  3. Clinical Anatomy p.520 • Ligamentous Anatomy • Radial collateral ligament • limits ulnar deviation • taut in full flexion & extension • Ulnar collateral ligament • limits radial deviation • taut in full flexion & extension

  4. Clinical Anatomy p. 520 • Ligamentous Anatomy • Palmar radio-carpal ligament complex • limits wrist hyperextension • Dorsal radiocarpal ligament • only major dorsal ligament • limits wrist flexion • Palmar ulnocarpal ligament • limits hyperextension • Intercarpal ligaments • maintains alignment of carpals

  12. Functional Tests--p. 537 • Wrist ROM—Box 15-3, p. 538 • flexion>extension • ulnar deviation>radial deviation • Thumb ROM—p.543 • flexion/extension • abduction/adduction • opposition • Finger ROM—Box 15-4, p. 539 • flexion/extension • abduction/adduction

  13. Pathologies • Wrist/Hand • Fingers • Thumb

  14. Wrist/Hand Pathologies

Lunate dislocation--Table 15-10, p. 558 • History: • forced hyperextension (FOOSH) • hears/feels a “pop” • c/o pain at lateral wrist/hand • possible paresthesia • Observation: • (+) Murphy sign • obvious bulge dorsal or palmar • Palpation: • obvious deformity • possible crepitus • scaphoid fx? • Examination: • Palpation • x-ray to r/o scaphoid fx

  20. Wrist Fractures--p. 555 • History: • FOOSH injury • distal radius/ulna pain • heard/felt pop • immediate loss of function • Observation: • obvious deformity • Colles fx--distal radius moves dorsally • Smith’s fx--distal radius moves palmarly • Rapid swelling • Palpation: • obvious deformity • Probable crepitus • Examination: • x-ray referral
