The purpose of this project is to provide information which can help us understand what happens over time to rotator cuff tears. In this study, the investigators will follow a population of people with rotator cuff tears that do not hurt (asymptomatic) and to establish the probability that an asymptomatic rotator cuff tear, identified in the context of contralateral symptoms, will become symptomatic over time. To determine with ultrasound the probability that a rotator cuff tear will enlarge over time. To determine if symptom progression correlates with enlargement of the rotator cuff tear and/or degenerative changes on radiographs. In order to obtain data, study subjects will be recalled for follow-up at 1 year time points over a 5 year period. The study subjects will have repeat physical exam, ultrasound and radiographic examinations. A control group of normal patients will also be followed for comparison.
The specific aims of our study are:
1. To determine the probability that an asymptomatic rotator cuff tear will become symptomatic over time.
2. To determine which epidemiological factors correlate with symptomatic progression.
3. To determine if symptomatic progression correlates with enlargement of the rotator cuff tear as determined at sonography.
4. To determine the value of routine sonographic scanning of the asymptomatic shoulder.

There are two ways in which surgeons repair rotator cuff tears. An open method involves making an incision (cut) 5-6 inches in length in the skin and repairing the tear with the skin open,...
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...
The cycloergometer is a mechanical device consisting of a bicycle frame fixed on a support base, designed to measure the amount of muscle work performed during exercise and the resistance ...
Degenerative partial and complete rupture of the rotator cuff is a common injury among elder patients. However, the clinical manifestation varies largely with some patients having severe p...
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...
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...
The objective of this study was to investigate whether rotator cuff tear morphology could be visualized using radial MRI. We retrospectively investigated 52 shoulders that underwent preoperative MRI a...
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...
A 'terrible triad' of anterior shoulder dislocation, axillary nerve damage and rotator cuff tear has been previously described. However, we are unaware of any report of anterior shoulder dislocation, ...
Rotator cuff muscle atrophy is frequently studied, but it is unknown whether redistribution of mechanical load in the presence of a rotator cuff tear influence muscle atrophy that is observed in patie...
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.
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.

Injuries to the ROTATOR CUFF of the shoulder joint.
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.
The tear-forming and tear-conducting system which includes the lacrimal glands, eyelid margins, conjunctival sac, and the tear drainage system.
Radiology is the branch of medicine that studies imaging of the body; X-ray (basic, angiography, barium swallows), ultrasound, MRI, CT and PET. These imaging techniques can be used to diagnose, but also to treat a range of conditions, by allowing visuali...
