People who've heard of hip dysplasia often think of it in connection with babies and dogs. One baby in 1, is born with hip dysplasia, but only 12 percent of those have unstable hips past the age of 2 months [source: Ramsey ]. And hip dysplasia is common in dogs , particularly in large breeds. Hip dysplasia doesn't occur only in infants and pets, though. People, particularly women , can be diagnosed with and treated for hip dysplasia as adults. Hip dysplasia is an abnormal condition affecting the hip socket, or acetabulum , and the thighbone, or femur.
Assessment of adult hip dysplasia and the outcome of surgical treatment

Although chronic hip pain is often associated with aging, the appearance of this symptom in adolescents and young adults may be a sign of hip dysplasia , a condition in which one or more areas of the hip joint have not developed normally. Articular cartilage, a smooth protective tissue, lines the bones and limits friction between the bone surfaces during movement. In individuals with hip dysplasia, the acetabulum does not develop fully, making it too shallow to adequately contain and support the femoral head. When this abnormality is present, the ball and socket are misaligned and the labrum can end up bearing the forces that should be distributed throughout the hip. Also, more force is placed on a smaller surface of the hip cartilage and bone, resulting in arthritis over a number of years.
X-ray of hip dysplasia
Purpose: To perform a narrative review to report the differences in hip morphology and clinical outcomes between adult patients with frank hip dysplasia and BHD. Study design: Narrative review. Results: The search identified articles, of which 48 were considered relevant to this study after screening of titles and abstracts. Because the level of evidence obtained from this search was not adequate for systematic review or meta-analysis, a current concepts review on the diagnosis, hip morphology, and clinical outcomes of patients with frank hip dysplasia or BHD is presented. Conclusion: Adult hip dysplasia is most commonly diagnosed based on the LCEA; however, the LCEA is an unreliable sole marker for dysplasia, and additional radiographic parameters should be utilized.
Conventional radiography is the initial step in evaluating etiology of hip pain in any patient. In general, the AP pelvic and false-profile views provide the most useful information in radiographic assessment of acetabular dysplasia. The AP view of the pelvis is the single most important view in the evaluation of acetabular dysplasia and is the first radiographic step in the study of adult hip pain. Appropriate position is guaranteed when the coccyx and symphysis are aligned, obturator foramina have a symmetric appearance not rotation , and the tip of the coccyx is between 1 to 3 cm above the superior border of the pubic symphysis not tilt.
