Abstract：
We present the case of a patient with rheumatoid arthritis who underwent talonavicular joint fusion using an autologous calcaneal bone graft. At the same time, the bony defect at the harvest site was supplemented with ReBOSSIS-J® [70% β-TCP and 30% poly(L-lactide-co-glycolide)](ORTHOREBIRTH Co. Ltd., Kanagawa, Japan), a synthetic bioresorbable bone void filler for the repair of bony defects with handling characteristics similar to a cotton ball. Material resorption and new bone formation had already started one week postoperatively. Transposition to host bone trabeculae was almost completed by 26 days postoperatively. Very rapid reactive graft resorption, repair with new bone formation, and subsequently, most of the transformation to host bone trabeculae were confirmed. ReBOSSIS-J® appears feasible to contribute to early heel weight-bearing exercise after foot or ankle surgery. In addition, preventing the fracture at the harvesting site of the calcaneal bone graft can also be expected.
摘要：
我们介绍了一名类风湿关节炎患者的病例，该患者使用自体跟骨移植进行了距骨关节融合。同时,收获部位的骨缺损用ReBOSSIS-J®[70%β-TCP和30%聚(L-丙交酯-共-乙交酯)](ORTHOREBIRTH有限公司，神奈川,Japan),一种合成的生物可吸收骨空隙填充剂，用于修复骨缺损，具有类似于棉球的处理特性。术后一周材料吸收和新骨形成已经开始。术后26天几乎完成了与宿主骨小梁的转座。非常快速的反应性移植物吸收，修复新骨形成，随后,确认了大部分向宿主骨小梁的转化。ReBOSSIS-J®似乎可以促进足部或踝关节手术后的早期足跟负重锻炼。此外,还可以预期防止跟骨移植物的收获部位的骨折。
