The application discloses an artificial acetabular cup and a manufacturing method thereof. The artificial acetabular cup has an annular base and a dome extending from the annular base. At least a part of the inner layer of the dome is a solid layer, at least a part of the outer layer of the dome is a porous structure layer, and the thickness of the inner layer is less than that of the porous structure layer. The artificial acetabular cup of the present application has lower production cost and better performance.

Prostheses, acetabular apparatuses, and methods of use are disclosed. In some embodiments, an acetabular apparatus includes an acetabular cup and an acetabular cage disposed within an interior of the acetabular cup. The acetabular cage may include a central portion including a first section and a second section rotatably coupled together, and a first flange extending from the first section and a second flange extending from the second section. The acetabular prosthesis may further include a fastener extending through each of the acetabular cup and the central portion of the acetabular cage.

In the present disclosure, an artificial joint shell includes a base and a coating film. The base has a cup shape and includes an outer surface including a first region and a second region adjacent to the first region. The coating film contains a calcium phosphate-based material and an antimicrobial material and is disposed across the first region and the second region of the outer surface of the base. A surface of the coating film in the first region has a larger surface roughness than a surface of the coating film in the second region.

An acetabular hip implant includes a plurality of rings secured to an acetabular shell component. A method of fabricating a customized, patient-specific version of such an implant is also disclosed.

The acetabular cage may include a central portion including a first section and a second section rotatably coupled together, and a first flange extending from the first section and a second flange extending from the second section. The acetabular prosthesis may further include a fastener extending through each of the acetabular cup and the central portion of the acetabular cage.

An implant includes a base, a flange, and ridge. The flange extends from the base. The ridge extends from the flange. A hole extends through the flange and the ridge. A system with the implant includes a fastener extending through the ridge of the implant. The implant is placed into bone by securing a base of the implant to a main complementary contact surface of bone and by securing a ridge extending outwardly from a flange of the implant to a secondary complementary contact surface of bone spaced from the main complementary contact surface.

A reverse hip prosthesis include an acetabular cup arrangement configured for insertion into an acetabulum of a patient and fixation therein, an acetabular ball configured for threaded attachment to the acetabular cup arrangement, a femoral stem configured for insertion into an intramedullary femoral canal of the patient, and a femoral cup arrangement configured for attachment to the femoral stem and to operatively receive the acetabular ball therein. The acetabular cup arrangement includes an anchor portion which becomes fixed to the patient's acetabulum and is the largest size suitable for the patient, and an insert which comes in different sizes and are connectable to the anchor portion, so that the most appropriate insert for the patient may be used. The acetabular cup arrangement and ball are interconnected with a threaded stem that also functions as an artificial Ligamentum Teres.
