Adhesive capsulitis or "frozen shoulder" is defined as the progressive development of joint limitation ("stiffness"), both active and passive, and of shoulder pain with no other explanation. The term "peri-arthritis" is confusing and tends to be abandoned. It is a diagnosis of exclusion made on an essentially clinical basis.
It affects 2 to 5% of the population in the course of their lives, with a slight female predominance. It is rare before the age of 40, with peak incidence in the 50s.
Etiopathogenesis
Retractile capsulitis is generally idiopathic, or "primary". However, a number of factors have been identified as contributing to the disease:
- Diabetes (10-20% of diabetics will be affected)
- Dysthyroidism (++ hypothyroidism)
- Dyslipidemia
- Autoimmune pathologies
- Prolonged immobilization
Less frequently, it may be secondary to joint trauma (rotator cuff tears, proximal humeral fractures, orthopedic shoulder surgery, glenohumeral subluxations) or muscle spasticity (e.g. following stroke).
Despite various hypotheses, its pathophysiology is still unknown, and even its course is debated (initial inflammatory process? initial fibrosing process? overlap with complex regional syndrome?).
