Cubital Tunnel Release & Ulnar Nerve Transposition

Overview

In cubital tunnel syndrome, the ulnar nerve is compressed or stretched as it passes behind the inner elbow, causing numbness and tingling in the ring and small fingers and, over time, hand weakness.

When symptoms persist despite avoiding elbow bending and wearing a night splint, or when weakness develops, surgery can relieve pressure on the nerve. In a cubital tunnel release, the tissue roof over the nerve is opened. If the nerve snaps over the bone when the elbow bends, it can be moved to the front of the elbow (anterior transposition) so it is no longer stretched. Nerve release is also commonly performed alongside elbow arthritis or throwing-injury surgery.

Benefits

• Relieves pressure on the nerve
• Can improve numbness and prevent further weakness
• Outpatient surgery

Who is a Candidate?

Cubital Tunnel Release may be appropriate for patients who meet certain criteria. Ideal candidates include:

• Numbness lasting more than about six weeks despite nonsurgical treatment
• Weakness or muscle wasting in the hand
• A nerve that snaps over the inner elbow

Recovery & Rehabilitation

Most patients go home the same day and begin moving the elbow soon after surgery. Numbness often improves over weeks to months; severe, long-standing compression may not fully recover.
