3D打印技术辅助微创复位螺钉内固定治疗老年Sanders Ⅱ～Ⅲ型跟骨骨折患者的疗效
Efficacy of 3D printing-assisted minimally invasive reduction and screw internal fixation in elderly patients with Sanders type Ⅱ-Ⅲ calcaneal fractures
摘要
Abstract
Objective:To investigate the efficacy and safety of 3D printing-assisted minimally invasive reduction and screw internal fixation in elderly patients with Sanders type Ⅱ-Ⅲ calcaneal fractures.Methods:A retrospective analysis was conducted on 100 elderly patients with calcaneal fractures who were treated at the 920th Hospital of the Joint Logistics Support Force of the People's Liberation Army of China from May 2021 to May 2024.Patients were divided into the 3D printing group(n=43,treated with 3D printing-assisted minimally invasive reduction and screw internal fixation)and the conventional group(n=57,treated with standard minimally invasive reduction and screw internal fixation).Perioperative indicators,subjective pain perception,postoperative functional scores,quality of life,calcaneal morphology at final follow-up,and complications were compared between the two groups.Results:The 3D printing group demonstrated significantly shorter operative time,smaller incision length,fewer intraoperative fluoroscopies,reduced blood loss,shorter length of hospital stay,and lower treatment costs compared to the conventional group(P<0.05).The Visual Analogue Scale(VAS)scores on 1-4 days after surgery were significantly lower in the 3D printing group(P<0.05)than those in the conventional group.Both groups showed progressive improvements in the American Orthopaedic Foot and Ankle Society(AOFAS)Ankle-Hindfoot Score,Maryland foot function score,and Short Form-36(SF-36)quality of life score over time.However,the 3D printing group showed higher scores at 1,3,and 6 months after surgery(P<0.05),and greater restoration of Böhler's angle,Gissane's angle,and calcaneal height,along with narrower calcaneal width compared to the conventional group(P<0.05).No significant difference was observed in overall complication rates between the two groups(P>0.05).Conclusion:The application of 3D printing technology in minimally invasive reduction and screw internal fixation for elderly patients with Sanders type Ⅱ-Ⅲ calcaneal fractures had significant short-term benefits,which could effectively alleviate pain,improve postoperative functional outcomes,and enhance quality of life.关键词
