Background
Hip Arthroplasty is one of the most common procedures performed for the treatment of osteoarthritis,
but it can be done for other reasons such as fracture,
dysplasia,
inflammatory arthritis and osteonecrosis.
This is a successful orthopaedic procedure,
since it allows pain relief,
restoration of function and improved quality of life.
Hip arthroplasty is divided in two categories: hemiarthroplasty,
when the acetabulum is spared,
and total arthroplasty,
when both the femoral head and the acetabulum are replaced.
Both can be cemented or noncemented.
The postoperative radiography is obtained to assess the position of the prosthesis’ components and is used as a reference image for future comparisons.
There are multiple causes of arthroplasty failure,
including periprosthetic lucencies,
sclerosis and bone proliferation and component failure or fracture.
It’s important to recognize the signs of an arthroplasty complication in order to prolong the life of the prosthesis and prevent the need for a surgical revision.
