Quick Transposition of ReBOSSIS-J® to the Host Bone Trabeculae Within One Month After Supplementing to the Harvest Site on the Calcaneus for Autologous Bone Grafting in a Rheumatoid Arthritis Case

We present the case of a patient with rheumatoid arthritis who underwent talonavicular joint fusion using an autologous calcaneal bone graft. At same time, bony defect at harvest site was supplemented ReBOSSIS-J® [70% β-TCP and 30% poly(L-lactide-co-glycolide)](ORTHOREBIRTH Co. Ltd., Kanagawa, Japan), synthetic bioresorbable void filler for repair defects handling characteristics similar to cotton ball. Material resorption new formation had already started one week postoperatively. Transposition host trabeculae almost completed by 26 days Very rapid reactive graft resorption, formation, subsequently, most transformation were confirmed. appears feasible contribute early heel weight-bearing exercise after foot or ankle surgery. In addition, preventing fracture harvesting can also be expected.
