Three-dimensional (3D) reconstruction has been used for various diseases, but few reports have described its application in pelvic reconstruction after removal of giant chondrosarcoma. Case reports describing the clinical application of personalized 3D-printed titanium implants are needed for future clinical reference. We herein describe a 29-year-old woman with a giant chondrosarcoma treated with a personalized 3D titanium implant. The surgery was successful, and the patient recovered with significant pain relief and good functional recovery after the surgery. No implant-related complications occurred during the 12-month follow-up. The current case represents successful application of 3D printing technology to the treatment of a massive bone defect due to the removal of a giant osteoporotic tumor.
Personalized 3D titanium implants can be used in the reconstruction of massive bone defects after the removal of giant pelvic sarcomas. The methodology and results described in the current case report can be a used as reference in the treatment of similar cases in future.
三维（3D）重建已应用于各种疾病，但很少有报道描述其在巨大软骨肉瘤切除后骨盆重建中的应用。需要有描述个性化 3D 打印钛植入物临床应用的病例报告，以供未来临床参考。我们在此描述了一例 29 岁女性患者，其患有巨大软骨肉瘤，采用个性化 3D 钛植入物进行治疗。手术成功，患者术后疼痛明显缓解，功能恢复良好。在 12 个月的随访中，未发生与植入物相关的并发症。本病例代表了 3D 打印技术在治疗因巨大骨质疏松性肿瘤切除而导致的大块骨缺损方面的成功应用。
个性化 3D 钛植入物可用于巨大骨盆肉瘤切除后大块骨缺损的重建。本病例报告中描述的方法和结果可作为未来治疗类似病例的参考。
