ObjectiveTo compare the clinical efficacy of three minimally invasive methods of anterior column screw, plate and screw rod system in the treatment of anterior pelvic ring fracture.MethodsFrom December 2015 to September 2018, 77 patients with pelvic anterior ring fracture were treated and followed up, including 45 males and 32 females, aged 19 to 73 years. According to AO / OTA classification, there were 26 cases of type B1, 20 cases of type B2, 17 cases of type B3 and 14 cases of type C. According to the different internal fixation methods, they were divided into three groups:anterior column screw group(35 cases), plate group(20 cases), and screw rod system group(22 cases). The operation time, intraoperative fluoroscopy times, blood loss, fracture reduction quality, complications and curative effect of the three groups were compared.ResultsAll 77 patients were followed up for 12 to 33 (16.5±5.7) months. The operation time, intraoperative blood loss and incision length of anterior column screw group were significantly shorter than those of plate group and screw rod system group, and intraoperative fluoroscopy times of plate group were significantly less than those of anterior column screw group and screw rod system group (P<0.05). There was no significant difference in the quality of fracture reduction and curative effect among the three groups(P>0.05). The incidence of complications was significant different among three group(P<0.05).ConclusionMinimally invasive internal fixation with anterior column screw, plate and screw rod system can obtain good clinical effect, but anterior column screw fixation has less trauma and lower incidence of surgicalcomplications.
