Ununited anconeal process (UAP) occurs most commonly in German shepherd dogs, but can be seen in many dog breeds. The anconeal process should fuse to the metaphyseal region of the proximal ulna at 4–5 months of age. If the process does not fuse, elbow stability is compromised and osteoarthritis ensues.

Ununited Anconeal Process. Ununited anconeal process (UAP) occurs most commonly in German shepherd dogs, but can be seen in many dog breeds. Surgical treatment is recommended. Arthroscopy allows assessment of the integrity of the anconeal fragment, the degree of fragment stability and the extent of osteoarthritis.

In longstanding, neglected elbow luxations open reduction is carried out in two stages. First a lateral approach is used to allow release of fibrous adhesions so that the radial head and anconeal process can be levered back into their normal position using …

Other common causes of elbow dysplasia included ununited anconeal process (UAP) and fractured or ununited medial coronoid process (FCP or FMCP). Another theory is that this condition is primarily of genetic cause, although environmental factors such as obesity during puppyhood may influence whether an animal with the genes coding for Elbow ...

• Identify early degenerative change (entheseophyte formation) associated with the anconeal process. However, this view rotates the proximal ulna and obscures the margins of the medial coronoid process of the proximal ulna. Therefore, this radiographic projection should only be used to evaluate the anconeal process; not other aspects of the ...

The anconeal process is the cranial process at the proximal end of the trochlear notch.

Two adult domestic shorthair cats were presented with acute forelimb lameness. In 9 one case, there was a history of trauma. A fracture of the anconeal process was 10 diagnosed on the flexed mediolateral radiographs of the elbow in both cats. The 11 fracture was accompanied by a bony avulsion of the tricipital tendon in one animal.

Elbow dysplasia includes three different pathologies: disease of the medial aspect of the coronoid process (MCD); osteochondrosis (OC) or osteochondritis dissecans (OCD) of the medial humeral condyle; ununited anconeal process (UAP).

The un-united anconeal process (UAP) is loose and floating within the joint, and occasionally we have seen this associated with the development of infection in the joint. The floating UAP causes lameness, pain and discomfort, especially on elbow extension.

A fracture of the anconeal process was diagnosed on the flexed mediolateral radiographs of the elbow in both cats. The fracture was accompanied by a bony avulsion of the tricipital tendon in one animal.
