The surgical procedure in the course of the ulnar nerve groove consists in removing the cause of the nerve compression. It is usually a resection of degenerative bone lesions or connective tissue scars limiting the displacement of the ulnar nerve. The procedure requires a few centimeters incision along the nerve path in order to carefully work out the area of ​​the medial area of ​​the elbow. After the surgery, rehabilitation is necessary, which helps to restore the proper slide of the nerve and allows the weakened muscles of the upper limb to be strengthened.
