Cubital Tunnel Syndrome


Cubital Tunnel

Cubital tunnel syndrome is a condition brought on by increased pressure on the ulnar nerve at the elbow. There is a bump of bone on the inner portion of the elbow (medial epicondyle) under which the ulnar nerve passes. This site is commonly called the “funny bone.” At this site, the ulnar nerve lies directly next to the bone and is susceptible to pressure.

When the pressure on the nerve becomes great enough to disturb the way the nerve works, then numbness, tingling and pain in the elbow, forearm, hand and/or fingers, and you may require cubital tunnel syndrome treatment.


  • Pain
  • Numbness
  • Tingling (most often occurs in the ring and little fingers)
  • Weakness while pinching, occasional clumsiness, and/or a tendency to drop things

Our Approach

The surgical tools Dr. Dustin Ray uses for endoscopic cubital tunnel release are miniscule and are inserted through a small 5mm incision at the elbow. In the single-portal technique, one small tube contains both the camera and an incising tool. This is a preferred type of cubital tunnel surgery.

Endoscopic Cubital Tunnel Release uses an endoscope, or a tiny camera, attached to a flexible tube. Dr. Dustin Ray guides it through a 5.0mm incision made at the elbow, allowing him a clear view of the nerve. The objective of this procedure is to relieve the pressure on the nerve to alleviate the pain, tingling and numbness in the fingers.

This procedure takes only 20 minutes, and most of our patients have recovered after just 7 days.
