How is cubital tunnel syndrome different from carpal tunnel syndrome?

Carpal tunnel syndrome and cubital tunnel syndrome are both ischemic neuropathies characterized by nerve compression that restricts blood supply to the nerve, leading to damage. While they share similar pathological mechanisms, they differ primarily in their anatomical location and the specific nerve affected:1

• Carpal Tunnel Syndrome: This condition involves the compression of the median nerve as it passes through the carpal tunnel at the wrist. It is frequently associated with repetitive stress, causing numbness, tingling, and pain in the hand, fingers, and thumb.21
• Cubital Tunnel Syndrome: This condition is a similar problem that specifically affects the ulnar nerve at the elbow.1

In both cases, the nerve narrows at the site of pressure, though the axon typically remains intact. If conservative treatments such as rest, bracing, or medication are ineffective, surgical intervention may be required to release the entrapped nerve in either location.12
