Three arches: medial & lateral longitudinal, and transverse (anterior/posterior). Keystone bones: talus (medial longitudinal), cuboid (lateral), intermediate cuneiform (transverse)...
General | 👁 6 | 2 weeks agoOrigin: supraspinous fossa; insertion: superior facet of greater tuberosity; innervation: suprascapular nerve (C5–6). Action: initiates abduction, contributes to humeral head depre...
General | 👁 2 | 2 weeks agoThickened lateral fascia lata from iliac crest to Gerdy’s tubercle; receives fibers from TFL and gluteus maximus. Functions: lateral knee stabilization, assists hip abduction and k...
General | 👁 3 | 2 weeks agoTillaux: Anterolateral epiphyseal avulsion (SH-III) during asymmetric physeal closure — intra-articular; >2 mm step needs fixation. Triplane: Multi-planar SH-IV variant (sagittal e...
Trauma | 👁 4 | 2 weeks agoType I: Anterior radial head dislocation with anterior angulated ulnar fracture — most common in children. Type II: Posterior/posterolateral dislocation; Type III: Lateral/anterior...
Trauma | 👁 7 | 2 weeks agoType I: Nondisplaced — anterior humeral line intersects capitellum; treat in long arm cast. Type II: Displaced with posterior cortex intact (hinge) — often closed reduction & pinni...
Trauma | 👁 4 | 2 weeks agoMilch Type I: Fracture line lateral to trochlear groove (through capitellum–trochlear junction) — more stable. Milch Type II: Fracture line extends into trochlea — less stable (ris...
Trauma | 👁 3 | 2 weeks agoO’Brien Angulation: I (60°). Displacement/translation also matters; >3 mm or severe angulation predicts need for reduction/fixation. Metaizeau (elastic stable intramedullary nailin...
Trauma | 👁 9 | 2 weeks agoType I: Transepiphyseal (with/without dislocation) — highest AVN risk. Type II: Transcervical (through the neck). Type III: Cervicotrochanteric (basicervical). Type IV: Intertrocha...
Trauma | 👁 5 | 2 weeks agoType I: Minimally displaced avulsion. Type II: Hinge of posterior fibers intact (anterior lift) — may reduce closed; fixation if interposed tissue. Type III: Completely displaced f...
Trauma | 👁 3 | 2 weeks agoGrade 0: minimal; 1: superficial abrasions/contusions; 2: deep contaminated abrasions, muscle contusion; 3: extensive crush, compartment risk. Higher grades predict complications a...
Trauma | 👁 3 | 2 weeks agoPosterior elbow dislocation + radial head fracture + coronoid tip fracture. Requires concentric reduction, radial head fixation/replacement, coronoid/LCCL repair.
