Definition / general
- Pain, erythema, swelling around bursae that lie between muscles, tendons and bony prominences
- Usually due to chronic trauma (professional athletes in shoulders, pre and infrapatellar bursae of those who kneel); rheumatoid arthritis
- Rarely associated with infection, gout
- Associated with cysts, fluid and loose bodies
- Chronically inflamed bursa may develop extensive calcification
- Subdeltoid bursitis: degeneration of muscle / tendon in shoulder rotator cuff, followed by deposition of calcium in necrotic collagenous tissue, which stimulates inflammatory reaction
Clinical features
- Common sites: shoulder, knee, elbow and hip
- Infrequent sites: interspinous, ischio gluteal, retrocalcaneal
Case reports
- 18 year old woman with interspinous bursitis (J Bone Joint Surg Br 2004;86:1062)
- 45 year old man with subacromial bursitis related to HIV infection (Braz J Infect Dis 2010;14:645)
Treatment
- Varies based on cause of bursitis and changes in bursa
- Includes aspiration, antibiotic irrigation, incision and drainage (for abscess), excision (for thickened bursa)
Gross description
- Thickened, erythematous and shaggy bursal wall with fibrinous exudates
Microscopic (histologic) description
- Chronic inflammation, scarring
