Abstract: Objective To explore the effects of minimally invasive percutaneous plate osteosynthesis （MIPPO）combined with Non?Contact?Bridging（NCB）universal in the treatment of femoral intertrochan-teric fractures in the elderly. Methods A total of 35 patients with femoral intertrochanteric fractures were included in this paper from Jul. 2013 to Oct. 2015. Of them, there were 21 males and 14 females；16 right hips, 19 left hips；aged 68 to 92 years with a mean age of 83.5 years, Evans type Ⅰ type in 2 cases, type Ⅱ in 5 cases, typeⅢ in 11 cases, typeⅣ in 10 and type Ⅴ in 7. All patients underwent X-ray pelvic radiographs and CT scans before operation. The operative time, intraoperative blood loss, complications, fracture healing time, Harris hip score at the final follow-up were recorded, and the results were analyzed. Results The average operation time was 50.2 minutes（40~65）, and the average intraoperative blood loss was 180 ml（150~230）. All the 35 patients were followed up for an average of 15.6 months（12 to 39 months）after surgery. One patient developed postoperative internal fixation and then hemiarthroplasty. Another 34 patients received bony union after operation. The average healing time was 7.8 months（6 to 9）. At the final follow-up, 34 patients had an average Harris hip score of 84.5 points（75 to 90 points）. Conclusion Surgical procedure of MIPPO combined with NCB is an effective and reliable treatment for intertrochanteric fractures in the elderly, especially for osteoporotic intertro?chanteric fractures, which can achieve better reset and early stability.
