Elbow bursae
The elbow bursae are a collection of synovial-lined bursae that exist around the elbow. They can be divided into bursae around the olecranon and in the cubital fossa.
Olecranon bursae
- superficial olecranon bursa: lies between the olecranon and the subcutaneous tissue.
- subtendinous olecranon bursa: lies between the tip of the olecranon and deep to the triceps brachii tendon .
- intratendinous olecranon bursa: lies within the triceps brachii tendon near its insertion onto the olecranon .
Cubital bursae
- bicipitoradial bursa: lies between the distal biceps brachii tendon and the tuberosity of the radius .
- interosseous bursa: lies along side the brachialis muscle and adjacent to the biceps brachii tendon in the medial antecubital fossa. It occurs in ~20% of individuals .
Others
Other less common bursae include
- olecranon bursa (can have several components)
- subcutaneous bursa of medial epicondyle
- subcutaneous bursa of lateral epicondyle
- bursa of anconeus / subanconeous bursae
- bursa at origin of extensor carpi radialis brevis
