Through a retrospective evaluation of 1,683 consecutive total hip arthroplasties performed exclusively by the senior author, a progressive occurrence of distal cortical hypertrophy of the bone on the medial and/or lateral portion of the femur was noted in 58 hips. All patients with evidence of hypertrophy had age, sex, weight, prosthetic design and alignment, radiolucency, and calcar resorption noted. A control was established by randomly selecting an equal number of patients without distal cortical hypertrophy for direct statistical comparison. It was concluded that hypertrophy following total hip arthroplasty is a result of abnormal stress distribution in the loaded femur and is not an indication of pain or loosening. Women with the stainless steel T-28 prosthesis were the most prone to hypertrophy.
通过对由资深作者单独实施的1683例连续全髋关节置换术进行回顾性评估，发现58例髋关节出现股骨内侧和/或外侧骨皮质远端进行性肥厚。所有有肥厚证据的患者均记录了年龄、性别、体重、假体设计与对线、透亮线及股骨距吸收情况。通过随机选择同等数量无远端皮质肥厚的患者作为对照进行直接统计学比较。得出结论，全髋关节置换术后的肥厚是负重股骨应力分布异常的结果，并非疼痛或松动的指征。使用不锈钢T-28假体的女性最易发生肥厚。
