Ulnar ostectomy decreases the stability of canine cadaver carpi as assessed with stress radiography.

Distal ulnar ostectomy may be performed palliatively in patients with distal ulnar osteosarcoma. Concurrent arthrodesis of the carpus has been proposed to counteract joint instability following transection of carpal ligaments associated with removal of the distal ulna. The objective of this prospective one group pretest, posttest study was to assess stability of the carpus following distal ulnar ostectomy using pre- and postoperative stress radiographic views in a group of canine cadaver limbs.

Effect of distal ulnar ostectomy on carpal joint stability during weight bearing in the dog.

Objective: To assess the influence of a 50% distal ulnectomy on mediolateral carpal stability in the dog.

Study Design: Canine cadaveric study.

Sample Population: Seven canine thoracic limbs METHODS: Thoracic limbs were placed in a jig to mimic weight bearing with a load representing 30% of body weight.

A valentine-shaped cardiac silhouette in feline thoracic radiographs is primarily due to left atrial enlargement.

Conflicting information has been published regarding the cause of a valentine-shaped cardiac silhouette in dorsoventral or ventrodorsal thoracic radiographs in cats. The purpose of this retrospective, cross-sectional study was to test the hypothesis that the valentine shape is primarily due to left atrial enlargement. Images for cats with a radiographic valentine-shaped cardiac silhouette and full echocardiography examination were retrieved and independently reviewed.

Thoracic radiographic anatomy in vervet monkeys (Chlorocebus sabaeus).

Background: The vervet monkey (Chlorocebus sabaeus) is used commonly in cardiorespiratory biomedical research. This study was performed to establish reference values for thoracic structures and to describe the normal radiographic appearance of the vervet monkey thorax.

Methods: Right lateral and dorsoventral thoracic radiographs of ten mature vervet monkeys were evaluated.
