Our surgeons offer surgical treatments for the correction of upper and lower limb deformities and injuries in adults and children. We help individuals with orthopaedic issues due to trauma, birth defects, infections or tumors. Our aim is to use the best tools available today — from Taylor Spatial FramesTM to internal lengthening devices, such as the Precice® Intramedullary System and the newest technology, the Novos® Nail. These tools are combined with our doctors' expert surgical techniques to achieve results many patients have only dreamed of.

We perform arm and leg lengthening and deformity correction, repair bone nonunions, and treat knee and ankle arthritis with distraction, fusion, or replacement. We correct genu valgum, commonly known as knock knee, and genu varum, or bow leg. Whether patients are suffering from arthritis, genetic deformity or the after effect of a traumatic accident, HSS's Limb Lengthening & Complex Reconstruction Service is ready to get them on the road to recovery and a new life.
