A neuroma of the palmar cutaneous branch (PCB) of the median nerve can cause pain in the scar following carpal tunnel release, with secondary decreased wrist range of motion and decreased grip strength. The results of PCB resection and implantation of the PCB into the pronator quadratus muscle are reported in a series of 13 patients. Pain relief was demonstrated before surgery by anesthetic block of the PCB, which did not result in sensory loss in the distribution of the median nerve. Results, at a mean of 19 months after surgery, were excellent (no residual pain, return to previous jobs) in six patients and good (some residual pain, return to a different job, stable or improved grip strength and wrist range of motion) in seven patients.
正中神经掌皮支（PCB）神经瘤可导致腕管松解术后瘢痕处疼痛，继而导致腕关节活动范围减小和握力下降。本文报告了13例PCB切除并将其植入旋前方肌的病例结果。术前通过PCB麻醉阻滞证实疼痛缓解，且未导致正中神经分布区感觉丧失。术后平均19个月时，6例患者效果极佳（无残留疼痛，恢复原工作），7例患者效果良好（有一些残留疼痛，更换工作，握力和腕关节活动范围稳定或改善）。
