Pathogenesis (development of disease)
A stimulus (inflammation, trauma) causes serous fluid to secrete into the bursa.
If there is a chronic change in the bursa, wall thickening occurs, among other symptoms.
Etiology (causes)
Behavioral causes
- Chronic overwork
Disease-related causes
Endocrine, nutritional and metabolic diseases (E00-E90).
- Hyperparathyroidism (parathyroid hyperfunction).
- Hyperuricemia (elevation of uric acid levels in the blood).
Infectious and parasitic diseases (A00-B99).
- Hematogenous (in the bloodstream) spread of various infectious diseases such as gonorrhea, tuberculosis.
- Local infections such as boils
Musculoskeletal system and connective tissue (M00-M99)
- Bursitis calcarea of the shoulder (calcified shoulder).
- Chronic polyarthritis (rheumatoid arthritis).
- Gout (arthritis urica/uric acid-related joint inflammation or tophic gout).
- Bursa abscess – encapsulated accumulation of pus.
- Bursa cyst – encapsulated fluid-filled cavity.
Injuries, poisonings and other consequences of external causes (S00-T98).
- Injuries to the bursa (bursa sac), unspecified.
Laboratory diagnoses – laboratory parameters that are considered independent risk factors.
- Hyperuricemia (elevation of uric acid levels in the blood).
