A hypoattenuating lesion in the left humeral condyle of an American cocker spaniel consistent with partial incomplete ossification of the humeral condyle was observed on computed tomography. Left forelimb lameness developed over the following three weeks at which time repeat computed tomography examination confirmed propagation of the lesion. Lameness resolved following placement of a transcondylar positional screw, suggesting that lameness was secondary to condylar instability. To the authors' knowledge this is the first report of propagation of an intracondylar lesion in a dog.
Propagation of a partial incomplete ossification of the humeral condyle in an American cocker spaniel.
Objective: To characterise the humeral trochlea in middle to large breed dogs in respect to split-line pattern and cartilage thickness. Methods: In 15 paired cadaveric elbow joints of mature dogs (>20 kg body weight) collagen network orientation of the hyaline cartilage of the humeral trochlea was visualised using a traditional split-line technique in which a dissecting needle dipped in India ink was inserted into the cartilage (n = 10).
Evaluation of radiographic and genetic aspects of hereditary subluxation of the radial head in Bouviers des Flandres.
Objective-To study radiographic and genetic aspects of hereditary radial head subluxation in Bouviers des Flandres. Animals-26 related Bouviers des Flandres affected with bilateral subluxation of the radial head, 10 unaffected related dogs, and 29 unrelated Bouviers des Flandres with diagnoses of nonskeletal diseases. Procedures-All dogs were radiographically studied, and their DNA was analyzed with a genome-wide screen of 1,536 single nucleotide polymorphisms. In addition, karyotyping was performed in an unaffected dam and its affected offspring.
Comparison of five radiographic views for assessment of the medial aspect of the humeral condyle in dogs with osteochondritis dissecans.
OBJECTIVE: To compare 5 radiographic views for the detection of osteochondritis dissecans (OCD) in dogs with signs of elbow joint pain. ANIMALS: 53 dogs (100 elbow joints) with forelimb lameness and signs of elbow joint pain. PROCEDURES: Mediolateral (ML), flexed ML, craniocaudal (CC), craniolateral-caudomedial oblique (Cr15L-CdMO), and distomedial-proximolateral oblique (Di35M-PrLO) radiographic views of the 100 elbow joints were obtained. Four examiners graded radiographs with regard to elbow joint OCD. Joints were assessed by use of arthroscopy.

OBJECTIVES: To describe the normal anatomy of the soft tissues stabilizing the canine elbow observed by magnetic resonance (MR) imaging. STUDY DESIGN: Descriptive study. ANIMALS: Cadavers of large breed dogs (n=3). METHODS: Immediately after euthanasia, T1- and T2-weighted MR images of both elbows of each dog were made in sagittal, transverse, and dorsal planes. Elbows were removed from the cadavers, embedded in a water bath, and frozen. Slab sections of the frozen elbows were obtained and matched with the MR images.

Abstract CLINICAL PRESENTATION: A 12-year-old spayed domestic crossbred cat presented because she would not walk down stairs. A firm swelling on the medial aspect of the elbow was detected during physical examination. The lesion was not hot or painful on palpation and the lameness was mild, but the elbow had a reduced range of motion compared with the contralateral limb.

Two adult Domestic Shorthaired cats were presented with acute forelimb lameness. In one case, there was a history of trauma. 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. Both cats underwent surgical removal of the fractured anconeal process. Follow-up radiographic evaluation was available for one cat six months after treatment; radiographs showed evidence of osteoarthritis.
Objectives: To describe the relationship of the major muscular, ligamentous and neurovascular structures in relation to standard medial elbow arthroscopic portals used in dogs, and to evaluate their potential iatrogenic lesions. Design: Anatomical study using 20 canine cadaveric elbows. Methods: Arthroscopic explorations were performed using medial portals. Three 4 mm orthopaedic pins were introduced in place of the arthroscope, egress canula and instrumental portals. Limbs were dissected. Distances between pins and neurovascular structures were measured.
