I guess this is for medical students or doctors.?

Question

please whats the side effect if someone has an ulner nerve injury and still has not done the surgery on the nerves after 11 yrs but has the flesh stitched up and has partial feelings on some parts of the fingers affected?

Answer 1

In some cases there will be no residual deficit. However, the ulnar nerve supplies:

- sensation of the little finger and half of the ring finger
- motor signals to the small muscles of the hand

and if there has been a laceration or an old injury that is impairing function there could be weakness spreading fingers apart or holding them tight together.

If the injury is high up on the arm there may be weakness of flexing the wrist or cupping the hand.
