To review the normal postoperative imaging findings of Hip Arthroplasty. To depict the most common complications of Hip Arthroplasty and their imaging characteristics.

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...

We selected images of plain radiographs that display the normal imaging findings after a hip arthroplasty from the archives of our institution. We also selected radiographs that show the imaging findings of the most common complications of hip arthroplasty. NORMAL POSTOPERATIVE FINDINGS The initial posteroperative radiography must be acquired in a standard way since sequential radiography is the most valuable method for detecting complications. The recommended initial posteroperative radiography is a standing anteroposterior pelvic radiograph, with the hips in internal rotation and extension. The centre...

As a result of an aging population and longer life expectancy, hip arthroplasty is becoming a procedure even more frequent and needed. Conventional radiography remains one of the most important imaging techniques in assessing hip arthroplasty since it is available at a low cost with no artefact. It is important for the radiologist to be familiar with the normal findings of hip arthroplasty and to be able to recognize abnormal situations.
