Ulnar Nerve Decompression: A Case Report

Abstract

Cubital tunnel syndrome is a condition characterized by ulnar nerve dysfunction at the elbow due to a combination of compression, traction and friction. It is the second most common condition of the ulnar nerve, behind carpal syndrome. The incidence rate is 21 cases per 100,000 people per year. Although electromyographic abnormalities are present in 33% of carpal syndrome cases, individuals with cubital tunnel syndrome are four times more likely to experience severe symptoms, such as muscle atrophy and reduced sensation. If left untreated, the syndrome can lead to irreversible loss of sensation, muscle weakness, and posterior joint contractures.

A 54-year-old male with clinical manifestations presented for ulnar decompression. The procedure included medial and posterior ulnar nerve dissection, techno-epitrochlear olecranial dissection, ulnar nerve dissection, complete ulnar nerve dissection, and deformity in the arena region.

Research has shown that simple decompression can have comparable results to more extensive surgeries. In a prospective, nonrandomized study, 51% of men and 70% of women who received surgical treatment for ulnar tibial syndrome were referred for a simple procedure. However, the cause of continued pain after a basic procedure remains unclear. Transposition has been used to treat inseparable ulnar nerves in some series, but its efficacy in other cases remains uncertain.
