MeshID =Protrusio acetabuli is an uncommon defect of the
acetabulum . The acetabulum is the socket that receives thefemoral head to make the hip joint. It is composed of threebones , the ilium, theischium and the pubis. The socket is too deep and may protrude into thepelvis . cite journal |author=Van De Velde S, Fillman R, Yandow S |title=The aetiology of protrusio acetabuli.

Protrusio acetabuli is divided into two types, primary and secondary.
"Primary" protrusio acetabuli
* Characterized by progressive protrusio in middle aged women
* May be associated with OA
* May befamilial "Secondary" protrusio acetabuli
Causes include:
may be present bilaterally in
Paget's disease ,Marfan syndrome ,cite journal |author=Van de Velde S, Fillman R, Yandow S |title=Protrusio acetabuli in Marfan syndrome.

* Cuparthroplasty
*Septic arthritis
* Centralfracture dislocation
*Total hip replacement surgery igns and Symptoms
* May be
asymptomatic
* Limitation of joint range of movement is the earliest sign
* PainNatural course
The protrusio may progress until the femoral neck impinges against the pelvis.
Diagnosis
Diagnosis is made on the basis of an anteroposterior
radiograph of the pelvis that demonstrates a center-edge angle greater than 40 degrees and medialisation of the medial wall of the acetabulum past the ilioischial line.Treatment
Joint replacement surgery is indicated for severe pain or substantial joint restriction
