Embodiment Construction

[0052] The present invention will be further described in detail through the drawings and examples below. Through these descriptions, the features and advantages of the present invention will become more apparent.

[0053] The word "exemplary" is used exclusively herein to mean "serving as an example, embodiment, or illustration." Any embodiment described herein as "exemplary" is not necessarily to be construed as superior or better than other embodiments. While various aspects of the embodiments are shown in drawings, the drawings are not necessarily drawn to scale unless specifically indicated.

[0054] Severe wrist trauma, carpal comminuted fracture, malunion, rheumatoid arthritis involving wrist joint destruction, unexplained carpal osteonecrosis and wrist tumors have become common diseases in specialist clinics, and are likely to cause joint pain in patients. The deformity, pain and dysfunction seriously affect their quality of life and bring great pain. For this reason...

Abstract

The invention discloses combined type semi-limited multi-pole artificial wrist joints which can also be called semi-limited double-pole artificial wrist joints. According to the specific pathologicalconditions of damage to wrist joint bones, different assembling and matching manners can be selected, for example, if the pathological conditions show that palm carpus joint surfaces are complete andsclerotin is still good, most of distal row carpi (with small multi-angle bones and capitate bones) can be retained, but if proximal row carpi (navicular bones and lunate bones) and wrist radius jointsurfaces are broken, model selection assembly of proximal row carpectomy excision can be performed; and the artificial wrist joints can also adopt another assembling and matching manner, called semi-limited multi-pole artificial wrist joints, double-row carpi on carpi which are pathologically destroyed can be excised, mutual-matched assembly of palm joints, wrist joints and radius joints can be formed, and flexible, convenient and ideal surgical results can be brought for a person subjected to a surgery.

Description

technical field [0001] The invention relates to a medical professional artificial joint prosthesis, in particular to a combined semi-limited multi-pole artificial wrist joint in the field of hand surgery. Background technique [0002] At present, the use of artificial joint replacement surgery to treat and repair the broken ring of human joints is one of the effective methods agreed by the international medical community. Especially in recent years, with the continuous development of medical technology, the emergence of new biomaterials, and the rapid development of high-tech, replacement and repair of human joint damage and dysfunction have achieved obvious and good clinical results. The application of human hip and knee arthroplasty has been widely promoted and used by doctors in my country, and the satisfactory clinical effect has made it accepted by the majority of patients. [0003] The demand for small and micro joint prostheses in the human body is in urgent need of ...
