Limb Lengthening

Hospital for Special Surgery ranked #1 in US for orthopedics 14 years in a row by US News & World Report.

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.

It was not the collagen that helped Zachary.
It was you.
And it was him.
And somewhere in that whole powerful mix of skin and bones and skill and science, there was the heart.
And the hope.
And the will.
And I believe, there will never be the “won’t” or “can’t.”

“I’m in Sedona this week and have done 30+ miles of hikes and climbs with hundreds of feet of elevation. I couldn’t have done this 1-2 years ago. Thank you for helping get me to this place!”

Sara

Patient of Dr. Rozbruch

“I know how much you love what you do. It is evident in the way that you have cared for Zachary. The way Zachary has improved under your care. Improved is certainly an understatement! You have performed miracles with him. And everyone around you has been part of the process.”

Susan

“I just did a 10mile walk in support of the jimmy fund. I was worried about using my legs for such a long distance. But they were completely fine, and they exceeded my expectations! I can’t believe I’m almost back to normal (90-95% there). Overall, I wish I did this 20 years ago. Thanks again.”

Just returned from #LLRS annual meeting in Montreal, and it was fantastic! Our group from #hssllcrs @hspecialsurgery presented 6 podium presentations. We were very active presenting and moderating academic sessions. Great to see colleagues, previous fellows, and friends. I was very proud of my fellow from 2013 Mitch Bernstein who was the LLRS President and ran an awesome conference @limblengtheningreconstruction #hsslimblengthening @reifmd @all4ortho #llrs2026
