Abstract:
Objective:To evaluate the efficacy of ulnar nerve decompression (cubital and ulnar tunnels) in double crush syndrome (DCS) of the ulnar nerves.Methods:A retrospective analysis was performed on the clinical data of 23 patients with DCS of the ulnar nerves in Peripheral Specialty of Neurosurgery Department, Japan-China Friendship Hospital from June 2018 to December 2022. All patients underwent both cubital tunnel decompression and ulnar tunnel decompression. Efficacy was evaluated by observing improvement of subjective symptoms and objective indicators and ulnar nerve motor function.Results:Follow-up was performed for (25.82±9.3) months, ranged 9-42 months, in these 23 patients. At the final follow-up, 20 patients (86.95%) had numbness relief, all 23 patients (100%) reported pain alleviation, 12 patients (52.17%) had improved muscle atrophy, and 18 patients (78.26%) had improved motor dysfunction;the sensory nerve conduction velocity ([42.13±2.8] m/s) after decompression was significantly increased than that before decompression ([31.74±3.9] m/s), and the motor nerve conduction velocity ([41.57±2.9] m/s) after decompression was significantly increased than that before decompression ([28.39±6.1] m/s, P<0.05); two-point discrimination threshold of the ring finger ([7.43±1.3] mm) after decompression was significantly decreased than that before decompression ([8.48±1.9] mm, P<0.05); and excellent functional recovery rate of the ulnar nerves was 82.6% (19/23). During the follow-up, no recurrence appeared. Conclusion:Clear efficacy of ulnar nerve decompression (cubital and ulnar tunnels) in DCS of the ulnar nerves is noted.
