A customized dynamic hip screw for valgus osteotomy in femoral neck nonunion with remarkable anatomy: A case report

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. Ther...

description 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.
