Introduction: The aim of this study is to compare two methods of carpal tunnel release. One is the radial approach open carpal tunnel release, the other one is two-incision open carpal tunnel release. There is less loss of carpal ligament pulley, no volar cutaneous nerve injury in radial approach carpal tunnel release. Function recovery should be better.  We use DASH score and Levine score to evaluate the functional recovery after surgery.

Materials and Methods: There were 19 patients with pure carpal tunnel syndrome in one-year period. Patients with other hand diseases were excluded from our study. There were 9 patients in radial approach group, 10 patients in two-incision group. The age distribution was similar. Postoperative evaluation methods were DASH score and Levine score.

Results: For DASH score, preoperative score is similar between two groups. In postoperative 3 months, in radial approach CTR the score is smaller, which means better functional results but no statistical significance. 

For Levine symptom severity score and functional score, preoperative score is similar between two groups. In postoperative 3 months, in radial approach CTR the score is smaller, which means better functional results but no statistical significance.

Conclusions: Radial approach open carpal release seemed to be better than two-incision open carpal tunnel release according to the DASH and Levine scores evaluation. However, the results were not statistically significant. The patient number was small, which might have effect on the results. In the future, we should increase the patient number for more comprehensive study.
