Abstract
A retrospective study was performed on 62 patients who had undergone carpal tunnel decompression surgery. Each patient was assessed in clinic, their case notes were reviewed and their electrophysiological results were analysed and graded according to severity. The median preoperative duration of symptoms was 2 years. No relationship was found between the nature or duration of pre-operative symptoms and the severity of the electrophysiological impairment. Furthermore, no relationship could be identified between pre-operative nerve conduction impairment and either successful outcome of surgery (defined as complete symptom relief) or time to resolution of symptoms after surgery.
