As to the ethiopathogeny of Scheüermann's disease there is no consensus about the
true cause of vertebral body wedging. It seems clear that the deformity of vertebral bodies is a
consecuence of osteochondral weakness in a growth period in which mechanic factors are involved.
This provides fundamentals of conservative treatment analvzing the results obtained with the
Milwaukee and New York braces. The results demostrate a clear adventage of Milwaukee brace for
upper kiphosis. On the other hand, low profile braces work well on curves with apex below T7,
although less wedge angle correction is obtained.
