We report the complications of prophylactic pinning of slipped upper femoral epiphysis with Crawford Adams pins in 95 cases. Complications of pin placement were seen in 13.7%. Although seven hips had penetration of the joint, there were no cases of chondrolysis or avascular necrosis. Excavation of the lateral femoral cortex was required at pin removal in 12.5% of cases. Analysis of the growth around pins allowed recommendations to be made regarding pin protrusion. The use of improved fixation devices may reduce the need for multiple pins.
我们报告了使用克劳福德·亚当斯针预防性固定95例股骨头骨骺滑脱的并发症情况。针置入相关并发症发生率为13.7%。虽然有7例髋关节出现针穿透关节的情况，但未发生软骨溶解或缺血性坏死病例。12.5%的病例在取出针时需要对股骨外侧皮质进行清理。通过分析针周围的生长情况，就针的突出问题提出了建议。使用改进的固定装置可能会减少多根针的使用需求。
