We report a case involving a 21-year-old woman who sustained a Grade III open pilon fracture of the left ankle during a motor vehicle accident that resulted in a 12-cm critical-sized bone defect (CSD) that was successfully treated with a three-dimensional (3D) printed titanium alloy (Ti-6Al-4V) cage, a tibiotalocalcaneal intramedullary nail, and autogenous and allograft bone. The patient's reported outcome measures were comparable with those reported for non-CSD injuries at 3-year follow-up. The authors conclude that 3D printed titanium cages offers a unique approach to traumatic limb salvage for tibial CSD.
3D printing offers a novel solution to CSDs. To the best of our knowledge, this case report details the largest 3D printed cage, to date, used to treat tibial bone loss. This report describes a unique approach to traumatic limb salvage with favorable patient-reported outcomes and evidence of radiographic fusion at a 3-year follow up.
我们报告一例涉及一名21岁女性的病例，该女性在机动车事故中遭受左踝III级开放性pilon骨折，导致12厘米的临界尺寸骨缺损（CSD），通过三维（3D）打印钛合金（Ti-6Al-4V）笼、胫距跟髓内钉以及自体骨和异体骨成功治疗。患者报告的结果指标在3年随访时与非CSD损伤报告的结果指标相当。作者得出结论，3D打印钛笼为胫骨CSD的创伤性肢体挽救提供了一种独特的方法。
3D打印为CSD提供了一种新的解决方案。据我们所知，本病例报告详细介绍了迄今为止用于治疗胫骨骨丢失的最大的3D打印笼。本报告描述了一种独特的创伤性肢体挽救方法，患者报告的结果良好，且在3年随访时有影像学融合的证据。
