Abstract:
Objective:To investigate the clinical effect of Infix combined with hollow screws for the treatment of pelvic injuries with pubic symphysis separation in middle-aged and elderly patients.Methods:Data of 8 middle-aged and elderly patients with pelvic injuries due to pubic symphysis separation undergone treatment from January 2017 to December 2020 were retrospectively analyzed.Results:The average operating time of 8 patients was (46.0±6.2)min(range: 40-62min); the average intraoperative blood loss was (32.0±5.6)ml(range: 25-50 ml); the average length of incisions at the iliac screw was(2.6±0.4)cm(range: 2.0-3.5 cm); the average length of incisions at the hollow screw was (1.1±0.3)cm(range: 0.8-1.5 cm); and the average times of fluoroscopy were (36.0±6.0)times(range: 28-52 times). Postoperative X-ray and CT examinations showed that the reduction of the pubic symphysis was good, the inserted iliac screws and cannulated screws were positioned accurately, and the incision healed well.Based on Matta's criteria, postoperative radiological outcomes were evaluated, with 7 cases rated as excellent and 1 as good, giving an excellent to good rate of 100%(8/8). The average followed up time for all 8 patients was (15.0±4.2)months(range: 6-24 months). Pelvic X-ray and CT examinations at the last follow-up showed that the fractures healed well and the pubic symphysis reduction did not fail.Infix and cannulated screws in the pubic symphysis were removed 10-12 weeks after surgery[average: (10.5±0.5)weeks]. According to the Majeed Pelvic Score, 5 cases were rated as excellent, 2 cases as good and 1 as fair, with an excellent to good rate of 87.5%(7/8). One patient had symptoms related to the lateral femoral cutaneous nerve that disappeared after 3 months.One patient developed deep venous thrombosis after surgery, and the filter was placed and removed 10 weeks later.Conclusions:Using Infix plus cannulated screws for the treatment of pelvic injuries in middle-aged and elderly patients with pubic symphysis separation has the advantages of limited trauma and intraoperative blood loss, good fixation and few complications.
