The Role of Distraction Osteogenesis in Limb Salvage for Tumors.

Abstract

Modern technology and advances in medicine have facilitated increasing rates of limb salvage in the treatment of sarcomas. Orthopedic oncologists have a wide array of reconstruction options for limb salvage, ranging from allografts to endoprosthesis reconstruction. Limb lengthening is another option available to an orthopedic oncologist faced with bony defects and limb length discrepancies following resection. This review provides a brief history of limb lengthening, the principles of distraction osteogenesis, and current applications in orthopedic oncology. Considering the complications and challenges associated with the lengthening process, appropriate patient selection and thorough patient counseling is key to optimizing outcomes.
