Abstract

The invention provides an acetabular prosthesis which comprises a cup body and a through hole formed in the top of the cup body. The bottom face of the cup body comprises a first plane portion, the face where the through hole is located forms a second plane portion, and an included angle a is formed between the first plane portion and the second plane portion. According to the technical scheme, the problem that a large amount of sclerotin needs to be ground away when the acetabular cup is implanted in the prior art is effectively solved.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to an acetabular prosthesis. Background technique [0002] Hip dysplasia is one of the most common causes of hip arthritis in our country. Hip arthritis can cause pain in the hip joint, limited mobility and, in severe cases, loss of productivity. Patients with hip dysplasia in childhood can be treated by plaster fixation, muscle release, osteotomy and other methods. However, there are still a large number of patients who still have mild acetabular insufficient coverage after systemic treatment. The angle between the centerline and the edge of the acetabulum is less than or equal to 20 degrees. For such patients in adulthood, the traditional treatment for residual deformity is acetabular osteotomy, or conservative treatment first, followed by total hip replacement after arthritis develops. [0003] The typical anatomy of the acetabular side in dysplasia of the hip is a sha...
