Double osteotomy of the pelvis for treatment of an anterior hip subluxation in a 9-year-old child with cerebral palsy: a variation of the Salter osteotomy.

Treatment with an unconventional double osteotomy of the pelvis in a 9-year-old girl with recurrent anterior hip subluxation after hip reconstruction in cerebral palsy is presented. Classical Pemberton or Salter osteotomy is effective for superolateral acetabular dysplasia, but corrections in the anterior or posterior direction are limited. In this case, double osteotomy of the pubic and iliac bone allowed better coverage in the anterior part of the acetabulum. The bone provided sufficient elasticity to achieve the desired correction without an ischial cut, therefore providing more stability of the pelvis.
