This study reported the case of a 42-year-old woman with traumatic ipsilateral critical bone defect of right femur and tibia after a motor accident. Three-dimensional (3D) printed porous titanium scaffolds were innovatively used to reconstruct this challenging situation. The initial stability was safe enough for early exercise and partial weight bearing. The 26-month follow-up showed osseous integration of the prosthesis-bone interface with short-term satisfactory clinical result.
The custom-designed 3D-printed porous scaffold has the potential to become an effective option for reconstructing the segmental irregular-shaped bone defect.
本研究报告了一例车祸后右侧股骨和胫骨同侧严重创伤性骨缺损的 42 岁女性病例。创新性地使用了三维（3D）打印多孔钛支架来重建这种具有挑战性的情况。初始稳定性足以确保早期运动和部分负重的安全性。26 个月的随访显示假体-骨界面具有骨整合，短期临床效果满意。
定制设计的 3D 打印多孔支架有可能成为重建节段性不规则形状骨缺损的有效选择。
