Protrusio acetabuli is an uncommon defect of the acetabulum. The acetabulum is the socket that receives the femoral head to make the hip joint. The hip bone of the pelvic bone/girdle is composed of three bones, the ilium, the ischium and the pubis. In protrusio deformity, there is medial displacement of the femoral head in that the medial aspect of the femoral cortex is medial to the ilioischial line. The socket is too deep and may protrude into the pelvis.^[1]

Classification

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 be familial

Secondary protrusio acetabuli

Causes include:

Femoral head prosthesis
Cup arthroplasty
Septic arthritis
Central fracture dislocation
Total hip replacement surgery

Protrusio acetabuli may also be thought of as unilateral or bilateral.

Unilateraly protrusio acetabuli

Tuberculous arthritis
Trauma
Fibrous dysplasia

Bilateral protrusio acetabuli

Rheumatoid arthritis
Paget disease
Osteomalacia

(Source Dahnert's Radiology)

In addition, protrusio acetabuli may be present bilaterally in Paget's disease, Marfan syndrome,^[2] rheumatoid arthritis, ankylosing spondylitis, and osteomalacia;

Signs and Symptoms

May be asymptomatic
Limitation of joint range of movement is the earliest sign
Pain

Natural course

The protrusio may progress until the femoral neck impinges against the pelvis.

Treatment

Arthroscopic surgery (or open joint surgery) is an effective treatment. Joint replacement surgery may be necessary in the case of severe pain or substantial joint restriction. Prominent trabeculae. * Normal sacro-iliac joints and symphysis pubis.

A new CT-based diagnostic method of protrusio acetabuli (PA) was introduced. However, prevalence of PA by this method and correlation between PA and other manifestations of Marfan syndrome (MFS) is unknown in Korean MFS patients.
