Cubital Tunnel Syndrome
Cubital Tunnel Syndrome is a compression or stretch of the ulnar nerve as it passes through the cubital tunnel located on the medial (inside) aspect of the elbow. Compression of the ulnar nerve may be due to hypertrophy (enlargement) of the flexor carpi ulnaris muscle (muscle located on the inside of the forearm) or due to osteophytes (bony outgrowths) within the cubital tunnel. Irritation of the ulnar nerve due to stretch usually follows repetitive throwing sports where the elbow is repeatedly placed in a position of full flexion and the wrist in a position of full extension, as would happen in overarm throwing. Symptoms of Cubital Tunnel Syndrome include pain in the medial (inside) forearm with numbness, pins and needles and/or pain that travels down the forearm into the ring and little finger.
