Purpose
The aim of this study was to report clinical results of anterior submuscular transposition of the ulnar nerve in patients with severe cubital tunnel syndrome. Methods: We retrospectively reviewed fifteen patients with grade Ⅲ cubital tunnel syndrome based on McGowan’s classification, which was associated with marked intrinsic muscle atrophy, claw-hand deformity and sensory loss. All patients were treated with anterior submuscular transposition of the ulnar nerve. The postoperative improvement of pain, sensory and motor at the final follow-up were assessed according to the Gabel and Amadio’s rating scale. Overall functional outcomes were evaluated by Akahori’s criteria. We analyzed the statistical correlation of patient's age and symptom duration with clinical results. Results: At an average follow-up of 36 months (12 to 100 months), pain and numbness improved in 9 out of 15 patients, but motor function improved only in 6 patients. According to Akahori’s criteria, only 27% demonstrated satisfactory results (excellent in 2 patients, good in 2 patients, fair in 6 and poor in 5 patients) after operation. Old age and prolonged duration of symptom affected the functional outcome negatively. Conclusion: Patients with severe cubital tunnel syndrome can expect some improvement of pain and sensory loss after surgery while motor weakness and clawhand deformity tend to be remained despite of operation particularly in old patients, who have long standing symptoms. We recommend early decompression of the ulnar nerve in patients with progressive cubital tunnel syndrome to achieve better clinical outcomes. |
