Mild supraspinatus and infraspinatus tendinosis refers to a degenerative condition affecting the tendons of the supraspinatus and infraspinatus muscles, which are part of the rotator cuff in the shoulder. This condition is characterized by changes in the tendon tissue, often due to repetitive strain or overuse, leading to pain and reduced function. "Mild" indicates that the changes are not severe, suggesting early-stage degeneration. Treatment typically involves rest, physical therapy, and possibly anti-inflammatory medications to alleviate symptoms and improve shoulder function.

What is Mild to moderate supraspinatus tendinosis?
Mild to moderate supraspinatus tendinosis is a condition characterized by inflammation or degeneration of the supraspinatus tendon in the shoulder. It can cause pain, weakness, and limited range of motion in the affected shoulder. Treatment typically involves rest, physical therapy, and sometimes corticosteroid injections.
What muscles form the rotator cuff?
subscapularis, supraspinatus, infraspinatus and teres minor
What does it mean to have ventral supraspinatus tendinosis?
Ventral supraspinatus tendinosis refers to degeneration of the supraspinatus tendon on the front or ventral side of the shoulder. This condition can cause pain, weakness, and limited range of motion in the shoulder. Treatment may include rest, physical therapy, and in some cases, surgery.
Is the subscapular fossa located anterior or posterior to the supraspinatus and infraspinarus fossae?
The subscapular fossa is located anterior to the supraspinatus and infraspinatus fossae on the scapula.
What are the muscles that contribute to the rotator cuff?
1- Supraspinatus and its function is to abduct the arm ,and it's innervated by the Suprascapular nerve. 2- Infraspinatus muscle and its function is to externally rotate the arm ,and it's innervated by the Suprascapular nerve. 3- Teres minor muscle and its function is to externally rotate the arm ,and it's innervated by the Axillary nerve. 4- Subscapularis muscle and its function is to internally rotate the humerus ,and it's innervated by the Upper and Lower subscapular nerve.
How many muscles make up the rotator cuff?
4, supraspinatus, infraspinatus, teres minor and subscapularis.
What is the antagonist of rhomboid muscle?
There are more than one: The deltoid, supraspinatus, infraspinatus, teres major and minor and the subscapularis.
What type of fibers are present in supraspinatus and infraspinatus muscles?
The supraspinatus muscle contains mostly type I (slow-twitch) muscle fibers, which are more fatigue-resistant and used for sustained contractions. The infraspinatus muscle contains a mix of type I and type II (fast-twitch) muscle fibers, which are used for more powerful and quick contractions.
What muscles are involved in lateral rotation of the humerus?
The rotator cuff muscles: Supraspinatus Infraspinatus Teres Minor Supscapularis Easily remembered as SITS.
The rotator cuff of the shoulder is composed mainly of what?
There are four tendons in the rotator cuff, and these tendons are attached individually to the following muscles: teres minor, subscapularis, infraspinatus, and the supraspinatus.
What muscles does one use when one shrugs?
By doing shrugs, with or without weights, one uses many muscles. Shrugging uses the teres minor, supraspinatus, infraspinatus, subscapularis, the delta and traps.
What muscle in the body initiate abduction of the arm?
The main abductors of the arm are the supraspinatus and deltoids. Rotation can be internal or external. The main internal rotators are the subscapularis and teres major. The main external rotators are the infraspinatus and teres minor.
