Objective : To compare the operative outcome of carpal tunnel release between limited open carpal tunnel release using direct
vision and tunneling technique (group A) with standard open carpal tunnel release (group B).
Material and Method: Twenty-eight patients were enrolled in the present study. A single blind randomized control trial study
was conducted to compare the postoperative results between group A and B. The study parameters were Levine’s symptom
severity and functional score, grip and pinch strength, and average two-point discrimination.
Results : The postoperative results between two groups were comparable with no statistical significance. Only grip strength
at three months follow up was significantly greater in group A than in group B.
Conclusion : The limited open carpal tunnel release in the present study is effective comparable to the standard open carpal
tunnel release. The others advantage of this technique are better cosmesis and improvement in grip strength at the three
months postoperative period.
