Abstract：
The purpose of this study was to compare two sources of nerve graft for brachial plexus reconstruction: the denervated superficial branch of the radial nerve (SBRN) and the sural nerve. Ninety-seven patients who underwent brachial plexus reconstruction with denervated SBRN nerve (24 patients with 24 grafts) or with sural nerve grafting (73 patients with 83 nerve grafts) were included. The two groups were compared with respect to postoperative muscle reinnervation, disabilities of the arm, shoulder, and hand (DASH) scores. In the SBRN group, only four (17%) of the nerve grafts provided grade III or higher muscle function. In the sural nerve group, 31 (37%) of the nerve grafts provided grade III or higher muscle function. Smoking had a negative impact on muscle recovery. Denervated SBRN grafts are associated with inferior outcomes when compared with sural nerve grafts in the treatment of traumatic adult brachial plexus injuries.

摘要：
本研究的目的是比较臂丛神经重建的两种神经移植物来源：radial神经的失神经浅支（SBRN）和腓肠神经。包括97例接受神经支配的SBRN神经重建（24例，24例）或腓肠神经移植（73例，83例神经移植）的患者。比较两组患者术后肌肉神经支配情况,手臂的残疾，肩膀,和手（DASH）得分。在SBRN组中，只有四个（17％）的神经移植物提供了III级或更高的肌肉功能。在腓肠神经组中，31（37％）的神经移植物提供了III级或更高的肌肉功能。吸烟对肌肉恢复有负面影响。在外伤性成人臂丛神经损伤的治疗中，与腓肠神经移植物相比，去神经支配的SBRN移植物的预后较差。（外科骨科杂志进展33（2）：080-083，2024）。
