Cubital Tunnel Syndrome: Current Concepts.

Cubital tunnel syndrome is the second most common upper extremity compressive neuropathy. In recent years, rates of surgical treatment have increased, and the popularity of in situ decompression has grown. Nonsurgical treatment, aiming to decrease both compression and traction on the ulnar nerve about the elbow, is successful in most patients with mild nerve dysfunction. Recent randomized controlled trials assessing rates of symptom resolution and ultimate success have failed to identify a preferred surgical procedure. Revision cubital tunnel surgery, most often consisting of submuscular transposition, may improve symptoms. However, ulnar nerve recovery after revision cubital tunnel surgery is less consistent than that after primary cubital tunnel surgery.
