Background: Cubital tunnel syndrome is the second most common entrapment neuropathy in the upper limb; however, surgical treatment of the ulnar nerve entrapment at the elbow remains controversial. Objective: To assess patient outcomes and complication rates after simple decompression of the ulnar nerve in cubital tunnel syndrome. Subjects and Methods: A retrospective clinical review of 30 patients who underwent simple decompression of the ulnar nerve for cubital tunnel syndrome in a 5-year period. Patients were diagnosed by a history, clinical examination and a positive electrodiagnostic test. Results: Out of the 30 patients, 21 patients are males and 9 patients are females. The mean age of the patients in this study is 39.5 years (range from 27 to 52 years) .Favorable clinical outcomes were obtained on 26 patients (86.5%). Superficial wound infection has observed in 2 patients (6.5%). Conclusion: Simple decompression of the ulnar nerve is effective and reliable treatment for cubital tunnel syndrome. The results and complications in this series were comparable with other publications.
