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 Preciceยฎ 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 surgeonsโ€™ 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.

โ€œTwo 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.โ€

Jaqueline

Iโ€™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

โ€œI feel incredibly straighter and moving like Iโ€™ve never moved before. Iโ€™m running finally and trying to get stronger. โ€ฆ Thank you so much and I am so glad I got to do this with you! Youโ€™ve changed my life.โ€

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 wasย  the heart.
And the hope.
And the will.
And I believe, there will never be the โ€œwonโ€™tโ€ or โ€œcanโ€™t.โ€

With deepest gratitude from,

Just a mother who loves her son

Aviva,
Mother of Patient, Zachary

โ€œIโ€™m in Sedona this week and have done 30+ miles of hikes and climbs with hundreds of feet of elevation. I couldnโ€™t have done this 1-2 years ago. Thank you for helping get me to this place!โ€

Sara
Patient of Dr. Rozbruch

โ€œI 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.โ€

“It amazes me that my knees donโ€™t even creak and crack, let alone grind. But even more amazing to me is that my knees no longer knock! โ€ฆ After living with knock knees for 62 years, I am still adjusting to this new sensation.โ€

Karen
Patient of Dr. Rozbruch

Todayโ€™s feature is a very dramatic #limbtrauma story. Mr S had an accident overseas where he lost part of his tibia. He convinced the doctors not to perform #amputation and was flown for care with me by @vitalone_air_medical and #refuahhelpline . He arrived in the temporary fixator which I converted to a circular frame for cable bone transport. Look at the upper green arrow showing the growing bone, and the red arrow showing the empty gap being filled. He made good progress initially, but after another overseas vacation resulted in additional infection, a temporary nail was needed to let the skin recover. Eventually, a second frame could be applied to complete the healing process by providing compression and aligning the bone position. As his bone became more stable he could also walk on it to further improve his bone healing. Finally, a CT scan showed the bone was healing enough to remove the frame for good and stabilize him with a nail. This is him walking today. We succeeded! We saved his leg from amputation and got him to walk this well!

This patient came to me after an initial attempt at reconstructing a femoral defect, but her leg was deformed and short so she knew there was a problem.

Today is an example of relatively common #limbtrauma . This woman had a refrigerator fall on her and sustained a tibial plateau #fracture . Initially she was nervous when I informed her that surgical care was recommended. But as her CT shows, there was a big step off and she would not recover well without surgery. I performed a typical lateral exposure and leveled her tibial plateau and placed a plate and screws. At three weeks her motion was excellent and we started light weight bearing. Now at three months, she remains pain free and walks excellently!
