A 7-year-old boy presented with osteosarcoma of the ulna that required a transhumeral amputation. The patient completed neoadjuvant chemotherapy before surgery. To prevent bone overgrowth and improved prosthetic fitting, a modified amputation was performed with acute shortening and distal epiphysis preservation.
In this modified amputation, bone overgrowth was not seen and repeated surgeries for stump shaping were prevented. The modified technique enabled length for the prosthetic elbow and a wide stump for better fitting. In cases of transhumeral amputation in children, the modified technique should be considered.
一名 7 岁男孩患有尺骨骨肉瘤，需要进行肱骨截肢。该患者在手术前完成了新辅助化疗。为了防止骨过度生长和改善假肢适配，进行了改良截肢术，进行急性缩短和远端骨骺保留。
在这种改良的截肢术中，没有出现骨过度生长的情况，并防止了因残端塑形而进行的多次手术。改良技术为假肢肘部提供了长度，并为更好的适配提供了宽大的残端。对于儿童肱骨截肢病例，应考虑采用改良技术。
