If CDH is unilateral, then operative reduction is preferred. If the head is reduced but there is poor coverage, then a bony roof should be constructed. This is achieved by repositioning the acetabulum and entire innominate bone - a Salter or innominate osteotomy - or constructing a shelf in the acetabulum.

If there has been marked anteversion of the femoral head, then this may be corrected with a de-rotational osteotomy of the femur.

In a bilateral dislocation, operative reduction is only undertaken if the deformity is severe.

After the age of 11, operations are generally only carried out if pain exists: possibilities include total hip replacement and arthrodesis.
