Reverse total shoulder arthroplasty is indicated for the treatment of conditions that cannot be treated with conventional arthroplasty or other procedures. These primarily include degenerative and incapacitating conditions with irreparable rotator cuff and loss of the normal biomechanical coupling of the shoulder.
Reverse total shoulder arthroplasty is used to restore our mobility in patients with severe disability from rotator cuff pathology and associated arthritis in conventional shoulder arthroplasty. The metal ball of the prosthesis is attached to the humerus or upper arm, and the socket is attached to the G glenoid or shoulder blade. In contrast, in reverse total shoulder arthroplasty, the plastic socket is fastened to the arm and Theos sphere is implanted on the G glenoid to implant a reverse shoulder prosthesis following anesthesia and retraction of the overlying muscle.
The humerus or upper arm bone is exposed and the humeral head is reamed following exposure and reaming of the G glenoid. The G glenoid base plate and g Glens sphere are inserted and screwed into place. The next step is to cement the humeral component in place.
