- Vascular Problems of the Wrist and Hand:
- traumatic thrombosis of superficial palmar arch of ulnar artery resulting from repetitive use of hand as hammer;
- in this maneuver, maximum force of the blow occurs over hook hamate bone, stie of superifical palmar arch of ulnar artery;
- ulnar artery appears to be most vulnerable in distal portion of Guyon's canal, where protective capabilities of palmaris brevis muscle
are least effective;
- most common presenting symptom w/ ulnar arterry thrombosis is pain;
- pts also suffer from cold intolerence (pain w/ exposure to cold) and pain associated with repetitive activity;
- pain at night and w/ rest;
- frequently have dependent rubor, ulceration of fingertips, or gangrene
