Staged upper and lower limb lengthening performing bilateral simultaneous surgery of the femur and tibia in achondroplastic patients.

Introduction: Surgical lengthening and angular correction of the limbs are an option for treating the orthopedic clinical manifestations in patients with achondroplasia. This study assesses a staged limb lengthening protocol, performing simultaneous bilateral lengthening of the femur and tibia (stage I [S1]), and humeral lengthening (stage II [S2]).

Materials And Methods: Twenty-one achondroplastic patients were included in this study, and 106 segments (34 femurs, 34 tibias and 38 humeri) were lengthened.
