humeroulnar joint
- humerus and ulna - trochlear notch and trochlea of humerus - important for flexion and extension
61

63
ulnar (med) & radial (lat) collateral ligaments of elbow

damage to median nerve-> no flexion of thumb, middle, and index finger, no MP and IP joint flexion
67
flexor retinaculum
- anterior of wrist - band that runs from trapezius and scaphoid to hamate and pisiform - holds flexors in place, prevents bowing out - median nerve runs deep - 9 tendens-> 4 FDS, 4FDP, 1 flexor pollicis longus - root of carpal tunnel
68
ulnar (med) and radial (lat) collateral ligaments of wrist
ulnar: AB radial: AD of wrist -keep carpal tunnel bones in place
69
anatomical snuff box
- triangle at root of thumb - tendons of AB pollicis longus (lat), extensor pollicis brevis (lat), extensor pollicis longus (med) - pain inside snuff box-> fracture to scaphoid (can't see in x rays) - radial artery deep to snuff box
70
extensor retinaculum
- wrist tendon | - keeps extensor tendons in alignment
71
cubital fossa
- "elbow", anterior, communicator between forearm and arm - made of brachioradialis (lat border), pronator trees (med border), horizontal like through epicondyles - deep- biceps brachii tendon and aponerosis, brachial artery, median nerve - superficial- cephalic vein, basilic vein, median cubital vein
72
golfer's elbow
- aka medial epicondylitis | - flexor tendons enflamed and pull away from medial epicondyle
73
tennis elbow
- aka lateral epicondylitis | - muscle pulls away from lateral epicondyle due to inflammation
74
wrist drop
high lesion of radial nerve-> loss of extension of wrist (still have flexion)
75
carpel tunnel syndrome
inflammation of 9 flexor retinaculum tendons and compression of median nerve - pain w finger and wrist flexion/extension - burning sensation and numbness of palmar radial 3 1/2 digits - weakness and atrophy of thenar muscles - surgery to release pressure of flexor retinaculum --> careful not to cut median nerve
