitosis, metallic taste; organisms: Fusobacterium + Treponema; treat with metronidazole
  • Key distinction: Gingivitis = no attachment loss; Periodontitis = attachment + bone loss
  • Treatment: Scaling, oral hygiene, chlorhexidine mouthwash

12. Ranula

  • Definition: Pseudocyst from sublingual salivary gland; floor of mouth swelling
  • Cause: Obstruction/trauma to sublingual gland or duct
  • Types:
    • Simple (intraoral): Floor of mouth only
