Effectiveness of Treatments for Massive Rotator Cuff Tears: Mixed Methodology.

The rehabilitation is based on restoring the balance of the shoulder joint. Aiming to diminish pain and restore function, pain control and inflammation are addressed during the firsts 3-6 weeks. Before week 3, pendulum movements are allowed to initiate mobilization of the shoulder joint. Aiming to gain (almost) complete shoulder joint mobility, a passive and active mobility exercise program is carried out. Lastly, the focus is on muscle reinforcement, performing a series of active exercises with weights or bands to exercise different muscles of the shoulder or the shoulder girdle.

Arthroscopic decompression surgery of the rotator cuff tear consists of cleaning the subacromial space. The procedures that are sometimes performed to diminish pain may include, removing the inflamed bursa, releasing the long head of the biceps (if injured), or lightly burring the acromion bone under which the tendons slide.

The reverse prosthesis consists of shoulder articular joint replacement. The humeral head is sectioned, and, on the scapular side, a metal tray is placed, which is fixed with screws, and a metal half-sphere fixed to the metal tray. On the humeral side, a metal stem with a concave plastic component is placed to articulate with the metal half-sphere, allowing shoulder mobility without the need of rotator cuff muscles.

In the reverse prosthesis procedure and arthroscopic decompression surgery, the pain-relief medication plan is a standard regimen for all patients, which can be modified as needed. This plan is based on 50mg of dexketoprofeno, 1g of paracetamol, and 100mg of tramadol.

In the reverse prosthesis procedure, a Delta III reverse shoulder prosthesis is applied. The original design was developed by Grammont in 1980's, and has 2 components: 1) a metal tray fixed with screws, and a metal half-sphere fixed to the metal tray, and 2) a concave polyethylene component.
