Recent advances in limb lengthening. Part I: Clinical advances

Abstract

The discipline of limb lengthening has undergone numerous advances in recent years. An increased understanding of the biology of distraction osteogenesis, as well as technical advances, has made lengthening more feasible. However, significant problems remain unsolved, and complications--although less severe and long standing--still remain. Little is known about the effect of distraction on soft tissues. Lengthening in skeletally mature patients remains difficult. The myriad of conditions that require lengthening often confounds comparison of techniques. Uniform indications for limb lengthening may never exist, but increasing experience helps guide patient selection.
