Varus alignment of the femoral component is associated with femoral component loosening in total hip arthroplasty performed for Paget's disease. Irregular and hemorrhagic bone, along with angular femoral deformity, was encountered during revision total hip arthroplasty in three pagetic patients. A diaphyseal femoral osteotomy facilitated cement removal and provided an opportunity for correction of the deformity. The step-cut configuration of the osteotomy provided intrinsic rotational stability of the femoral segments around a modular, long-stem cementless implant. Excellent clinical and radiographic results were achieved, but moderate blood loss and delayed healing of the osteotomy site were observed.
在为佩吉特病施行的全髋关节置换术中，股骨组件的内翻对线与股骨组件松动相关。在3例佩吉特病患者的翻修全髋关节置换术中，遇到了不规则且出血的骨质以及股骨角状畸形。股骨干截骨术有助于取出骨水泥，并为矫正畸形提供了机会。截骨术的阶梯状构型为围绕模块化、长柄非骨水泥型植入物的股骨段提供了内在的旋转稳定性。取得了优异的临床和影像学结果，但观察到有中度失血和截骨部位愈合延迟的情况。
