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.

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

“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.”

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.”

This is an email a patient sent to me today. This patient also has been a support person for another patient of mine. It's wonderful to have patients within one's practice who come to know and support one another.

Many of the patients I help have a formidable recovery process. It is part of the joy of choosing this specific specialty to provide support through the process. Surgeons never can care alone; these great experiences are routine only because every employee at @hspecialsurgery is also dedicated to patient care

Today’s featured patient is Ms M, a young woman who was struggling with short fourth toes, a condition called #brachymetatarsia . You can see here that the fourth metatarsal is not fitting the normal cascade of the toes, with the dotted line showing the deficit. She felt awkward walking and didn’t feel right in either of her feet. A common option is to use an external fixator to slowly lengthen the metatarsal, but this makes it difficult because a patient must adjust the fixator several times daily and cannot wear a regular shoe for several months. So instead, I inserted a bone graft from @stryker.orthopaedicinstruments which immediately provided the length she needed. This allowed her to walk on her feet the entire time her bones were healing. I have now removed the hardware stabilizing her bones and she feels much better in how she feels and also how she feels about herself!
