Limb-preserving surgery in young children suffering malignant bone tumor of the femur is challenging due to the specific anatomical conditions. Extendable tumor endoprostheses are often oversized, while custom-made endoprostheses do not provide the intraoperatively required variability regarding reconstruction length. Allo- and autograft replacements, on the other hand, show high complication and revision rates. We report a novel reconstructive procedure after resection of malignant bone tumors of the femur in young children, and present our preliminary results of this technique.

MUTARS® Humero pro 股骨置换术：幼儿股骨恶性骨肿瘤切除术后的一种新型重建手术

由于特定的解剖条件，对患有股骨恶性骨肿瘤的幼儿进行保肢手术具有挑战性。可扩展的肿瘤内置假体通常尺寸过大，而定制的内置假体无法提供术中所需的重建长度可变性。另一方面，同种异体和自体移植物的并发症和翻修率很高。我们报告了一种在幼儿股骨恶性骨肿瘤切除术后的新型重建手术，并介绍了我们对该技术的初步结果。
