Rotator cuff tears are one of the primary causes of shoulder pain and dysfunction in the upper extremity accounting over 4.5 million physician visits per year with 250,000 rotator cuff repairs being performed annually in the United States. While the tear is often considered an injury to a specific tendon/tendons and consequently treated as such, there are secondary effects of rotator cuff tears that may have significant consequences for shoulder function. Specifically, rotator cuff tears have been shown to affect the joint cartilage, bone, the ligaments, as well as the remaining intact tendons of the shoulder joint. Injuries associated with the upper extremities account for the largest percent of workplace injuries. Unfortunately, the variable success rate related to rotator cuff tears motivates the need for a better understanding of the biomechanical consequences associated with the shoulder injuries. Understanding the timing of the injury and the secondary anatomic consequences that are likely to have occurred are also of great importance in treatment planning because the approach to the treatment algorithm is influenced by the functional and anatomic state of the rotator cuff and the shoulder complex in general. In this review, we summarized the contribution of rotator cuff tears to joint stability in terms of both primary (injured tendon) and secondary (remaining tissues) consequences including anatomic changes in the tissues surrounding the affected tendon/tendons.

Due to the highly organized tissue and avascular nature of the rotator cuff, rotator cuff tears have limited ability to heal after the tendon is reinserted directly on the greater tubercle of the hume...
Rotator cuff tears in older individuals may result in decreased muscle forces and changes to force distribution across the glenohumeral joint. Reduced muscle forces may impact functional task performa...
Shoulder instability and rotator cuff pathology can provide a challenging problem, especially in the revision setting. Allograft use in primary or revision surgical intervention for shoulder instabili...
Certain metabolic factors have been proposed as risk factors for a posterosuperior rotator cuff tear. Although metabolic syndrome is of increasing concern in industrialized societies, little informati...
Failed rotator cuff repairs can pose a clinical challenge to the treating orthopedic surgeon. There are many nonsurgical and surgical options available to address the failed rotator cuff repair. Surgi...
Randomized clinical study involving 44 patients, evaluating the effect of mesenchymal cells on rotator cuff repair. The primary outcome will be post-operative MRI tendon integrity and seco...
The purpose of this study is to examine deficits in activation and motor patterns, as well as central drive in patients with rotator cuff tendinopathy. There are three specific aims: (1) d...
This trial is to evaluate the effectiveness of the ArthroFLEX® ECM scaffold graph as an augment in rotator cuff repair surgery to reduce the failure rate of rotator cuff repairs for large...
Retear rates after arthroscopic rotator cuff repairs remain unsatisfactorily high. Recently, attention has been paid to restore the rotator cuff's native anatomy by reconstructing the supe...
The purpose of this study is to determine whether the immobilization period is helpful for the better healing of repaired rotator cuff. The investigators hypothesis is that the longer imm...
Rapidly destructive shoulder joint and bone disease found mainly in elderly, and predominantly in women. It is characterized by SHOULDER PAIN; JOINT INSTABILITY; and the presence of crystalline CALCIUM PHOSPHATES in the SYNOVIAL FLUID. It is associated with ROTATOR CUFF INJURIES.
Injuries to the ROTATOR CUFF of the shoulder joint.
Compression of the rotator cuff tendons and subacromial bursa between the humeral head and structures that make up the coracoacromial arch and the humeral tuberosities. This condition is associated with subacromial bursitis and rotator cuff (largely supraspinatus) and bicipital tendon inflammation, with or without degenerative changes in the tendon. Pain that is most severe when the arm is abducted in an arc between 40 and 120 degrees, sometimes associated with tears in the rotator cuff, is the chief symptom.

The musculotendinous sheath formed by the supraspinatus, infraspinatus, subscapularis, and teres minor muscles. These help stabilize the head of the HUMERUS in the glenoid fossa and allow for rotation of the SHOULDER JOINT about its longitudinal axis.
Conditions which feature clinical manifestations resembling primary Parkinson disease that are caused by a known or suspected condition. Examples include parkinsonism caused by vascular injury, drugs, trauma, toxin exposure, neoplasms, infections and degenerative or hereditary conditions. Clinical features may include bradykinesia, rigidity, parkinsonian gait, and masked facies. In general, tremor is less prominent in secondary parkinsonism than in the primary form.

A joint is where two or more bones come together, like the knee, hip, elbow, or shoulder. Joints can be damaged by many types of injuries or diseases, including Arthritis - inflammation of a joint causes pain, stiffness, and swelling with ...
Pain is a feeling (sharp or dull) triggered in the nervous system which can be transient or constant. Pain can be specific to one area of the body eg back, abdomen or chest or more general all over the body eg muscles ache from the flu. Without pain ...
