Dr. George Holmes, foot and ankle orthopedic surgeon at Midwest Orthopaedics at Rush (MOR), removed the os trigonum bone in her ankle. Os trigonum Syndrome is very common in dancers who are always on pointe, which causes added stress to the ankle area. MOR foot and ankle orthopaedic surgeons treat many of the dancers in Chicago and throughout Illinois. Find out more at rushortho.com.
