SRM standardized response mean, ES effect size, VAS pain visual analogue scale for wrist pain, % GS a proportional grip strength of the affected wrist compared to the contralateral side, % FEM a proportion of range of active flexion–extension movement of the affected wrist compared with the contralateral hand, % RUM a proportional active radial and ulnar deviation motion of the affected wrist compared to the contralateral side, % SPM a proportional active supination and pronation motion of the affected extremity compared to the contralateral side
* Significant difference between preoperative and postoperative median value (P < 0.05)
*** Significant difference between preoperative and postoperative median value (P < 0.001)
