I. Atroshi et al., ENDOSCOPIC CARPAL-TUNNEL RELEASE - PROSPECTIVE ASSESSMENT OF 255 CONSECUTIVE CASES, Journal of hand surgery. British volume, 22B(1), 1997, pp. 42-47
A prospective study was conducted to evaluate the efficacy and safety
of two-portal endoscopic carpal tunnel release, Two hundred and fifty-
five consecutive hands (204 patients) were operated on by one surgeon
using general or regional anaesthesia in the first 48 hands and local
anaesthesia in the following 207 hands. The patients were evaluated pr
eoperatively and 3 and 6 months postoperatively by an independent exam
iner. At the 6-month follow-up, 83% reported complete relief of sympto
ms and 89% were satisfied with the results of surgery. The median time
until return to work was 17 days. Complications included five postope
rative digital neurapraxias, all occurring under general or regional a
naesthesia, and four open reoperations due to persistent symptoms. Two
-portal endoscopic carpal tunnel release can be effective and safe and
appears to shorten the time until return to work. The use of local an
aesthesia might be important in avoiding neurological complications.
