Gartland Classification — Supracondylar Humerus (Extension Type)

Type I: Nondisplaced — anterior humeral line intersects capitellum; treat in long arm cast. Type II: Displaced with posterior cortex intact (hinge) — often closed reduction & pinning (CRPP). Type III: Completely displaced with no cortical contact — unstable; CRPP with two or three pins. Type IV (Leitch): Multidirectional instability (both cortices incompetent) — unstable under fluoroscopy; pin spread critical.
