[Agee endoscopic operation of carpal tunnel syndrome in comparison with open surgical technique]

In the course of a prospective randomised study, 120 patients underwent a carpal tunnel release procedure. The follow-up documentation included 101 patients. 54 patients had the conventional open procedure, including epineural neurolysis of the median nerve. 47 patients were treated with the Agee endoscopic procedure. The documentation included: patients age, sex, profession, duration of treatments, disablement, return to the activities of daily life (ADL) and pre- and postoperative neurological symptoms and postoperative complications. The electroneurographical measurements were performed preoperatively and nine months after operation by the same neurologist. The open and endoscopic carpal tunnel release procedures are described and the study results are reported. None of the 101 patients had wound-healing impairments. Clinical and neurological follow-up examinations did not reveal any signs of injured nerves or tendons. The study shows that the endoscopic group returned to work significantly earlier compared to the control group. At the same time, the Agee group had reduced postoperative pain symptoms. Regarding the long-term results, no significant difference between both groups was found. Based on the electrophysiological results, the study shows that epineural neurolysis of the median nerve is not necessary.
