Definition
Synovial bursae are small, fluid-filled sacs lined by synovial membrane that are located at sites of friction, such as between tendons and bones or skin. Their primary function is to reduce friction and facilitate smooth movement of the musculoskeletal structures. Native bursae, which are present at predictable anatomical sites, are lined with synovial membrane and contain synovial fluid. Their are classified between their localisation as:
These structures can become inflamed, leading to a condition known as bursitis.[1-2]
The synovial lining of these bursae produces synovial fluid, which acts as a lubricant. Bursae can become distended due to chronic overuse or other pathological processes, and imaging, particularly ultrasound, can reveal fluid collections within the bursa, aiding in diagnosis and management.[1]
