Clinical effect of 3D printing technology assisted medial and lateral locking plate internal fixation in the treatment of complex tibial plateau fractures
Objective To observe the clinical effect of 3D printing technology assisted medial and lateral locking plate internal fixation in the treatment of complex tibial plateau fractures.Methods A total of 80 patients with complex tibial plateau fractures admitted from June 2020 to June 2022 were selected as the research objects.The patients were divided into control group and observation group by random number table method,with 40 cases in each group.Both groups were treated with medial and lateral locking plate internal fixation,the control group completed the operation according to the results of preoperative imaging examination and the experience of the surgeon,and the observation group used 3D printing technology to assist in the operation.The therapeutic effects of the two groups were compared.Results The operation time,fracture healing time and full weight-bearing time of the observation group were shorter than those of the control group,and the intraoperative blood loss and fluoroscopy times were less than those of the control group(P<0.05).At 1,3 and 6 months after operation,the Rasmussen radiological score of the observation group was higher than that of the control group(P<0.05).At 1 and 3 months after operation,the tibial plateau varus angle and tibial plateau posterior slope angle in the observation group were greater than those in the control group(P<0.05).At 1 and 3 months after operation,the Hospital for Special Surgery Knee Score(HSS)and Fugl-Meyer Assessment(FMA)scores of the observation group were higher than those of the control group(P<0.05).Conclusion 3D printing technology assisted medial and lateral locking plate internal fixation in the treatment of complex tibial plateau fractures can improve the surgical effect,but also help to improve the quality of fracture reduction,which is worthy of clinical promotion.
