Bursitis

Disease Description (Causes and Symptoms)

• Definition: Bursitis is a condition in which the bursa around a joint becomes inflamed. A bursa is a small lubricating sac that reduces friction between tendons, muscles, bones, and skin.
• Common locations: The shoulder (scapular region), elbow, hip, knee, buttocks, and other areas subject to frequent repetitive friction.
• Causes
  • Repetitive friction, overuse, or sustained pressure (e.g., work that involves kneeling or working overhead for long periods)
  • Hemorrhage into the bursa caused by direct trauma
  • Septic (infectious) bursitis caused by bacterial infection, particularly Staphylococcus aureus
  • Systemic inflammatory diseases (rheumatoid arthritis), tuberculous infiltration such as tuberculosis, and crystal-related diseases such as gout
• Pathophysiology: Inflammation and effusion develop in the bursa, causing it to expand, producing pain and tenderness in surrounding tissues, and restricting joint movement. In cases of infection, fever, erythema, and localized warmth may occur.
• Main symptoms
  • Localized pain and tenderness
  • Swelling (a lump- or blister-like enlargement)
  • Restricted movement of the joint or surrounding tissues
  • In infectious cases, redness, warmth, fever, and systemic symptoms
• Diagnosis (brief)
  • Clinical examination is key (assessment of swelling, tenderness, and range of motion)
  • Ultrasound: useful for evaluating fluid and inflammation within the bursa
  • Radiography (X-ray): to rule out bone lesions
  • Bursa aspiration (of the observed fluid), cytology, and culture: necessary to differentiate infectious or crystal-related bursitis (gout)
  • Blood tests: inflammatory markers such as white blood cell count, CRP, and ESR

Treatment Methods

• Conservative treatment (initial)
  • Rest and limiting use of the affected area
  • Ice application (during the acute phase, for 48–72 hours), followed by a possible switch to warm compresses
  • Compression bandage or protective equipment (e.g., knee pads)
  • Controlling pain and inflammation with anti-inflammatory drugs (NSAIDs)
  • Physical therapy (stretching and strengthening, correction of posture and work environment)
• Medication treatment
  • If infection is suspected, administer appropriate antibiotics after aspiration (the choice between oral and intravenous administration depends on the severity of the infection)
  • In noninfectious cases, local steroid injection into the joint (infection must be ruled out before injection)
• Procedures/Surgery
  • Diagnostic and therapeutic aspiration (drainage of fluid): to determine whether infection is present and relieve pressure
  • If the condition repeatedly recurs or conservative treatment fails, surgical bursectomy may rarely be considered
• Precautions and self-care
  • If infection is suspected (severe pain, redness, or fever), seek medical attention immediately
  • Steroid injections should be performed only after infection has been completely ruled out
  • Patients taking anticoagulants: consult medical staff before aspiration or injection (risk of bleeding)
  • Correct repetitive factors (work posture and overuse): use protective equipment, adjust work height, and so on
• Complications
  • Chronic pain and restricted movement, with repeated recurrence
  • Osteomyelitis or sepsis if the infection spreads throughout the body (rare)
  • Possible accompanying calcification or problems involving nearby tendons

Outpatient Visit Checklist (Including Example Questions)

• Items and records to prepare
  • Current medications (especially anticoagulants, antiplatelet agents, immunosuppressants, and steroids)
  • Allergies (especially to antibiotics, local anesthetics, and others)
  • Whether there has been a recent fever and any recorded temperatures
  • The time symptoms began, changes in symptoms (intensity and frequency), and triggering factors (trauma or repetitive work)
  • Previous test results (X-ray, ultrasound, and blood tests), as well as imaging films/CDs or photographs
  • Attempts to relieve pain (medications, assistive devices, physical therapy, and so on) and their effects
• Tests that may be performed during the outpatient visit
  • Physical examination (checking range of motion, tenderness, and redness)
  • Ultrasound and, if necessary, X-ray
  • Bursa aspiration if indicated (explanation and consent regarding the purpose and process of the test are required)
  • Blood tests (infection markers)
• Example questions (phrases patients can prepare themselves)
  • "When did the symptoms begin, and which movements make them worse?"
  • "Do you have a list of the medications you are currently taking, especially anticoagulants?"

Examples of General Questions to Ask the Doctor

• What do you think is causing this condition?
• How can you confirm whether there is an infection? Do I need aspiration?
• What are the side effects of the medications (antibiotics, anti-inflammatory drugs, and steroid injections)?
• How soon can I return to work or exercise?
• What lifestyle or work-related recommendations can help reduce recurrence?
• How likely is it that surgery will be necessary? What are the risks of surgery?

Examples of Condition-Specific Questions

• What tests are needed to determine whether the bursitis in this area is bacterial (infectious), and what care is needed before and after aspiration?
• If bursitis repeatedly recurs and conservative treatment is insufficient, when should surgery (removal of the bursa) be considered? What are the recovery period and recurrence rate after surgery?
