ruptura_manguito_rotadorThe rotator cuff is a common tendon formed by the four muscles that surround the shoulder joint. The rotator cuff is responsible for joint rotation, captures the humeral head in the concavity of the scapula (glenoid cavity), to allow limb elevation, and contributes to shoulder stability to prevent joint dislocation.

Rotator cuff tears may occur as a result of trauma (falls) or sudden contraction of one of the rotators. They may also occur due to attrition rupture as a consequence of chronic tendon surface abrasion.

Arthroscopic surgical repair is highly effective to relieve pain relief as well as to improve the function of the shoulder joint. In this procedure, the torn portion of the cuff is sutured or reinserted into the bone, depending on the type of tear. Special screws with non-absorbable threads are used to firmly close the ruptured tendons with the humeral bonehead.

There are different types of tendon ruptures and their frequency will make surgery to be simple or complex. After surgery, there is an immobilization period and then physical rehabilitation is started to regain movement and the normal function of the shoulder. The success of the procedure depends on both, the size of the tear and the time between the tear and the beginning of the treatment.
