Teres Minor
This is the technical name of the muscle being described.  This name may be used to find additional information in any medical resource. Teres Minor
A group of muscles generally denotes muscles of the same function and may share a common attachment point. Rotator Cuff
Muscle function, in this definition, is what the muscle could do if it was to contract by itself with the body in anatomical position.  This is a general definition of muscle function.  For more information on how muscles work together on the body please refer to a physiology or functional anatomy text.

All of the muscles of the rotator cuff function to stabilize the glenohumeral (g/h) joint, which is another name for the shoulder.  The teres minor also laterally rotates the arm at the shoulder.

A description of where a Myofascial Trigger Point may produce pain in the body.  This area is generally located away from the trigger point.

Pain from the teres minor refers to the posterior deltoid area but is usually characterized by a painful, “prune-sized” area that seems to be deep in the posterior deltoid muscle.

A description of the symptoms a person may experience with trigger points in the muscle being described.

People who have TrPs in this muscle complain of posterior shoulder pain rather than restricted motion.  Numbness or tingling that is aggravated by shoulder activity above shoulder level or behind the back may be felt in the fourth and fifth fingers when there are TrPs in the teres minor alone.  They may also describe a “painful bursa” about the size of a prune that seems to be deep in the posterior deltoid muscle close to the attachment of the teres minor on the humerus.


 A list of possible diseases that fit the information derived from examination of a patient.

  1. Rotator cuff lesions.
  2. Quadrilateral space syndrome.
  3. Ulnar neuropathy.
  4. C8 radiculopathy.
  5. Subdeltoid bursitis.
  6. Acromioclavicular separation.

A list of activities or positions that may either CAUSE a trigger point to manifest or PROLONG a pain condition respectively.

It is important to understand that the teres minor is usually not involved as a single muscle syndrome.

    1. Overload stresses (like reaching up or out and behind the shoulder).
    2. Motor vehicle accidents.
    3. Loss of balance while lifting a heavy object overhead.
    4. Working in cramped quarters with the arm reaching overhead.
    5. Playing volleyball.

A corrective action is usually a modification of daily routine which will reduce stress on the affected muscle(s) in a person with myofascial trigger points.

  1. Avoid excessive or repetitive load on the muscle.
  2. Position the arm correctly to avoid full shortening during sleep.
