Grade 0: minimal; 1: superficial abrasions/contusions; 2: deep contaminated abrasions, muscle contusion; 3: extensive crush, compartment risk. Higher...
Posterior elbow dislocation + radial head fracture + coronoid tip fracture. Requires concentric reduction, radial head fixation/replacement, coronoid/...
Medial hinge disruption >2 mm, anatomic neck fracture, head-splitting → high AVN risk. Assists decision towards arthroplasty in ischemic patterns.
Type I: Through physis only (slip) — good prognosis; often in younger children. Type II: Through physis and metaphysis (Thurston–Holland fragment) — m...
Morphology (compression 1, burst 2, translation/rotation 3, distraction 4), Posterior ligamentous complex integrity (intact 0, indeterminate 2, disrup...
I: 10 cm/high-energy or extensive damage. IIIa: adequate coverage; IIIb: periosteal stripping, needs flap; IIIc: arterial injury requiring repair. Hig...
Compression: anterior column only — usually stable. Burst: anterior + middle columns — unstable, canal compromise risk. Flexion-distraction (Chance):...
Type A (compression): A1 wedge, A2 split, A3 incomplete burst, A4 complete burst. Type B (tension band): B1 posterior through bone/ligament, B2 poster...
Type I: tip avulsion (rare, stable). Type II: base of dens (common, unstable, high nonunion). Type III: into C2 body (better healing).
Type I: 3 mm and/or angulation (disc injury) — traction/halo or surgery. Type IIa: flexion–distraction variant (marked angulation). Type III: with C2–...
