总结3D打印个性化假体在儿童股骨远端骨肉瘤保肢手术的短期疗效。
方法
2
总结重庆医科大学附属儿童医院2021年5月至2025年2月行3D打印个性化假体股骨远端骨肉瘤保肢手术的19例患儿的疗效,其中9例为保骺组,行3D打印个性化保骺假体植入术;10例为铰链组,行3D打印个体铰链式假体植入术。收集并分析患者的基本临床资料、围术期资料和随访情况。
结果
2
19例患儿均按术前规划完成手术,术后患儿膝关节功能恢复良好。其中保骺组(
n
=9):男性患儿8例,女性患儿1例,年龄(11.05±2.75)岁,随访时间(21.67±15.87)月,无瘤生存8例,死亡1例,美国骨骼肿瘤协会(Musculoskeletal Tumor Society, MSTS)评分为(27.56±1.33)分。铰链组(

在儿童股骨远端骨肉瘤保肢治疗中,3D打印个性化假体植入术术后短期随访结果满意。
Objective To evaluate the short-term efficacy of 3D-printed customized prostheses in limb-salvage surgery for pediatric distal femoral osteosarcoma. Methods A single-center retrospective study was conducted on the outcomes of 19 eligible children at the Affiliated Children's Hospital of Chongqing Medical University from May 2021 to February 2025. Among them
9 cases were in the epiphysis-preserving group and received 3D-printed personalized epiphysis-preserving prosthesis implantation; 10 cases were in the hinge group and underwent 3D-printed individual hinge prosthesis implantation. Their basic clinical data
perioperative data
and follow-up information were collected and analyzed. Results All the 19 subjected patients completed the surgeries as preoperatively planned. The knee joint function of the children recovered well after surgery. In the epiphysis-preserving group
there were 8 males and 1 female
at an average age of 11.05±2.75 years. During a follow-up time of 21.67±15.87 months
8 cases obtained disease-free survival
with a mean Musculoskeletal Tumor Society (MSTS) score of 27.56±1.33
and the left 1 case deceased. The hinge group included 4 males and 6 females
at an age of 10.12±2.30 years
and they were followed up for 22.30±11.23 months. For the 7 cases with disease-free survival
their MSTS score was 25.30±2.21
and the other 3 cases dead. Conclusion In the limb salvage treatment of children with osteosarcoma in the distal femur
3D-printed personalized prosthesis implantation achieves satisfactory short-term outcome.
