Platform with modular attachments that can improve initial fixation, fracture reconstruction, and joint biomechanics RTSA joints and prostheses

摘要

In some embodiments, the present invention is directed to a retrograde shoulder joint and prosthesis that supports attachment of a plurality of different types of modular attachments: 1) to improve joint and implant fixation in the case of severe bone loss / fracture (i. E. 2) provide joint line lateralization to improve tissue stability in the case of severe joint and / or scapular bone loss, and 3) provide a significant Can facilitate the use and containment of joints and bone implants in cases of joint / scapula bone loss, especially where joints and defects are unacceptable and / or localized; and 4) cancellous bone fractures, joints and fractures, and / In the case of the at the same time, joints and fixation can be achieved while reconstructing the scapula, and 5) to improve muscle tension and also to the lateral side of each muscle Rotational and abduction moments To improve arm length, improved rTSA joint biomechanics, especially posterior rotator cuff efficiency (RTSA), by modifying the lines of infraspinatus muscle and teres minor muscle, posterior rotator cuff efficiency), which can be used to provide posterior rotator cuff efficiency.
