Dysplasia is a condition where there is a lack of coverage of the socket (acetabulum) over the ball (femoral head). When a person has a dysplastic hip, the body develops a labrum that is thicker and bulkier then normal, which predisposes it for tearing or injury.
Patients with hip dysplasia generally report feeling the hip gliding in and out of place. They are usually very flexible, with hypermobile hip joints.
Initial evaluation of a person suspected of hip dysplasia includes a physical exam and plain X-rays to view the extent of dysplasia. Treatment options vary and can include physical therapy focusing on strengthening the surrounding hip muscles and activity modifications.
If a patient’s hip is unstable, a peri-acetabular osteotomy (PAO) may be required, which involves creating more coverage of the femoral head with bone. Labrum injuries in the dysplastic hip may be treated arthroscopically.
