Clinical observation of minimally invasive surgery for unstable pelvic fractures assisted by three-dimensional(3D)printing technology
Objective To analyze the clinical efficacy of the combination of three-dimensional(3D)printing technology and minimally invasive surgery in the treatment of unstable pelvic fractures.Methods A total of 40 patients with unstable pelvic fractures treated at Jiangsu Provincial People's Hospital and Liyang People's Hospital from January 2019 to September 2022 were selected as the subjects of the study.All patients were treated with minimally invasive percutaneous anterior pelvic ring internal fixation(Infix)assisted by 3D printing technology,and some patients with posterior ring instability were treated in conjunction with plate internal fixation.Surgical-related data were collected,including time of operation,blood loss,damage to important tissues,fracture healing,and postoperative functional recovery.The scores for fracture reduction and limb function were measured during the follow-up process.Results The wounds of the 40 patients healed at the first stage with-out wound infection.The average time from injury to surgery was(6.0±1.5)days;the time of operation for pelvic fracture fixation was 30 to 95 minutes,with an average of(60.8±5.9)minutes;the average intraoperative blood loss was(30.6±11.5)mL;the fracture healing time was(12.8±2.6)weeks.According to the Matta criteria for assessing the quality of fracture reduction:33 cases were excellent(82.5%),and 7 cases were good(17.5%).Besides,the limb function assess-ment results based on the Majeed criteria are as follows:30 cases were excellent(75.0%),and 10 cases were good(25.0%).Conclusion 3D printing technology-assisted minimally invasive surgery internal fixation can better assess the pa-tient's pelvic fracture condition preoperatively,which is beneficial for modeling,can shorten the time of operation,reduce in-traoperative blood loss,promote positioning accuracy,and ultimately achieve better surgical outcomes.
