Idiopathic frozen shoulder is defined as a self-limiting regional skeletal problem whose etiology remains unknown. It begins insidiously, without a regarded trigger. Clinically, patients initially experience or sufferers a phase of pain, followed by a thawing phase in which pain gradually subsides and most of the lost movements returns 1. Clinical diagnosis in the early phase of idiopathic frozen shoulder can be difficult. In the pain phase indications are much like to rotator cuff tendonitis. In the freezing phase the patient often compensates for decreased glenohumeral motion by increased scapulothoracic motion, covering the restrictions in movement. Codman first introduced the term frozen shoulder in 1934 and described that it as a situation which can be difficult to define, difficult to treat and also difficult to explain the point of view of pathology of frozen shoulder. Frozen Shoulder is also named as adhesive capsulitis, periarthritis and pericapsulitis 2. Frozen shoulder, or adhesive capsulitis, was also defined by Reeves in 1975, as a condition of uncertain etiology characterized with the aid of …show more content…
This freedom results from the laxity of its joint capsule and the large size of the humeral head compared with the small size of glenoid cavity. The joint permits movement around three axes and allow flexion-extension, abduction-adduction, rotation, medial and lateral of the humerus and circumduction. Lateral rotation of humerus increases the range of abduction. When the arm is abducted without rotation, available articular surface is exhausted and the greater tubercle contacts the coracoacromial arch, preventing further abduction. If the arm is then laterally rotated 180 degrees the tubercles are rotated posteriorly and more articular surface becomes available to continue elevation. Circumduction at the joint is an orderly sequence of flexion, abduction, extension and
