Abstract: Objective  To observe the effect of CT three-dimensional reconstruction technique in the treatment of unstable pelvic fractures with anterior sacroiliac joint plate. Methods  From January 2020 to January 2022, Eighty patients with unstable pelvic fracture(treated in our hospital) were selected and divided into control group(40 cases) and combined group(40 cases) according to the random number table method.The control group was given anterior sacroiliac joint plate treatment,combined with CT three-dimensional reconstruction technology on the basis of the control group.Intraoperative and postoperative related indicators,pain degree,fracture reduction,fracture functional recovery and complications were compared.Results  There was no obvious difference in the amount of bleeding,fracture healing time,and preoperative VAS score between the two groups(P>0.05).Compared between the control group with the combined group,the time of getting out of bed [(4.52±0.57)w vs(5.14±0.63)w],weight bearing time [(9.75±1.12)w vs(11.53±1.26)w],hospital stay [(10.35±1.26)d vs(12.78±1.31)d] and operation time [(65.78±6.62)min vs(85.49±8.67)min],1 week [(4.72±0.64) vs(5.11±0.78)],2 weeks [(4.01±0.57) vs(4.65±0.64)],4 weeks [(2.31±0.27) vs(3.45±0.36)]VAS scores were lower than those of the control group(P<0.05).The excellent and good rate of fracture reduction(97.50%) and the excellent and good rate of fracture function recovery(95.00%) in the combined group were greatly higher than those in the control group(80.00%,75.00%)(P<0.05); the incidence of complications such as osteonecrosis in the combined group(7.50%) was greatly lower than that in the control group(27.50%)(P<0.05). Conclusion   CT three-dimensional reconstruction technology applied to the treatment of unstable pelvic fracture injury with anterior sacroiliac joint plate can effectively shorten the operation time,reduce the pain of patients,and promote postoperative recovery,which is safe and effective.
