Abstract

The aim of this chapter is to presents the role of allografts and bone substitutes. Allografts provide one such modality and can overcome the issue of longevity and durability (one of the major shortcomings of metallic reconstruction devices) as they are biologic and may be progressively incorporated by the host. Osteoarticular allografts and allograft prosthesis composite (APC) have been used for their biological properties such as providing attachments for muscle and ligaments; strut allografts have been applied to enhance mechanical stability of the reconstruction and morselized allografts have been utilized to fill the voids created consequent to curettage. Depending upon the type, size and the location of defect, allografts can be used in the following forms like osteoarticular allografts, intercalary allografts, allograft-prosthesis composites, morselized allografts, and allograft struts. Complications of reconstructions using allografts in musculoskeletal tumors are also discussed in this chapter.
