Causes

Olecranon bursitis can arise from an injury to the elbow, prolonged leaning on the elbows during physical work and an infection caused by a laceration to the elbow. It also occurs in patients with medical conditions that affect the joints such as gout and rheumatoid arthritis. Various mechanisms can lead to olecranon bursitis:

Acute direct injury (aseptic)

Repetitive microtraumas

Prolonged pressure on the elbow (aseptic)

Infection (septic)
