ULNAR NERVE PARALYSIS

The ulnar nerve may be injured at the elbow, where it may be torn or lacerated when a fracture or dislocation takes place, later compressed by callus or scar tissue, or at the wrist, generally by direct injuries, such as cuts, or wounds. It may also be damaged in any part of its course by wounds or tumors.


Signs and Symptoms
  • paralysis
  • Claw-hand
  • Anaesthesia

If it is injured above the point where its branches to the forearm muscles are given off, the wrist should also be slightly flexed and the hand adducted.

The corrected position must be maintained throughout treatment
