Which Region of the Hip is Affected by Developmental Dysplasia

Question

Which region of the hip is affected by developmental dysplasia of the hip?
A) ischial tuberosity
B) ischial ramus
C) obturator foramen
D) greater sciatic notch
E) acetabulum

Accepted Answer

Developmental Dysplasia of the Hip (DDH) affects the acetabulum, which is the socket in the pelvis where the head of the femur (thigh bone) fits. DDH occurs when the acetabulum is shallow or underdeveloped, making it difficult for the femoral head to fully rest in the socket.
