Crowe's classification system has high practicality and reliability and it is commonly used to evaluate the degree of hip anatomy abnormality [17]. The Crowe classification considers the distance from the femoral head center to the inferior margin of the acetabulum (i.e., the acetabular teardrop) on a plain anterior-posterior (AP) radiograph to categorize the value of femoral head displacement.

Background Total hip arthroplasty (THA) is currently the best surgical option for hip osteoarthritis secondary to developmental hip dysplasia (DDH); it may be extremely challenging, because of the hypoplasic proximal metaphysis, pathological anteversion, and excessive cervico-diaphyseal angle of the neck at the femoral side.                   - usually do not have leg length inequality or loss of bone stock;                    - if cup is placed at level of true acetabular then a subtrochanteric shortening osteotomy is often required;                   - anterior and posterior columns are intact;  Keywords: Developmental dysplasia of the hip, Pelvic incidence, Severity of DDH, Crowe                   - Treatment of Crowe IV high hip dysplasia with total hip replacement using the Exeter stem and shortening derotational subtrochanteric osteotomy.
