Supracondylar fractures in patients with total knee prostheses are challenging surgical problems for which there has been no single satisfactory method of management. The authors present four cases to show that a fully cannulated, closed-section, stainless steel supracondylar intramedullary nail can be inserted in a closed fashion through a 3 cm longitudinal patellar splitting incision between the metal condyles of a nonconstrained femoral component of a total knee prosthesis. The nail can be interlocked with percutaneous screws and provides primary stability of a supracondylar femoral fracture, even in the presence of total knee and total hip prostheses.
全膝关节置换患者的髁上骨折是具有挑战性的外科问题，目前尚无单一令人满意的处理方法。作者报告4例病例，表明可通过在全膝关节置换非限制性股骨组件的金属髁间作3cm纵行髌旁切口，以闭合方式插入全空心、封闭截面的不锈钢髁上髓内钉。该髓内钉可通过经皮螺钉锁定，即使在存在全膝关节和全髋关节假体的情况下，也能为股骨髁上骨折提供初始稳定性。
