Abstract

The invention relates to the technical field of orthopedics and discloses an orthopedic implant. The orthopedic implant is spherical in shape and concave in a region of a bottom surface portion of theorthopedic implant to form an inner concave surface for contacting an acetabular liner or a femoral ball head to form a joint movable friction pair; at least a portion of that bottom region of the external spherical surface of the orthopedic implant extend outwardly to form an extension structure for contacting the human primary bone outside the acetabular fossa aft the orthopedic implant is implanted into the acetabular fossa of the human primary pelvis. In the manner described above, the present invention can improve the biological fixation performance of orthopedic implants.

Description

technical field [0001] The invention relates to the technical field of orthopedics, in particular to an orthopedic implant. Background technique [0002] With the development of medical technology, more and more implants are introduced for the treatment of diseases, such as artificial joint replacement surgery, through the introduction of artificial joints to treat osteoarthritis, aseptic necrosis of the femoral head, traumatic arthritis, Congenital acetabular dysplasia and other diseases. However, the inventors of the present invention have found in the long-term research and development process that the contact area between implants used in orthopedics and human native bone is limited, resulting in poor biological fixation performance of the implants. Contents of the invention [0003] In view of this, the technical problem mainly solved by the present invention is to provide an orthopedic implant capable of improving the biological fixation performance of the orthopedi...
