No, frozen shoulder and dislocated shoulder are not the same thing. They are two different conditions that affect the shoulder joint, but they have distinct causes and symptoms. Frozen shoulder, also known as adhesive capsulitis, is a condition characterized by stiffness and pain in the shoulder joint. It occurs when the connective tissues surrounding the shoulder joint become thickened and tight, limiting the range of motion. The exact cause of frozen shoulder is not fully understood, but it can develop after an injury or surgery, or it may occur spontaneously without any obvious cause. The symptoms of frozen shoulder typically progress through three stages: freezing, frozen, and thawing. On the other hand, a dislocated shoulder happens when the upper arm bone (humerus) comes out of its normal position within the shoulder joint. This displacement can occur due to a sudden trauma or injury, such as a fall, sports-related accident, or a direct blow to the shoulder. Dislocated shoulder often causes intense pain, swelling, and visible deformity of the shoulder. It may also restrict the movement of the affected arm and require medical intervention to put the joint back into its proper alignment.
