OBJECTIVES: To evaluate the clinical results of femoral proximal fracture with complex hip diseases using an uncemented extensively porous-coated long femoral stems.
METHODS: 15 cases of femoral proximal fracture with complex hip diseases treated with the uncemented extensively porous-coated long femoral stem were retrospectively reviewed. All patients were followed up at 1, 3, 6, 12 months in the first year postoperatively and once a year from the second year on.Radiological evaluations were conducted using the related criteria, including anteropostierior radiograph of pelvis, anteropostierior and lateral radiograph of proximal femur, and flat tomography of lower limbs.The bone union of the femur fracture, the fixation of prosthesis, and periprosthetic bone loss were evaluated by above-mentioned radiography.The subsidence of femoral prosthesis was compared between 1 month postoperatively and the last follow-up. Complications during the follow-up period was recorded.Clinical outcomes were assessed with Harris Hip Score the last follow-up, including excellent (90-100), good (80-89), moderate (70-79) and bad (<70).
RESULTS: The average follow-up period was (45.5±21.7) months. All fractures were united at mean 12.6 weeks. There were no femoral stem subsidence and evidence of loosening both radiologically and clinically. The reconstructive offset for femoral fracture was 35.8 mm, while the contralateral offset was 34.8 mm. The average Harris Hip Score was 89.5 at the last follow-up. Moreover, no loosening, dislocation or infection were observed.
CONCLUSIONS: Total hip arthroplasty with extensively porous-coated long femoral stem provides a good fracture stability that promotes fracture healing and offers a successful solution for femoral proximal fracture with complex hip diseases.
