Overview
Bursitis is characterized by inflammation of a bursa and buildup of the fluid in the bursal sac. A bursa is a small, fluid-filled sac that acts as a cushion between a bone and other moving parts: muscles, tendons, or skin. Over 160 bursa are found throughout the body and only few of them can cause bursitis. Based on the nature of inflammation bursitis may classified into 2 subtypes: septic and aseptic. Most common bursitis subtypes include subacromial, olecranon, trochanteric, prepatellar, and retrocalcaneal. Aseptic bursitis can be caused by overused and repetitive injuries to the joint, abnormal bony structure, and crystal deposit in the bursa. Additionally, septic bursitis can be caused by bacterial infection of the bursa through the skin injury following repetitive trauma. Common organism that can lead to septic bursitis include Staphylococcus aureus, Staphylococcus epidermidis, and Streptococcus spp. Bursitis must be differentiated from tendonitis, cellulitis, osteoarthritis, ligamentous injuries, and septic arthritis. The symptoms of bursitis differ based on the location of the inflammation. Focal swelling, pain, and redness are symptoms common to all forms of bursitis. The diagnosis of bursitis is usually made clinically. There are no diagnostic lab findings associated with bursitis. However, patients with septic bursitis may have elevated ESR, CRP, and white blood cells. Ultrasonography may be a useful tool for confirming the diagnosis of bursitis, and aspiration of bursal fluids is usually reserved for the diagnosis of septic bursitis.[1][2] Medical therapy for non-septic bursitis depends on the involved bursa and includes the RICE regimen (rest, ice, compression, elevation), NSAIDs, and/or corticosteroid injections. Restriction of activity is encouraged to prevent further injury and promote healing. Antimicrobials are the mainstay of therapy for septic bursitis. Surgical management is often reserved for non-responders.[3][4][5]
Classification
Based on the nature of inflammation bursitis may classified into 2 subtypes: septic and aseptic. Common anatomic location include shoulder, elbow, hip, knee, and ankle. Most common bursitis subtypes include:[6][7][8][9]
- Subacromial bursitis
- Olecranon bursitis
- Trochanteric bursitis
- Prepatellar bursitis
- Retrocalcaneal bursitis
Pathophysiology
Bursitis is characterized by acute or chronic inflammation of a bursa and buildup of fluid in the bursa sac. A bursa is a small, fluid-filled sac that acts as a cushion between a bone and other moving parts: muscles, tendons, or skin. Over 160 bursa are found throughout the body and only few of them can cause bursitis. Aseptic bursitis can be caused by overused and repetitive injuries to the joint, abnormal bony structure and crystal deposit in the bursa. It commonly affects knee or elbow, from kneeling or leaning on the elbows longer than usual. Moreover, septic bursitis can be caused by bacterial infection of the bursa through the skin injury following repetitive trauma.[7][10][11]
Images
The following are gross and microscopic images associated with bursitis:

Causes
Aseptic bursitis is commonly caused by prolonged pressure, overuse, or strenuous activity. Elbows and knees are the most commonly affected because they are rested upon more than many parts of the body with bursae and they also get the most repetitive use. Shoulder bursitis is more commonly due to overuse of the shoulder joint and muscles. Inflammation of bursae can also be caused by other inflammatory conditions such as rheumatoid arthritis and Spondyloarthritis. Gout and pseudogoutcan also be a cause of bursitis. Common causes of septic bursitis include Staphylococcus aureus, Staphylococcus epidermidis, and Streptococcus spp.[12][13][14][15][1]
Differential Diagnosis
Bursitis symptoms and signs are relatively non-specific. Even after detailed history and physical examination, imaging studies are often necessary to rule out other musculoskeletal conditions. Bursitis must be differentiated from tendonitis, cellulitis, osteoarthritis, ligamentous injuries, and septic arthritis.[7][8][9]
Epidemiology and Demographics
Bursitis accounts for 400 visits per 100,000 visits to primary care clinic. The exact prevalence and incidence of bursitis is unknown.[15]
Risk Factors
Common risk factors in the development of bursitis include rheumatoid arthritis, osteoarthritis, gout, pseudogout cellulitis, diabetes mellitus, use of systemic glucocorticoids, alcoholism, malignancy, and leukopenia. Additionally, having a hobby or job that involves repetitive motions such as bicycling, playing baseball, gardening, or setting tiles may lead to bursitis.[15]
Screening
Screening for bursitis is not recommended.[16]
Natural History, Complications, and Prognosis
Bursitis is often caused by overused and repetitive injuries to the join. Symptoms of bursitis may develop rapidly within 2 to 3 days in an acute form. It usually presents with edema, erythema, and tenderness over the involved joint. In most cases after adjustment of activities, bursitis will gradually clear within few days to weeks without any long-term consequences. If left untreated, acute bursitis may lead to chronic bursitis which may result in cicatricial adhesions, reduced mobility, and progressive pain. With treatment and activities adjustment, septic and aseptic bursitis are associated with excellent prognosis.
Diagnosis
History
Complete history will help determine whether the bursitis is associated with any specific activities.[7][8][9]
Symptoms and Physical Examination
| Type of Bursitis | Symptoms | Physical examination |
|---|---|---|
| Subacromial bursitis[8] |
|
|
| Olecranon bursitis[17][18] |
|
|
| Trochanteric bursitis[19][20] |
|
|
| Prepatellar bursitis[9][21] |
|
|
| Retrocalcaneal bursitis[7][22] |

Laboratory Findings
The diagnosis of bursitis is usually made clinically. There are no diagnostic lab findings associated with bursitis. However, patients with septic bursitis may have elevated ESR, CRP, and white blood cells.[23][24][25]
X ray
X ray is not often required in patients with bursitis. X ray may be used as a diagnostic measure to support a clinical diagnosis of bursitis. Joint x ray is generally reserved for patients with history of significant trauma. A plain x ray may be helpful in the diagnosis of fracture or dislocation.[26][21][27]
CT
CT scan is not often required in patients with bursitis. It is usually reserved for the patients who are not responding to initial treatment. On CT scan, superficial bursitis may be characterized by fluid density at the subcutaneous tissue.[26][21]
MRI
MRI is not often required in patients with bursitis. Due to the cost and time, the use of MRI is limited compere to ultrasound. MRI is often reserved for patients who are highly suspicious of other medical conditions such as tumors, ligamentous injures, and tendon injuries. On MRI, bursitis is characterized by bursal fluid collection, subcutaneous edema and joint effusion.[26][21]
Ultrasound
Ultrasonography may be a useful tool for confirming the diagnoses of bursitis. On ultrasound, bursitis may be characterized by bursal wall distention with presence of local hypoechoic or anechoic intra-bursal material, synovial proliferation, calcifications, and rheumatoid nodules.[28][29]
Other Diagnostic Studies
Other diagnostic study for bursitis include aspiration of the bursal fluid. Aspiration of bursal fluids is not recommended in the management of all types of bursitis. It is usually reserved for the diagnosis of septic bursitis.[1][2]
Treatment
Medical Therapy
Medical therapy for non-septic bursitis depends on the involved bursa and includes the RICE regimen (rest, ice, compression, elevation), NSAIDs, and/or corticosteroid injections. Restriction of activity is encouraged to prevent further injury and promote healing. Antimicrobials are the mainstay of therapy for septic bursitis. Surgical management is often reserved for non-responders.[3][4][5]
| Septic[3][4] | Aseptic |
|---|---|

Surgery
Surgical intervention is not recommended for the management of bursitis. However, surgical techniques include bursectomy and Longitudinal band release are usually reserved for patients with chronic, recurrent, or septic bursitis.[30]
Primary Prevention
Effective measures for the primary prevention of bursitis include maintaining a healthy weight, taking breaks from repetitive tasks, using foam for kneeling and elbow pads, and practicing good posture and position.[31]
Secondary Prevention
There are no established method for secondary prevention of bursitis. However, activities adjustment and using foam for kneeling or elbow pads, and resting while doing repetitive tasks may be lead to the fast recovery.[31][32]
