Abstract

Modular femoral stem-head systems are used increasingly due to their ease of application and offset adjustment. However, this modular ity has brought complications of trunnion wear and breakage. Although very rarely encountered, trunnion fracture is a catastrophic com plication that requires challenging revision surgery. This report presents a trunnion fracture of a cobalt-chrome alloy, fully porous-coated femoral stem. Following single-stage revision surgery, full weight-bearing was achieved in six weeks, and the patient was painlessly mobile with a single cane and had a Hip Score of 81 in the last follow-up. Despite all the advantages of the femoral stem and head modu larity, one should remember that a catastrophic complication such as trunnion wear and fracture that require revision surgery is possible.

钴铬全多孔涂层股骨干耳轴骨折1例。
模块化股骨头系统由于其易于应用和偏移调整而越来越多地使用。然而,这种模块化带来了耳轴磨损和断裂的并发症。虽然很少遇到,但耳突骨折是一种灾难性的并发症,需要具有挑战性的翻修手术。本文报道一例钴铬合金全多孔包覆股骨干耳轴骨折。在单期翻修手术后,患者在6周内实现了完全负重,患者可以用单手杖无痛地活动,最后一次随访时髋关节评分为81。尽管股骨头和股骨头模组有所有的优点,但我们应该记住,灾难性的并发症,如耳轴磨损和骨折,需要翻修手术是可能的。
