What is the olecranon bursa?

A bursa is a fluid-filled pocket that makes it easier for body parts to move. The olecranon bursa makes it easier for the skin to move over the tip of the elbow when you bend it.

What causes olecranon bursitis?
It’s common for people to develop changes in the bursa with age. It may also be partly inherited (genetic). It’s not clear what role activity plays in the development of olecranon bursitis. Some people get an infection in the bursa. This aid is for people that have fluid or tissue in the bursa, but not an infection. If you’re unsure about this, talk to your doctor.

Olecranon bursitis usually comes to a person’s attention when the bursa fills with fluid. It can get as big as a tennis ball.

How is an olecranon bursitis diagnosed?
Olecranon bursitis is obvious on examination. It’s usually possible to be sure there is no infection just by examining the elbow.
