Movements of the Anterior Forearm | Abduct/ adduct wrist; Flex wrist; Flex MCP/ IP joints; Pronate forearm |
Movements of the Posterior Forearm | Abduct/ adduct wrist; Extend wrist; Extend MCP/ IP joints; Supinate forearm |
Three compartments of hand muscles | Thenar (thumb); Hypothenar (little finger); Central (everything else) |
Compression of median n. (as in carpal tunnel syndrome) causes: | atrophy of thenar eminence |
Extensors digitorum & digiti minimi form what on dorsal digit surface? | Extensor hoods |
Palmaris longus is absent in how many people? | 15% |
Flexor digitorum tendons: tendon of deeper muscle will: | cross more joints |
Tendons of FDP pass through: | gap in FDS to reach distal phalanx |
Flexor digitorum tendons: held tightly to digits with: | fibrous digital sheaths |
Flexor digitorum tendons: Lubrication of tendons provided by: | synovial sheaths |
Carpal tunnel: roof = | flexor retinaculum |
Carpal tunnel: Walls/ floor = | carpal arch |
Carpal tunnel contains 10 structures: | 4 tendons FDS; 4 tendons FDP; 1 tendon FPL; Median n. |
Extensor retinaculum: function | Holds tendons of extensors in place |
Extensor retinaculum = | tendons surrounded by synovial sheaths |
Common site of synovial (ganglionic) cysts | Extensor retinaculum |
Medial epicondylitis is due to: | overpronation (golfers elbow) |
Lateral epicondylitis is due to: | oversupination (tennis elbow) |
