Embodiment Construction

[0027] The preferred embodiments of the present invention will be described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described here are only used to illustrate and explain the present invention, and are not intended to limit the present invention.

[0028] In order to improve the stability of prosthesis implantation and enable it to grow into the prosthesis, according to Figure 1-Figure 5 As shown, the present invention provides a prosthesis that retains the bone quality of the greater and lesser trochanters. The main structure includes: a femoral cone 1 connected in sequence, a femoral neck 2, a shoulder 3, and an anti-rotation part 4. The femoral cone 1 is used for Cooperating with the taper of the femoral ball head, the anti-rotation part 4 is used for connecting with the osteotomy segment.

[0029] The technical solution of this embodiment is achieved in the following way: firstly connect the femoral cone ...

Abstract

The invention provides a prosthesis retaining sclerotin of greater and lesser trochanters. The prosthesis comprises a femur cone, a femur neck, a shoulder part and an anti-rotation part which are connected in sequence, the femur cone is used for being in taper fit with a femur ball head, and the anti-rotation part is used for being connected with an osteotomy section. The prosthesis has the advantages that the sclerotin of the greater and lesser trochanters can be effectively reserved, the stability of prosthesis implantation is enhanced, the structure is light in weight, and the postoperative experience of a patient is enhanced.

Description

technical field [0001] The invention relates to the field of medical technology, in particular to a prosthesis for retaining the bones of the greater and lesser trochanters. Background technique [0002] For bone defects caused by comminuted fractures, bone tumors, osteolysis and bone resorption after artificial joint surgery, amputation was often used before the 1990s. Nowadays, the upper femoral hip joint prosthesis is generally used, but due to its structural characteristics, the soft tissue at the position of the greater and lesser trochanters needs to be combined with the prosthesis through binding, and cannot grow into the prosthesis, and its weight is easy to burden the patient , the stability of implantation is also poor. Contents of the invention [0003] The present invention provides a prosthesis that retains the bone of the greater and lesser trochanters, with the purpose of overcoming at least one of the above-mentioned technical defects, so that the original...
