Abstract
Structural allograft bone plays a role in orthopedic surgery. Our purpose is to describe the methods of using structural allograft in extremity reconstruction surgery in patients with osteogenesis imperfecta (OI) and create a classification of usage with a single-center review of OI extremity cases from January 2002 to February 2017. Structural allograft was used in 19 bone segments in 15 patients with type III OI. Four categories of usage were defined: (1) interpositional, (2) onlay, (3) inlay, and (4) blocking to prevent rod migration. The mean time to incorporation was 5.4 months (range 1-16). Structural allograft bone incorporates into OI bone and may be a supplement to intramedullary fixation.
