From 1991 to 1994, 375 supracondylar fractures had percutaneous pinning after closed or open reduction. Nineteen of these with normal preoprative neurologic examinations had postoperative ulnar nerve palsies. All but two of the 19 were followed up. These 17 patients had complete return of function. Only four of the 17 had the medial pins removed, and two others had explorations, which showed no interruption of the nerve. Many of these patients did not have complete return of function until after 4 months. From this and other studies, it is clear that ulnar nerve palsies occurring after percutaneous pinning of the supracondylar fracture usually resolve spontaneously.
1991年至1994年期间，375例髁上骨折在闭合或切开复位后接受了经皮穿针固定。其中19例术前神经检查正常的患者术后出现尺神经麻痹。19例中除2例之外均进行了随访。这17例患者的功能完全恢复。17例中只有4例取出了内侧钢针，另外2例进行了探查，结果显示神经未中断。这些患者中有许多直到4个月后功能才完全恢复。从这项研究和其他研究来看，很明显髁上骨折经皮穿针固定后发生的尺神经麻痹通常会自发缓解。
