DEVICE FOR PREVENTION avascular necrosis in the surgical treatment of congenital hip dislocation

摘要

The utility model is to maintain a constant hip joint gap when changing the spatial position of the acetabulum with hip head centered providing stable fixation and the possibility of separately controlling the position of the dynamic joint elements. This result is achieved in that the fixation is performed separate acetabular fragment and femoral joint component. For this purpose, the device is introduced into the intermediate arc support, an additional pair of cantilever displacement spokes and hub, connecting to an intermediate arcuate support supports the femoral component.
