Our practice offers 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. Our surgeons 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. Our surgeons 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.

Mr R has long managed #hiv , with associated neuropathy. A prior fracture would not heal and his ankle developed increasing deformity and skin ulceration. He opted for simultaneous #amputation with #osseointegration with @osseointernational OPL with my partner Dr Rozbruch, and now walks excellently thanks to PT help from @waikwong_dpt and prosthesis care from @hkafedzic using a @proteorusa Rush Rogue foot! His skin does look unusual, but has not needed further surgical care. Here is how he describes his experience:
