What is Protruzyo Acetabuli (Otto Pelvis)?
Protrusio acetabuli, together with the deformity of the medial wall of the acetabulum, is a disease that causes the progressive migration of the femur head into the pelvic cavity, causing some mechanical disorders, pain and limitation of hip movements.
What are the Causes of Protruzyo Acetabuli (Otto Pelvis)?
It can be congenital or may develop due to rheumatoid arthritis, ankylosing spondylitis, osteoarthritis, chronic renal osteodysrophy, rickets, osteoporosis, Paget’s disease, neoplasia, surgical sequelae, traumas and infections.
How to Diagnose Protruzyo Acetabuli (Otto Pelvis)?
Your physician diagnoses hip pain with a history and physical examination. Physical examination manoeuvres, such as rotating the hip in and out, can be used to detect positions that exacerbate pain. It can use imaging studies, including X-rays, CT scans and MRI scans, to further identify the causes of hip pain.
How to Treat Protruzyo Acetabuli (Otto Pelvis)?
The aim of the kaça prosthesis applied in these patients is to eliminate significant mobility limitation with severe pain, strengthen the inner wall of the hip nest and restore the hip rotation center.
It is often preferred to place the prosthesis or apply cemented prosthesis by grafting the resulting femur head graft.
