Since the advent of modular hip prostheses in the early 1970s, dissociation of the femoral trial head and migration into the deep tissue space of the pelvis are rarely reported complications of total hip arthroplasty. Several case reports have described this complication, but the actual incidence is unknown and likely underreported. Two cases are presented here using a new technique to retrieve a trial femoral head from within the pelvis without use of an extensile approach, laparoscopic retrieval, or secondary incisions.
自 20 世纪 70 年代初模块化髋关节假体问世以来，股骨干试模头的分离和向骨盆深部组织空间迁移是全髋关节置换术罕见的并发症。有几例病例报告描述了这种并发症，但实际发生率尚不清楚，而且可能报告不足。本文介绍了两种采用新技术从骨盆内取出试模股骨干头而不使用广泛入路、腹腔镜取出或二次切口的病例。
