3D打印辅助PMMA骨水泥髓内支撑在肱骨近端骨质疏松性骨折治疗中的应用
Application of 3D printing-assisted PMMA bone cement intramedullary support in the treatment of osteoporotic fractures of the proximal humerus
摘要
Abstract
Objective:Analyze the application of 3D printing-assisted polymethylmethacrylate(PMMA)bone cemented intramedullary support in the treatment of Neer Ⅱ,Ⅲ,and Ⅳ osteoporotic fracture of the proximal humerus.Methods:90 elderly patients with osteoporotic fractures of the proximal humerus who were treated with 3D printing-assisted PMMA bone cemented intramedullary support in General Healthcare Hanzhong 3201 Hospital from October 2021 to November 2023 were retrospectively selected and divided into the Neer Ⅱ fracture group(n=28),the Neer Ⅲ fracture group(n=37)and the Neer Ⅳ fracture group(n=25)according to the Neer classification,and the rehabilitation conditions of patients was observed.Results:The preoperative humeral neck-shaft angle of the affected side was all significantly smaller than that of the healthy side in the three groups(P<0.05),whereas the difference was not statistically significant at 6 months after surgery(P>0.05).The differences in humeral head height between intraoperative and postoperative 6-month measurements were all<5 mm in the three groups.VAS scores and Constant-Murley scores at different postoperative timepoints were all significantly lower than those befor surgery in the three groups(P<0.05),and the scores at different timepoints in pairwise comparisons showed significant differences(P<0.05).The scores on quality of life in all dimensions were significantly increased in the three groups at 6 months postoperatively compared with those before surgery(P<0.05).Conclusion:Application of 3D printing-assisted PMMA bone cement intramedullary support in treating elderly Neer type Ⅱ,Ⅲ,and Ⅳ osteoporotic fractures of the humerus can effectively promote the postoperative recovery and has a good application effect.关键词
