Adhesive Capsulitis

Adhesive capsulitis: A shoulder condition also known as a frozen shoulder in which the capsule of the shoulder, surrounding the shoulder joint, becomes inflamed and stiff. This results in pain and greatly restricted range of motion.
 

   

Axillary Nerve Injury

Axillary nerve injury: The axillary nerve is an important shoulder nerve as it innervates several shoulder muscles. These muscles include the deltoid muscle, the teres minor rotator cuff muscle and part of the triceps muscle. Damage or injury to the nerve results in reduced or even failed function of these muscles.
 
 
   

Biceps Tendon Dislocation

Biceps tendon dislocation: There are two tendons of the biceps muscle; one of the tendons is attached to the shoulder blade cavity and runs through the shoulder joint through a specific groove or sulcus on the front side of the head of the upper arm bone. The tendon is dislocated when it is displaced from its sulcus.
