We present an elderly lady with an intertrochanteric fracture of a previously fused hip. A 3D printed model of her pelvis and femur was used for implant templating before surgery. Minimal invasive fixation was performed with a spanning reversed distal femur locking plate without the need for removal of the previous implant. Multiple long locking screws were placed in the supra-acetabular region. The patient had union in 4 months, return to function and no complication.
The technique allowed us to optimize implant selection and insert screws safely at difficult trajectories using minimal invasive surgery.
我们介绍一位老年女性,其既往融合的髋关节发生转子间骨折。术前使用她的骨盆和股骨的3D打印模型进行植入物模板制作。采用跨越股骨远端反向锁定钢板进行微创固定,无需取出先前的植入物。在髋臼上区域置入多根长锁定螺钉。患者在4个月时实现骨愈合,恢复功能且无并发症。
该技术使我们能够优化植入物选择,并通过微创手术在困难的轨迹上安全地置入螺钉。
