  • The use of ultrasonography has been shown to be extremely effective in the diagnosis of olecranon bursitis and other soft-tissue lesions in the olecranon area by rapidly demonstrating the presence of effusions, synovial proliferation, loose bodies, increased blood flow consistent with inflammation, tendonitis with calcifications, and other indications of bursitis.

  • If an infectious etiology is suspected (due to the presence of fever, erythema, previous puncture wounds, or cellulitis), the olecranon bursa should be aspirated and the fluid sent for culture, for a cell count (white blood cells [WBCs], red blood cells [RBCs]), and for Gram staining for bacteria.
