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

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.

Conditions We Treat


“…it has been 2 years since I had my surgery and I am virtually pain free. Thank you very much for all the care and amazing support, it has truly been life altering.”

Luiz
Patient of Dr. Rozbruch

I just want to thank you from the bottom of my heart, you did such an incredible job, along with your attentiveness to my concerns and needs, being available whenever I had a question.

Austin
Patient of Dr. Reif

“Two years ago, before I came to you, I could never have imagined being in the position I am in now. What you and your team have done for me is truly priceless.”

Jaqueline
Patient of Dr. Rozbruch

I’m so proud that you are my physician, not only for your superb surgical skills, but also your charisma and compassion. You are honestly one of the most respectable and endearing persons in my life.

Jake
Patient of Dr. Rozbruch

“I feel incredibly straighter and moving like I’ve never moved before. I’m running finally and trying to get stronger. … Thank you so much and I am so glad I got to do this with you! You’ve changed my life.”

Kavi
Patient of Dr. Rozbruch

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.”

With deepest gratitude from,

Just a mother who loves her son

Aviva,
Mother of Patient, Zachary

“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.”

Zacharyt
Patient of Dr. Rozbruch

“I think of you everyday and I am so thankful to you. Because of you, Mark’s life has been changed forever.  Again thank you so much for all you have done.”

Susan
Wife of Dr. Rozbruch Patient

“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.”
