Abstract：
OBJECTIVE: Restoration of pinch and grasp is a chief concern of patients with cervical spinal cord injury or peripheral nerve injury involving the anterior interosseous nerve (AIN). We hypothesize that supinator nerve-to-AIN (Sup-AIN) nerve transfer is a viable option for AIN neurotization.
METHODS: We performed a retrospective review of patients who received Sup-AIN. Reported outcomes included Medical Research Council strength of the flexor digitorum profundus and flexor pollicis longus and passive range of digit motion. Patients with <12 months of follow-up were excluded.
RESULTS: Eleven patients underwent Sup-AIN, eight with peripheral nerve injury, and three with spinal cord injury. Three patients were excluded because of insufficient follow-up. Average follow-up was 17 months (range: 12-25 months). Six patients had M4 recovery (75%), one patient had M3 recovery (12.5%), and one did not recover function because of severe stiffness (12.5%). We observed no complications or donor site morbidity in our patients.
CONCLUSIONS: The Sup-AIN nerve transfer is an effective option to restore digital flexion in patients with peripheral nerve injury or spinal cord injury involving the AIN motor distribution. In comparison to previously described extensor carpi radialis brevis to AIN and brachialis to AIN nerve transfers, Sup-AIN offers the benefits of a more expendable donor nerve and shorter regenerative distance, respectively. The one failed Sup-AIN in our series highlights the importance of patient selection.
METHODS: Therapeutic V.

摘要：
目的：颈脊髓损伤或涉及骨间前神经（AIN）的周围神经损伤患者的主要问题是恢复夹紧和抓握。我们假设旋肌神经到AIN（Sup-AIN）神经转移是AIN神经化的可行选择。
方法：我们对接受Sup-AIN的患者进行了回顾性分析。报告的结果包括医学研究委员会的屈指和屈指的力量以及手指运动的被动范围。随访时间<12个月的患者被排除在外。
结果：11例患者接受了Sup-AIN，八人周围神经损伤，和三个脊髓损伤。3例患者因随访不足被排除。平均随访17个月（范围：12-25个月）。6例患者M4恢复（75%），一名患者M3恢复（12.5%），和一个没有恢复功能，因为严重的刚度（12.5％）。我们在我们的患者中没有观察到并发症或供体部位发病率。
结论：Sup-AIN神经转移是涉及AIN运动分布的周围神经损伤或脊髓损伤患者恢复手指屈曲的有效选择。与先前描述的桡骨短伸肌到AIN和肱肌到AIN神经转移相比，Sup-AIN提供更消耗性的供体神经和更短的再生距离的好处，分别。我们系列中失败的Sup-AIN突出了患者选择的重要性。
