Pelvic osteotomy relates to an orthopedic treatment for developmental acetabular dysplasia of the hip.
The main purpose of pelvic osteotomy is the prevention of early degenerative changes by stabilization of the hip and redistribution of joint loading. It is obtained by surgical reshaping/remodeling or redirection of an abnormal acetabulum.
Types
Reshaping osteotomy (performed when the triradiate cartilage is open):
Dega
Redirectional osteotomy (orientation of the acetabulum is changed by transection of the innominate bone):
Salter (single innominate osteotomy)
Sutherland (double innominate osteotomy)
Steel, Tonnis, or Carlios (triple innominate osteotomy)
Ganz (periacetabular)
