Reverse-reamed Intercalary Allograft: A Surgical Technique

Abstract

Allograft reconstruction of large segmental intercalary bone defects after tumor resection is a well-accepted surgical technique. Although results generally have been satisfactory, nonunion at the allograft-host bone junction site remains a notable concern. Various reports have described attempts to enhance junctional healing with a variety of complex osteotomies, often complicating an already complex procedure. The use of an innovative reverse reaming technique can decrease the level of intraoperative difficulty mating the allograft-host junction and theoretically may improve junctional healing by enhancing stability and increasing the contact surface area.
