acetabular dysplasia
Pronunciation: as-eh-TAB-yu-lar dis-PLAY-zha
Developmental abnormality of the hip socket resulting in inadequate coverage of the femoral head.
Full Definition
Acetabular dysplasia refers to abnormal development of the acetabulum (hip socket) that results in inadequate coverage and containment of the femoral head. This condition can range from mild undercoverage to severe dysplasia with subluxation or dislocation. It may be present at birth (developmental dysplasia of the hip) or develop later due to growth disturbances. The shallow acetabulum leads to abnormal hip mechanics, increased joint stress, and predisposition to early arthritis. Treatment varies from observation and bracing in infants to complex reconstructive surgery in adults.
Usage
Usage note: Often abbreviated as DDH (developmental dysplasia of the hip) in pediatric contexts.
