Abstract:
Objective To explore clinical effects of local anesthesia non-tourniquet technique in surgery for the treatment of cubital tunnel syndrome.Methods Between July 2020 and June 2023,20 patients with severe cubital tunnel syndrome were treated by using local anesthesia non-tourniquet technique.The local anesthetic was prepared,consisting of lidocaine with epinephrine,and in situ ulnar release was performed.Based on the evaluation for ulnar nerve instability,a decision was made on whether to perform anterior transposition of the ulnar nerve or not.Results In situ ulnar release was performed in 13 cases and anterior subcutaneous transposition of the ulnar nerve due to ulnar nerve subluxation were conducted in 7 cases.During anesthesia injection,there was only mild pain in the first injection[Numerical Rating Scale(NRS)score of 2-3 points],mild pain during intraoperative procedures(NRS score of 1-2 points),and mild to moderate pain after surgery(NRS score of 1-6 points).No anesthetic complications were recorded and the wound healed well.All the cases were followed up for 8-22 months(mean,17.1 months).According to classification of cubital tunnel syndrome introduced by Gu Yudong,the results were excellent in 5 patients,good in 12 patients and fair in 3 patients,with an excellent and good rate of 85.0％(17/20).At the last follow up visit,the 2-point discrimination of the little finger was 4-7 mm(mean,5.1 mm).Conclusion The local anesthesia non-tourniquet technique is safe and effective in surgery for the treatment of severe cubital tunnel syndrome,being worthy of clinical application.
