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.
我们报告了一例类风湿性关节炎患者，该患者接受了使用自体跟骨骨移植的距舟关节融合术。同时，取骨部位的骨缺损用ReBOSSIS-J[70%β-磷酸三钙和30%聚（L-丙交酯-共-乙交酯）]（日本神奈川县ORTHOREBIRTH有限公司）进行填充，这是一种合成的可生物吸收骨缺损填充材料，其操作特性类似于棉球。术后一周材料吸收和新骨形成就已开始。术后26天时移植骨向宿主骨小梁的转化几乎完成。证实了移植骨非常快速的反应性吸收、新骨形成修复以及随后向宿主骨小梁的大部分转化。ReBOSSIS-J似乎有助于足踝手术后早期足跟负重锻炼。此外，还可预期预防跟骨骨移植取骨部位的骨折。
