The rotator cuff is comprised of four muscles: supraspinatus, infraspinatus, teres minor, and subscapularis. The myotendinous tear of the TM was confirmed, as well as the integrity of the IS (Fig. The extremely low frequency of reports in literature highlights the rarity of these lesions, but also perhaps the fact that they might be under diagnosed. Acute teres major and teres minor pain can happen due to a sudden movement like holding a rope during water sports or while throwing a powerful pitch in baseball. Early appropriate imaging was done (magnetic resonance imaging [MRI] and arthro-computed tomography scan); it revealed an isolated tear of the TM at the myotendinous junction. Williams MD, Edwards TB, Walch G. Understanding the Importance of the teres minor for shoulder function:Functional anatomy and pathology. The test is positive if the patient cannot rotate the shoulder externally, indicating minor pathology.[9][10][11]. The consent submitted will only be used for data processing originating from this website. Please note our 24 Hour Cancelation Policy. Wilson L, Sundaram M, Piraino DW, Ilaslan H, Recht MP. Rupture in the teres minor can cause a loss of external rotation, while attributes to severe functional disabilities in being able to participate in regular daily activities. What we want is a neutral position for our shoulders not too far forward and not too far back. The teres minor muscle also assists with shoulder extension and downward rotation. It lies right next to it and has similar attachment points. The teres minor is an elongated, narrow muscle within the rotator cuff of the shoulder. The main causes of teres major and minor pain are: Another reason for the teres major or teres minor pain is the trigger points which result in severe pain in the posterior deltoid and at the top of the triceps brachii muscle. As a rotator cuff muscle, the teres minor stabilizes the ball-and-socket glenohumeral joint by helping hold the humeral head (ball) into the shallow glenoid cavity of the scapula (socket). 4). Teres Major and Minor.

These myotendinous lesions of the IS are known to evolve rapidly (<1 year) toward severe atrophy and fatty infiltration of the muscle, with potential chronic pain and functional impairment [9]. Impingement is caused by narrowing of the space between the acromion and the rotator cuff, often due to repeated overhead activity of thearm that inflames the rotator cuff tendons. This shoulder had never before been injured or painful. In addition, the teres minor plays a very small role in shoulder adduction (bringing arm towards the body).2, An injury to this muscle can be the result of trauma, such as a fall, direct blow to the shoulder, or rapid use of force (like pulling on a starter cable for a lawn mower).

The upper fibers of the muscle culminate in a tendon that insertsonto the greater tubercle of the humerusthe tendon blends into the capsule of the shoulder joint. Doing the stretches regularly can also prevent injuries to teres major and minor. As this muscle supports the infraspinatus you will understand that trigger points or excessive muscle tension in this muscle will affect the same movements. Rest: After an injury, it is important to allow the muscle time to heal. A complete, or. Ice: Applying ice to the affected area can help to reduce swelling and inflammation. The teres minor muscle has a tendon that can be affected by tendinitis, leading to pain and limited range of motion in the shoulder. The most effective treatments for teres minor injuries include rest, ice, compression, and elevation (RICE), non-steroidal anti-inflammatory drugs (NSAIDs), physical therapy, and in severe cases, surgery. Nov-Josserand L, Costa P, Liotard JP, Safar JF, Walch G, Zilber S. Results of latissimus dorsi tendon transfer for irreparable cuff tears. It supports the infraspinatus with the outward/lateral rotation of the shoulder. Patients can get discouraged after months of no improvement if they are not educated prior to surgery that this is normal and expected. Isolated IS myotendinous tears more typically occur in middle-aged patients and after a shoulder injury in only 22% of the cases [9]. Because the muscle also acts to stabilize and compress the humeral head in the glenoid fossa, weakness may also lead to secondary issues, including shoulder impingement.3, 4. Its better to work your mobility to prevent an injury, than wait until you need to recover from one. Physiopedia articles are best used to find the original sources of information (see the references list at the bottom of the article). In this article, we described the first reported case of an isolated myotendinous TM tear. It becomes then solely responsible for active external rotation and essential to maintain shoulder balance [4, 5]. http://creativecommons.org/licenses/by-nc-nd/4.0/ [2] It's sometimes called "lat's little helper" because of its synergistic action with the latissimus dorsi.

It travels caudally beforedividing into two arteries: the circumflex scapular and the thoracodorsal. Melis B, DeFranco MJ, Ldermann A, Barthelemy R, Walch G. The teres minor muscle in rotator cuff tendon tears. There are several exercises that one can do to reduce teres major or teres minor pain. The functional and anatomical results in this patient were excellent at the 6-month follow-up point and were maintained overtime, which was comparable to the results published by Zaman and Syed [7] after treating a TM tendon avulsion. Careers, Unable to load your collection due to an error. Finally, Thera-band (T-band) Rows are a great postural training exercise that can be done almost anywhere.

Due to prolonged and regular use of arm and shoulder muscles some people are prone to teres major and teres minor injuries that can be quiet painful. The teres minor is located at the back of the shoulder, around the arm pit. In some instances, part or whole of the muscle fibers are affected, while in severe cases the tendons attached with the muscle also .

It is one of several muscles that make up the rotator cuff, a group of muscles and tendons that surround the shoulder joint and help to stabilize and move the shoulder. The teres minor also laterally or externally rotates the arm at the shoulder joint. The rehabilitation protocol included physiotherapy for analgesic purposes, recovery of passive and active range of motion, followed by overall muscle reinforcement, and specific reinforcement of the teres major muscle in eccentric mode.

Literal meaning Lesser round or rounded off. Teres minor innervation in the context of isolated muscle atrophy. To date, an isolated myotendinous rupture of the TM, without any lesion of the other cuff tendons, has never been reported in literature.

I know how hard that all was, and I want to save you from heading down that same path. The patient was immobilized for 1 month in neutral rotation and then was allowed to begin the rehabilitation process. First, the axillary nerve is posterior to the axillary artery and anterior to the subscapularis muscle, then it travels to the inferioredge of the subscapularis muscle. Trigger points in the teres minor can trigger pain right at their location, but also refer pain to other, more distant parts of the body. Based on this data, and considering the young age and the functional demand of our patient, repairing this lesion in the acute phase seemed to be justified. This can be achieved through a combination of stretching and strengthening exercises. cookies to help us improve it. The teres major is one of four rotator cuff muscles that is involved in many shoulder pathologies, including quadrangular space syndrome[10].
