Frozen shoulder, as the name suggests, is the stiffness and loss of motion of the shoulder joint. The main source of the condition is pain, and it develops as the patient guards the shoulder joint, leading to stiffness.
It is more common in women. Risk factors include: prolonged immobility after surgery or fracture, diabetes, thyroid diseases, cardiovascular diseases, and Parkinson's disease.
If left untreated, it can resolve over a long period of about 2 years, but range of motion limitations may not completely disappear. Closed manipulation is a method that yields very good results in many resistant cases.
