Intercalary biologic reconstructions using allogenic bone grafts remain a useful option in orthopedic oncology; however, these reconstructions are prone to fractures, and treatment is usually required involving surgical interventions. Biologic activity of the implanted allografts remains minimal, but in some cases, spontaneous healing of the graft may occur. We present a report and discussion on two fractures and corrective osteotomy within the implanted allograft that healed with abundant callus without the need for additional surgery. In selected patients, allograft incorporation can be completed to a degree allowing for its biologic activity and spontaneous healing of fractures or osteotomy.
