Abstract
A postal survey within the North West Region (UK) revealed that 66% of the consultant orthopaedic surgeons did not use local anaesthesia routinely for carpal tunnel decompression. This prospective study was set up to assess the effectiveness, safety and patient tolerance of performing this procedure using local anaesthesia and upper arm tourniquet control. Eighty-six carpal tunnel decompressions were performed on 75 consecutive and unselected patients with confirmed carpal tunnel syndrome over a 6-month period. Completed questionnaires were obtained before discharge. None or only slight discomfort was experienced for all aspects of the operation in at least 94%. None of the patients reported severe and unbearable discomfort. At review, 3 months postoperatively, all patients with the exception of two reported complete resolution of preoperative symptoms. The use of local anaesthesia and a tourniquet is safe, effective and well-tolerated in carpal tunnel decompressions.
