BackgroundTreatment of unstable intertrochanteric fracture in elderly patients remains challenging. The purpose of this prospective study is to determine clinical and radiological results of cementless bipolar hemiarthroplasty using a fully porous-coated stem in osteoporotic elderly patients with unstable intertrochanteric fractures with follow-up over 5 years.MethodsFrom January 2010 to December 2011, we performed 123 cementless bipolar hemiarthroplasties using fully porous-coated stem to treat unstable intertrochanteric fractures in elderly patients with osteoporosis. Clinical and radiographic evaluations were performed.ResultsFifty-three patients died and 14 patients were lost during the follow-up period. Mean follow-up period was 61.8 months postoperatively. Their mean Harris hip score was 77 points (range 36-100). None of these hips had loosening of the stem or osteolysis. Postoperative complications included nonunion of greater trochanter in 2 hips and dislocation in 2 hips. Two patients were reoperated due to periprosthetic fracture. One patient underwent implant revision due to periprosthetic infection. Thirty-one patients maintained walking activities similar to those before fracture. With follow-up period of 83 months, cumulative survival rates were 97.3% and 99.1% with reoperation for any reason and femoral stem revision as endpoint, respectively.ConclusionCementless bipolar hemiarthroplasty using a fully porous-coated stem is a useful surgical treatment option for unstable intertrochanteric fracture in elderly patients with osteoporosis.Copyright © 2017 Elsevier Inc.
