PURPOSE: We designed a reusable median nerve protector for endoscopic carpal tunnel release (ECTR) and prospectively evaluated its safety and efficacy.
TYPE OF STUDY: Therapeutic study--Investigating the results of treatment.
METHODS: Seventy-two patients (97 palms) with carpal tunnel syndrome were operated on endoscopically with the new median nerve protector. Patients were followed-up at 1, 3, 6, 12, and 24 weeks postoperatively. Evaluation included the symptom severity scale, functional status scale, wound pain and scar tenderness, monofilament sensory mapping, grip strength measurement, and pin strength gauge.
RESULTS: No patients sustained iatrogenic neurovascular injury or hematoma, but 3 developed superficial wound infections postoperatively. The symptom severity score decreased from 3.8 points preoperatively to 2.3 at 1 week, 1.9 at 3 weeks, and 1.3 at 6 weeks, and remained at 1 point at 12 and 24 weeks postoperatively. The functional status score dropped from 3.8 points to 2.8 at 1 week, 2 at 3 weeks, 1.5 at 6 weeks, and 1 at 12 weeks and thereafter. Semmes Weinstein monofilament mapping improved in all operated hands (59) of the 44 patients not lost to follow-up by 24 weeks. Tip pinch testing and grip strength showed gradual improvement as early as 3 weeks postoperatively. The mean value of the postoperative scar tenderness score dropped from 2.4 points at 1 week to 1.7 points at 3 weeks, 1.3 at 6 weeks, 1.2 at 12 weeks, and 1 point after 12 weeks.
CONCLUSIONS: This new median nerve protector provides clear visualization of neurovascular structures and is a safe and reliable tool for single-portal ECTR.
LEVEL OF EVIDENCE: Level IV.
