Studies have demonstrated that acetabular dysplasia leads to degenerative changes over time, likely secondary to mechanical factors and related to increased contact stresses.
While there is considerable evidence that radiographic acetabular dysplasia leads to secondary degenerative joint disease, (15,58) there are no predictive radiographic parameters.
The radiographic features of adult hip dysplasia may range from subtle acetabular dysplasia to complete dislocation of the femoral head from the native acetabulum.
The anterior-posterior (AP) view of the pelvis is the single most important view for defining acetabular dysplasia.
Byrd and Jones published a report in 2003 of 48 patients who underwent hip arthroscopy for intraarticular pathology and were retrospectively determined to have acetabular dysplasia.
5,6,74,76) Acetabular dysplasia typically results in intraarticular pathology, and hip arthroscopy may provide an opportunity to address this pathology.
Over the years, we learned that acetabular dysplasia is not a uniform anterolateral deficiency of femoral head coverage but is a diversity of pure or combined anterior, lateral, and posterior coverage problems; the most important being retroversion of the acetabulum as seen in one out of six dysplastic hips.
Further studies revealed that the anterior head-neck junction in acetabular dysplasia frequently has no waisting contour, eventually leading to impingement after the acetabulum is corrected.
Retroversion is not only seen together with acetabular dysplasia, but found even more frequently in non-dysplastic hips where it is considered to be more a torsional problem of the hemipelvis than of the acetabulum.
9) Viewing the spectrum of our surgical procedures to preserve the natural hip joint, periacetabular osteotomy for acetabular dysplasia is the procedure that leads to the most predictable results.
Morphologic characteristics of acetabular dysplasia in proximal femoral focal deficiency.
We can suggest that, if a considerable improvement in AA cannot be observed by 1 year postoperatively or an abnormal AA persists after 7 to 8 years of age, the surgeon should be on the alert for a possible further development of acetabular dysplasia and consider performing an osteotomy to reorient the acetabulum in such hips.
Acetabular dysplasia after treatment for developmental dysplasia of the hip.
Radiographs showed mild acetabular dysplasia, coxa vara, and shortening of the femoral neck (Fig.
At the last follow-up, radiographs showed mild acetabular dysplasia, shortening of the femoral neck, and a high position of the greater trochanter.
