[Reoperation in carpal tunnel syndrome. Retrospective analysis].

BACKGROUND

The goal of this study was the reexamination, description, and analysis of postoperative results after carpal tunnel release reoperation.

PATIENTS AND

METHODS

Thirty-eight patients were examined retrospectively 2 years after reoperation of carpal tunnel release. All of them had had complaints after the first operation. On the basis of DASH and Amadio questionnaires after the reoperation, the patients were divided into two groups: good results and inadequate results.

RESULTS

The reasons for reoperation included incomplete division of the retinaculum, early fibrosis, reoccurrence, late fibrosis, intraoperative complication, and one unclear situation. A quarter of the patients were free of complaints; three quarters had symptoms in which sensation improved but strength and function did not.

CONCLUSION

The clinical findings showed satisfying results for the patients. Reoperation is indicated after early postoperative deterioriation or if there is no improvement.
