Welton K, Jesse M, Kraeutler M, Garabekyan T, Mei-Dan O. < The normal acetabulum of the cat is generally shallower than the acetabulum in the dog. Comprehensive Clinical Evaluation of Femoroacetabular Impingement: Part 2, Plain Radiography. Mannava S, Geeslin A, Frangiamore S et al. Surgical Treatment of Developmental Dysplasia of the Hip. Orthopaedics & Traumatology: Surgery & Research. Specially positioned hip x-rays and special palpation methods that determine abnormal hip joint laxity, both. will be reduced in comparison with a normal dog due to the arthritic new bone. Outcomes of Modified Dega Acetabuloplasty in Acetabular Dysplasia Related to Developmental Dislocation of the Hip. CHD is diagnosed by a combination of two methods. Does Shelf Acetabuloplasty Influence Acetabular Growth and Remodeling? Clin Orthop Relat Res. The first three categories (excellent, good and fair) are generally considered normal. Measurement of Angle After Total Hip Replacement. Hip radiographs were taken by a veterinarian with the dog in the hip. Measuring Acetabular Dysplasia in Plain Radiographs. Large breed dogs are most commonly diagnosed, however small breed dogs and cats also. ![]() First described in the 1930's, it continues to affect millions of dogs worldwide.

What are the treatment options for hip dysplasia Depending on your pet’s age, physical condition, and degree of hip pain/lameness, there are several surgical treatment options. The head of the femur (arrow) is seated deeply within the acetabulum, indicating excellent hip joint congruity. Having the center beam above or below the pubis can alter the measurement due to geometric distortion. Radiographs (X-rays) of a normal dog’s pelvis and hips. When the angle is between the upper end of the normal range and an increased acetabular angle the terms "borderline" or "indeterminate" can be used 6,7. The acetabular angle using the Hilgenreiner line should be 42º 6 or ≥45º 7. This, of course, shifts the horizontal line inferiorly and changes the value of the angle ref. In adults, where the triradiate cartilages are fused and therefore inapparent, the horizontal plane of the pelvis defined as the inferior margin of the pelvic teardrop is used instead 7. ![]() In children, the angle is formed by a horizontal plane of the pelvis defined by a line connecting both triradiate cartilages ( Hilgenreiner line) and a second line that extends through to the lateral aspect of the acetabular roof 7,8.
