Comparison of clinical effects of total artificial hip replacement and cannulated screw fixation for the treatment of displaced femoral neck fractures in elderly patients / 中国骨伤

ABSTRACT

<p><b>OBJECTIVE</b>To compare of clinical effects of different surgical methods in the treatment of elderly femoral neck fractures.</p><p><b>METHODS</b>From January 2013 to June 2016, 144 elderly patients with femoral neck were treated and divided into artificial hip replacement group and cannulated screw fixation group according to the surgical methods. In the total hip arthroplasty group, there were 89 cases, 28 males and 61 females, with an average age of(84.10±3.10) years old;Hollow nail fixation group 55 cases, 20 males and 35 females, with an average age of (86.80±2.88) years. Preoperative patients data, postoperative complications, mortality and postoperative Harris hip score were compared between the two groups.</p><p><b>RESULTS</b>A total of 144 cases were followed up for 12 to 36 months with an average of 18 months. There was no significant difference between two groups in gender, fracture side, preoperative complications, osteoporosis, ASA score, injury to surgery interval, the number of patients admitted to ICU and perioperative death. However, the patients in hollow screw fixation group was older than the joint replacement group(=5.311,<0.05);The degree of preoperative fracture displacement in the joint replacement group was higher than that in the hollow nail fixation group(χ²=6.894,=0.009<0.05);Hollow nail fixation group in operation time, hospital stay, intraoperative blood loss, perioperative blood transfusion was significantly better than the number of joint replacement group(<0.05);The Harris score of the joint replacement group was higher than that of the hollow screw fixation group(<0.05).</p><p><b>CONCLUSIONS</b>For elderly femoral neck patients, if there is a significant shift in the fracture (Garden III, IV), the preferred treatment is hip replacement. Postoperative complications are relatively small, satisfactory joint function recovery. If the fracture displacement is not obvious (Garden type I, II) or patients with more medical diseases, poor physical condition, poor surgical tolerance, postoperative life expectancy is not high, the first choice is closed reduction and cannulated screw fixation.</p>
