| + | Definition: abnormal alignment, during motion under normal/ physiologic loads | ||
| + | |||
| + | Causes: trauma (acute/ cumulative); | ||
| + | |||
| + | PPI: | ||
| + | * SLD vs scaphoid fracture (radial deviation) <- wrist extension | ||
| + | * Herzberg: Stage I vs II (Mayfield 4) | ||
| + | * Greater vs lesser arc injuries | ||
| + | |||
| + | VISI vs DISI | ||
| + | |||
| + | CID, CIND, CIC, CIA | ||
| + | |||
| + | === SLD=== | ||
| + | * dorsal strongest, volar for rotation | ||
| + | * hyperextended wrist in ulnar deviation | ||
| + | * secondary stabilizers: | ||
| + | |||
| + | === LTD === | ||
| + | * FOOSH: wrist extension and radial deviation --> hypothenar & pisiform --> shears Tq | ||
| + | * LTD more stable pattern compared to SLD | ||
| + | * LT: palmar stronger | ||
| + | * Secondary: dorsal RTq, scaphoTq ligament | ||
| + | |||
| + | |||
| + | === Scaphoid fx === | ||
| + | * humpback deformity --> DISI | ||
| + | |||
| + | === CIND=== | ||
| + | * CIND-VISI or palmar CIND - 'volar sag', 'catch up clunk' | ||
| + | * CIND-DISI or dorsal CIND - young hypermobile, | ||
| + | * Combined CIND | ||
| + | * dorsal capitate displacement test | ||
| + | * traction | ||
| + | * flexion | ||
| + | * ulnar deviation | ||
| + | * dorsal pressure on scaphoid | ||
| + | |||
| + | ===CIC=== | ||
| + | * perilunate dislocations | ||
| + | * axial dislocations | ||
| + | * AP crush: associated with soft tissue, neurovascular problems | ||
| + | * flexor retinaculum torn, flattening of the arch | ||
| + | * axial ulnar, axial radial | ||
