A hand imitating an ulnar claw. The metacarpophalangeal joints of the 4th and 5th fingers are extended and the Interphalangeal joints of the same fingers are flexed.. An ulnar claw, also known as claw hand or Spinster’s Claw, is a deformity or an abnormal attitude of the hand that develops due to ulnar nerve damage causing paralysis of the lumbricals.
Some fractures, however, cannot be held in a satisfactory position by this method, and require some additional form of fixation. This is the usual situation with all displaced fractures of the first metacarpal and of the proximal phalanges of the hand, and of about two thirds of fractures of the distal end of the radius. Percutaneous pinning is ...
Especially involving compression at the wrist, such as in CTS, it is possible to recover without treatment. Physical therapy can help build muscle strength and braces or splints help recover. [18] In pronator teres syndrome, specifically, immobilization of the elbow and mobility exercise within a pain-free range are initially prescribed.
Gamekeeper's thumb and skier's thumb are two similar conditions, both of which involve insufficiency of the ulnar collateral ligament (UCL) of the thumb. The chief difference between these two conditions is that skier's thumb is generally considered to be an acute condition acquired after a fall or similar abduction injury to the metacarpophalangeal (MCP) joint of the thumb, whereas gamekeeper ...
Hand and wrist injuries are reported to account for fifteen to twenty percent of emergency room injuries, and metacarpal fractures represent a significant number of those injuries. Hand injuries of this sort are most prevalent among fifteen- to thirty-five-year-old males, and the fifth metacarpal is the one most commonly affected. [12]
The abductor digiti minimi arises from the pisiform bone, the pisohamate ligament, and the flexor retinaculum. [1]Its distal tendon ends in three slips that are inserted into the ulnopalmar margin of the proximal phalanx, the palmar plate of the metacarpophalangeal joint, and the sesamoid bone when present.

The ulnar nerve originates from the C8-T1 nerve roots (and occasionally carries C7 fibers which arise from the lateral cord), [5] [6] which then form part of the medial cord of the brachial plexus, and descends medial to the brachial artery, up until the insertion point of coracobrachialis muscle (middle 5 cm over the medial border of the humerus).
