Rotator cuff tear; Other names: Rotator cuff injury, rotator cuff disease: Some of the muscles of the rotator cuff, with a tear in the supraspinatus muscle: Specialty: Orthopedics: Symptoms: Shoulder pain, weakness [1] Types: Partial, complete [2] Diagnostic method: Based on symptoms, examination, medical imaging [2] Differential diagnosis
A torn rotator cuff can occur following trauma to the shoulder or it can occur through the "wear and tear" on tendons, most commonly the supraspinatus tendon found under the acromion. Rotator cuff injuries are commonly associated with motions that require repeated overhead motions or forceful pulling motions.
The recovery depends upon many factors, including where the tear was located, how severe it was, and how good the surgical repair was. [ citation needed ] It is believed that it takes at least four to six weeks for the labrum to re-attach itself to the scapula bone (shoulder blade), and probably another four to six weeks to get strong.
MRI showing subacromial impingement with partial rupture of the supraspinatus tendon, but no retraction or fatty degeneration of the supraspinatus muscle. Impingement syndrome can be diagnosed by a targeted medical history and physical examination , [ 11 ] [ 12 ] but it has also been argued that at least medical imaging [ 13 ] (generally X-ray ...
Besides not wanting to risk the usual risks of surgery such as infection, shoulder replacement can lead to a variety of complications including rotator cuff tear and glenohumeral instability. However, despite these risks, shoulder replacement shows promise with a low rate of complication which depending on the type of surgery is close to 5%. [20]
The supraspinatus muscle performs abduction of the arm, and pulls the head of the humerus medially towards the glenoid cavity. [5] It independently prevents the head of the humerus from slipping inferiorly. [5] The supraspinatus works in cooperation with the deltoid muscle to perform abduction, including when the arm is in an adducted position. [5]
