Diagnosis is usually suspected by clinical history and confirmed by MRI, in which edema of the teres minor is seen, with variable involvement of the deltoid.The circumflex humeral artery may also be compressed.
The teres minor (Latin teres meaning 'rounded') is a narrow, elongated muscle of the rotator cuff. The muscle originates from the lateral border and adjacent posterior surface of the corresponding right or left scapula and inserts at both the greater tubercle of the humerus and the posterior surface of the joint capsule.
Teres minor), 15. Biceps muscle. The rotator cuff (SITS muscles) is a group of muscles and their tendons that act to stabilize the human shoulder and allow for its extensive range of motion. Of the seven scapulohumeral muscles, four make up the rotator cuff. The four muscles are: supraspinatus muscle; infraspinatus muscle; teres minor muscle
Symptoms may occur immediately after trauma (acute) or develop over time (chronic). Acute injury is less frequent than chronic disease, but may follow bouts of forcefully raising the arm against resistance, as occurs in weightlifting, for example. [29] In addition, falling forcefully on the shoulder can cause acute symptoms.
The onset of the pain may be acute if due to an injury or insidious if due to a gradual process such as an osteoarthritic spur. The pain has been described as dull rather than sharp, and lingers for long periods of time, making it hard to fall asleep. [2] Other symptoms can include a grinding or popping sensation during movement of the shoulder ...
An injury to the axillary nerve normally occurs from a direct impact of some sort to the outer arm, though it can result from injuring a shoulder via dislocation or compression of the nerve. The axillary nerve comes from the posterior cord of the brachial plexus at the coracoid process and provides the motor function to the deltoid and teres ...
An example of injury to the axillary nerve includes axillary nerve palsy. Injury to the nerve results in: Paralysis of the teres minor muscle and deltoid muscle, resulting in loss of abduction of arm (from 15-90 degrees), weak flexion, extension, and rotation of shoulder. Paralysis of deltoid and teres minor muscles results in flat shoulder ...
Symptoms of axillary nerve compression include axillary nerve related weakness of the deltoid muscle (shoulder abduction) and teres minor (external rotation of the arm) as well as numbness of the lateral shoulder. The quadrangular space is the most common site of axillary nerve compression.
