Overview
Based on the nature of the inflammation, bursitis may classified into two subtypes: septic and aseptic. Common anatomic location include the shoulder, elbow, hip, knee, and ankle. The most common bursitis subtypes include subacromial, olecranon, trochanteric, prepatellar, and retrocalcaneal. Moreover, based on the location of the affected bursa in relation to the skin, bursitis may be further classified into two additional subtypes: superficial and deep. Superficial bursa are more prone to get infected with bacteria and develop septic bursitis. Common locations of septic bursitis include the knee (prepatellar bursitis) and elbow (olecranon bursitis).[1][2][3][4]
Classification
Based on the nature of inflammation bursitis may classified as:[1][2][3][4]
Common anatomic locations include:
- Elbow bursae
- Shoulder bursae
- Subacromial/subdeltoid bursa
- Subscapularis recess
- Subcoracoid bursa
- Coracoclavicular bursa
- Supra-acromial bursa
- Hip bursae
- Trochanteric bursa
- Iliopsoas bursa
- Subgluteus medius bursa
- Subgluteus minimus bursa
- Knee bursae
- Prepatellar bursa
- Infrapatellar bursa
- Suprapatellar bursa
- Medial collateral ligament bursa
- Baker's cyst
- pes anserine bursa
- Ankle bursae
- Retrocalcaneal bursa
- Achilles bursea
Based on the location of the affected bursa in relation to the skin, bursitis may be further classified into two subtypes: superficial and deep.
- Common superficial forms of bursitis include:
- Olecranon bursitis
- Prepatellar bursitis
- Infrapatellar bursitis
- Retrocalcanea bursitis
- Common deep forms of bursitis include:
- Trochanteric bursitis
- Anserine bursitis
- Subacromial bursitis
Additionally, based on duration of symptoms and presentation bursitis may classified as acute, subacute or chronic.
