Clinical observation of improved proximal femoral locking plate in treating osteoporotic intertrochanteric fractures / 中国骨伤

ABSTRACT

<p><b>OBJECTIVE</b>To investigate the effects of proximal femoral locking plate (PFP) in treating osteoporotic intertrochanteric fractures and to analyze the failure cases.</p><p><b>METHODS</b>Totally 32 patients with osteoporotic intertrochanteric fractures of Evans I and II were treated with improved locking PFP, including 17 males and 15 females with an average age of 77.3 years old ranging from 70 to 86 years old. After operation, according to Harris hip scores, the hip function and therapeutic effects were evaluated.</p><p><b>RESULTS</b>The observed 32 patients' operative time was (60.5±15.7) min, intraoperative blood loss was (128.8±73.6) ml;perioperative blood transfusion was (224.0±72.7) ml. Hospitalization time was from 14 to 20 d with an average of 17.2 d. All patients were followed up from 6 to 18 months with an average of 14.1 months. The fracture healing time was from 3 to 6 months with an average of 3.1 months. One patient occurred internal fixation loosening and screw backward, 4 cases occurred urinary tract infection, 1 patient died of cardiovascular disease for 6 months postoperative, 2 patients died of a stroke for 1 year postoperative. No incision deep infection, peri internal fixation fractures, lower extremity deep venous thrombosis, internal fixation breakage, nonunion, severe coax vara and coax valgus occurred. The final Harris score was 89.74±6.84, the result was excellent in 10 cases, good in 16 cases, fair in 4 cases, and poor in 2 cases.</p><p><b>CONCLUSIONS</b>Locking PFP can provide relative stable fixation to proximal end of osteoporotic femoral fractures, which is a good choice for the treatment of intertrochanteric fractures. It could provide stableness of fractures and bone union, even avoid screws loose or slide out.</p>
