Abstract

A broken lag screw of the cephalomedullary nail is a rare condition. Removal of the retained lag screw from the femoral head is also very challenging. This article describes a surgical technique and the modified instrument that was available in the operating room for removing the broken implant by closed technique.

Figure

• 

  Fig. 1 Radiograph showed nonunion of subtrochanteric fracture of right femur and breakage of a lag screw of long cephalomedullary.

• 

  Fig. 2 Postoperative radiograph showed union of subtrochanteric fracture of right femur without complication.

• 

  Fig. 3 The customized removal tool was created by modifying a 12 × 400 mm Arbeitsgemeinschaft für Osteosynthesefragen femoral interlocking nail.
