We report the treatment of femoral neck nonunion in an adult female who has remarkable femoral neck anatomy. The initial fracture was treated by closed reduction and multiple screws incorporated pin fixation. Eventually, nonunion with implant loosening developed after about 10 following months. Therefore, trochanteric valgus osteotomy and dynamic hip screw fixation was determined to treat the nonunion. As a result of implant-anatomy mismatching, the customized lag screw was designed to compromise both of the particular anatomy and the ordinary side plate. The implant was manufactured using a Computer Numerical Control (CNC) machine. Finally, the nonunion and osteotomy site completely healed without complication.
我们报告了一名成年女性股骨颈骨不连的治疗情况，该女性具有显著的股骨颈解剖结构。最初的骨折采用闭合复位和多枚螺钉结合针固定治疗。最终，在大约10个月后出现了伴有植入物松动的骨不连。因此，决定采用粗隆间外翻截骨术和动力髋螺钉固定来治疗骨不连。由于植入物与解剖结构不匹配，设计了定制拉力螺钉以兼顾特殊的解剖结构和普通侧板。植入物使用计算机数控（CNC）机床制造。最后，骨不连和截骨部位完全愈合，无并发症发生。
