Enthesitis is inflammation of the entheses (singular: enthesis), the sites where tendons, ligaments and joint capsules attach to bones. [1] [2] It is a type of enthesopathy, meaning any pathologic condition of the entheses, with or without inflammation.

Close to the elbow, the ulna has a bony process, the olecranon process, a hook-like structure that fits into the olecranon fossa of the humerus. This prevents hyperextension and forms a hinge joint with the trochlea of the humerus. There is also a radial notch for the head of the radius, and the ulnar tuberosity to which muscles attach.
A harvested tendon, such as the palmaris tendon [11] from the forearm of the same or opposite elbow, the patellar tendon, hamstring, toe extensor or a donor's tendon , is then woven in a figure-eight pattern through the holes and anchored. [10] The ulnar nerve is usually moved to prevent pain, as scar tissue can apply pressure to the nerve. [11]
The olecranon is situated at the proximal end of the ulna, one of the two bones in the forearm. [1] When the hand faces forward the olecranon faces towards the back (posteriorly). It is bent forward at the summit so as to present a prominent lip which is received into the olecranon fossa of the humerus during extension of the forearm. [2] [3]

The flexor carpi ulnaris has two heads; a humeral head and ulnar head. The humeral head originates from the medial epicondyle of the humerus via the common flexor tendon. The ulnar head originates from the medial margin of the olecranon of the ulna and the upper two-thirds of the dorsal border of the ulna by an aponeurosis.
