What causes hip Protrusio?
Protrusio can develop in association with metabolic bone diseases such as osteogenesis imperfecta, Marfan’s Syndrome, and Paget’s disease, inflammatory arthritis or osteoarthritis, tumors, or result from prior trauma.
What causes bilateral protrusio acetabuli?
Bilateral condition could be found in conditions such as rheumatoid arthritis, Paget’s disease, ankylosing spondylitis, Marfan’s syndrome and osteomalacia. The joint replacement surgery is usually necessary in cases of severe pain or substantial joint restriction owing to secondary hip arthritis.
What is protrusio acetabuli hip?
Protrusio acetabuli is a condition of the hip where there is medial displacement of the femoral head into the pelvis and the medial aspect of the femoral head lies medial to the ilioischial line.1 Protrusio acetabuli could be primary or secondary.
How is protrusio acetabuli detected?
Protrusio acetabuli is identified on anteroposterior (AP) radiographs of the pelvis with an acetabular line projecting medial to the ilioischial line.
What is Protrusio deformity?
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.
How is acetabular Protrusio treated?
Total hip arthroplasty is the recommended treatment for the older adult with protrusio acetabuli and degenerative changes.
Is Protrusio Acetabuli rare?
Protrusio acetabuli (arthrokatadysis or Otto pelvis) is a relatively rare condition associated with secondary osteoarthritis of the hip.
Is acetabular Protrusio painful?
Protrusio acetabuli is a rare pathologic morphology of the hip in which the femoral head protrudes into the true pelvis [48]. It is a reported cause of hip pain and osteoarthritis in young adults [21].
How common is acetabular Protrusio?
What is protrusio acetabuli?
Protrusio acetabuli is an uncommon defect of the acetabulum, 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.
What is total hip arthroplasty for protrusio?
Total Hip Arthroplasty in Patients with Protrusio. Acetabular protrusio, which is also known as arthrokatadysis, or the “Otto Pelvis” is a condition more commonly seen in patients with inflammatory arthritis such as lupus, ankylosing spondylitis, and rheumatoid arthritis ( Fig. 75.1 ). It is seen more often bilaterally than in unilateral hips.
What causes protrusio acetabuli in osteomalacia?
Bilateral protrusio acetabuli may be caused by rheumatoid arthritis, Paget’s disease, or osteomalacia. In addition, protrusio acetabuli may be present bilaterally in Paget’s disease, Marfan syndrome, rheumatoid arthritis, ankylosing spondylitis, and osteomalacia ;
What is the pathophysiology of hip anatomy with protrusion?
The distorted hip anatomy with protrusion may be associated with early degenerative joint disease of the hip.
