Summary of "The teres minor muscle in rotator cuff tendon tears."

Although the teres minor has received little attention in the literature compared to the other musculotendinous units of the rotator cuff, it is an important component of shoulder function. Our purpose was to study the appearance of the teres minor muscle on CT and MRI images in various patterns of rotator cuff tears. MATERIALS AND
We analyzed the appearance of the teres minor according to the Walch classification (normal, hypertrophic, atrophic, or absent) in 1,332 CT and in 240 MRI images of rotator cuff tears and we correlated it with the type of rotator cuff tears, time period between initial onset of symptoms and diagnostic imaging, age of the patient at the time of imaging, and degree of fatty infiltration of other rotator cuff muscles.
The teres minor was classified as normal in 90.8% of cases, hypertrophic in 5.8%, atrophic in 3.2%, and absent in 0.2%. Significant variability existed in the appearance of the teres minor muscle among different patterns of rotator cuff tears in the CT (P < 0.0001) and MRI groups (P < 0.0001). The teres minor appeared most frequently hypertrophic in anterior tears and atrophic in posterior-superior tears.
The teres minor was normal in most rotator cuff tears. A morphologic classification system allowed the appearance of the teres minor to be defined in isolated and multiple rotator cuff tears in CT and MRI images.

Hypertrophic changes of the teres minor muscle in rotator cuff tears: quantitative evaluation by magnetic resonance imaging.

Few reports have assessed the teres minor (TM) muscle in rotator cuff tears. This study aimed to quantitatively analyze the morphologic changes of the TM muscle in patients with or without rotator cuf...

Reduced muscle fiber force production and disrupted myofibril architecture in patients with chronic rotator cuff tears.

A persistent atrophy of muscle fibers and an accumulation of fat, collectively referred to as fatty degeneration, commonly occur in patients with chronic rotator cuff tears. The etiology of fatty dege...

Dual-camera technique for arthroscopic rotator cuff repair.

An all-arthroscopic rotator cuff repair demands a high level of technical skill and is associated with a steep learning curve. It is well accepted that small rotator cuff tears or partial tears can be...

Comma sign-directed repair of anterosuperior rotator cuff tears.

The comma sign was described as an arthroscopic landmark to identify the torn subscapularis stump to mobilize and repair the tendon in anterosuperior rotator cuff tears. It was hypothesized that it is...

Prevalence of rotator cuff tears in operative proximal humerus fractures.

Proximal humerus fractures and rotator cuff tears have been shown to have increasing rates with advancing age, theoretically leading to significant overlap in the 2 pathologies. The goal of this study...

Medical and Biotech [MESH] Definitions

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. (From Jablonski's Dictionary of Syndromes and Eponymic Diseases, 2d ed)

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.

Surgical procedure by which a tendon is incised at its insertion and placed at an anatomical site distant from the original insertion. The tendon remains attached at the point of origin and takes over the function of a muscle inactivated by trauma or disease.

Inflammation of the synovial lining of a tendon sheath. Causes include trauma, tendon stress, bacterial disease (gonorrhea, tuberculosis), rheumatic disease, and gout. Common sites are the hand, wrist, shoulder capsule, hip capsule, hamstring muscles, and Achilles tendon. The tendon sheaths become inflamed and painful, and accumulate fluid. Joint mobility is usually reduced.

Exercises that stretch the muscle fibers with the aim to increase muscle-tendon FLEXIBILITY, improve RANGE OF MOTION or musculoskeletal function, and prevent injuries. There are various types of stretching techniques including active, passive (relaxed), static, dynamic (gentle), ballistic (forced), isometric, and others.
