Two types of hip disease, acetabular dysplasia
and pincer femoro-acetabular impingement, are associated with morphological abnormalities of the acetabulum, including acetabular diameter, depth and orientation (Zeng et al., 2012).
(7) reported a high incidence of cam and pincer impingement lesions, as well as acetabular dysplasia
, in professional ballet dancers.
The radiographs detected platyspondyly, thoracolumbar scoliosis, dysplastic femoral epiphysis and metaphysis, mild acetabular dysplasia
, and dysplastic radial epiphysis and radial and ulnar metaphysis.
For instance, there is associated adaptive shortening of the soft tissues, capsular constriction, increased femoral anteversion, acetabular dysplasia
, presence of obstructing structures such as the fibrofatty tissue in the acetabulum, hypertrophied ligamentum teres, the transverse acetabular ligament and fixed inversion of limbus.1-4,13,14 Femoral diaphyseal shortening is superior to traction as an aid in operative reduction of DDH in older children.
(37) His data suggested that 39% of those with osteoarthritis of the hip exhibited radiographic evidence of acetabular dysplasia
(20%) or "tilt deformity" (19%), which was later defined as a cam.

The etiology of hip disease in these 8 revisions, included five acetabular dysplasia
, one avascular necrosis and systemic lupus erythematosus, one multiple epiphyseal dysplasia, and one primary osteoarthritis.
 This locus has not been linked to other forms of familial acetabular dysplasia
, indicating that BHD is a distinct disorder.
Therefore when the parents seek treatment it is often too late and it then needs major surgical intervention due to adaptive shortening of the extra-articular soft tissues acetabular dysplasia
and increasing femoral anteversion.
was noted and Acetabular index was calculated and found to be 45[degrees].
and coxa valga occur in approximately 25% of HME patients .
