Our surgeons offer surgical treatments for the correction of upper and lower limb deformities, length discrepancies, and injuries in adults and children. We help individuals with orthopaedic problems due to trauma, birth defects, infections or bone tumors. We use the best tools available today including Precice® motorized magnetic lengthening and compression nails, automated hexapod external fixation, osseointegration limb reconstruction, patient specific anatomic plating, and more. These tools are combined with our surgeons’ expert surgical techniques to achieve the optimal results patients desire.
We perform arm and leg lengthening, limb malalignment correction, repair of bone non-unions, and treat hip, knee and ankle arthritis with distraction, fusion, or replacement. Along with limb length discrepancy, we correct genu valgum, commonly known as knock knee, and genu varum, or bowleg. We are experts at both limb salvage and amputation reconstruction. Whether patients are suffering from arthritis, genetic deformity, bone tumors, or the effects of a traumatic accident, the Limb Lengthening & Complex Reconstruction Service of Hospital for Special Surgery is ready to get them on the road to recovery and an improved quality of life.

Five-year-old Lyle had extramedullary lengthening of his femur using an internal lengthening nail. This technique is ideal for this age group and allows us to avoid an external fixator. Adjust 10 weeks after a 2.5 cm lengthening, he is walking full weight-bearing and has made great bone.#hsskids #hssllcrs #hsslimblengthening #precicenail #pediatricorthopedics @hspecialsurgery @limblengtheningreconstruction
