Shoulder joint implant

Abstract

The invention discloses a shoulder joint implant for maintaining and properly increasing the distance between a humeral head and an acromion and increasing the distance between a humerus greater tubercle and the acromion at shoulder abduction. The shoulder joint implant comprising a solid cover is characterized in that the solid cover disposed between the end portion of the humerus and the acromion is fixedly connected with the end portion of the humerus; the solid cover is provided with a first surface and a second surface, wherein the first surface fits the end portion of the humerus, and the second surface is disposed with the back to the end portion of the humerus; the second surface directly or indirectly abuts the lower surface of the acromion. With the end portion of the humerus fixedly connected with the solid cover and the solid cover capable of maintaining the distance between the end portion of the humerus and the lower surface of the acromion, the shoulder joint implant hasthe advantages of preventing the pain caused by the impact between the acromion and the end portion of the humerus, restoring normal biomechanical properties of the shoulder joint of a patient, effectively reducing extrusion on surrounding tissues due to the fact that the solid cover is a solid structure and the shape is small when pressed by force, and reducing shoulder discomfort.

Description

technical field

[0001] The invention relates to the medical field, in particular to a shoulder joint implant. Background technique

[0002] Rotator cuff tear is a common cause of shoulder pain, limited mobility and dysfunction. Rotator cuff tear leads to a series of shoulder inflammation and affects the quality of daily life, such as shoulder pain, and caused by shoulder pain Can't sleep at night, can't comb hair, and female patients can't take off their bras, etc. There are a series of surgical methods for its treatment plan, such as muscle tendon transplantation, upper joint capsule reconstruction or reverse shoulder replacement surgery, etc. However, muscle tendon transplantation will destroy the normal structure and destroy anatomy; reverse shoulder replacement is expensive and technically difficult Popularity; while the scientific evidence for upper joint capsule reconstruction needs to be strengthened.
