文摘

Carpal tunnel syndrome is treated successfully by surgical release of the transverse carpal ligament (TCL). However, persistent weakness of grip and pain over the thenar and hypothenar ends of this ligament, and “pillar pain”, are reported to be common complications. In order to reduce these complications, different ligament reconstruction or lengthening techniques have been proposed.

Objective

The purpose of this study is compare effectiveness and complications of TCL z-lengthening technique with complete TCL section.

Methods

A prospective, randomised, intervention trial was conducted on 80 patients. The patients were divided into 2 groups: (1) complete release of TCL; (2) z-lengthening of TCL according to a modified Simonetta technique.

Grip strength, pillar pain and clinical and functional assessment were carried out using the Levine et al. questionnaire.

Results

No significant differences were observed (P > .05) in the postoperative reviews between the two groups as regards grip strength loss and pillar pain. There were significant differences between preoperative and postoperative mean Levine scores, but there was no difference in the mean scores of the two procedures at any time.

Discussion

In conclusion, according to the results, TCL z-lengthening is more effective than simple division, but there is no identifiable benefit in z-lengthening for avoiding complications.
