Neuroplasty and/or transposition of the ulnar nerve at the wrist is a surgical procedure aimed at alleviating nerve entrapment and compression. The ulnar nerve, which is a critical nerve in the arm, travels from the collarbone down the inner side of the arm, passing through the cubital tunnel at the elbow and continuing through Guyon's canal at the wrist before reaching the hand. This procedure is particularly relevant for patients experiencing symptoms related to ulnar nerve compression, such as pain, numbness, or weakness in the hand and fingers. The surgical intervention involves making a zigzag incision at the base of the palm on the little finger side, extending over the wrist, to access the ulnar nerve. The surgeon then incises the roof of Guyon's canal and meticulously divides any scar tissue, adhesions, or other structures that may be compressing the nerve. The goal is to free the ulnar nerve from any surrounding tissue that may be causing entrapment, thereby restoring normal function and alleviating symptoms. Following the procedure, the soft tissues are closed in layers to promote healing and recovery.
