What happens during a cubital tunnel decompression operation?

Cubital tunnel decompression surgery aims to relieve pressure on the ulnar nerve. An incision is made over the cubital tunnel, and the ulnar nerve is manually decompressed. Sometimes this doesn’t work right away, and the surgeon has to move the nerve to a new position, or flatten the bony prominence so the nerve can slide smoothly backwards and forwards. Recovery from the operation takes around 3 months, but in some cases, you may not get complete sensation and muscle strength back.
