Objective: To report the diagnosis and treatment of a radial artery pseudoaneurysm in a cat. Study Design: Clinical report. Animal: Maine Coon cat (8-year-old neutered male). Methods: Ultrasonographic and angiographic examination of a fluctuant, nonpainful, 3 cm × 1.5 cm subcutaneous swelling on the craniomedial distal aspect of the right radius that occurred 40 days after suspected cat bite trauma was consistent with a radial artery pseudoaneurysm. After ligation of the radial artery proximal to the lesion, the pseudoaneurysm was surgically excised.

A one-year-old neutered male cat was referred for a grade IIIA open radius and ulna fracture. The mid-diaphyseal radial and ulnar fractures were associated with lateral radio-humeral and radio-ulnar dislocations. From these abnormalities, a diagnosis of type IV Monteggia fracture was made. The annular ligament was found to be intact on examination and the radial head was correctly positioned and stable after fracture reduction and plate fixation. Eighteen months postoperatively, the cat did not exhibit any signs of lameness or any signs of pain on palpation and mobilisation.

Eight animals underwent fusion podoplasties for the treatment of chronic interdigital furunculosis (n=3), ectrodactyly (n=1), digit abnormalities associated with tendonectomy (n=1), redundant indertigital skin (n=1), conformational deformity (n=1), and necrotizing fasciitis of the paw (n=1). Median duration of bandaging was 14 days, and median duration of hospitalization was 5 days. Four dogs had dehiscence, which occurred at a mean time of 11 days after surgery. Clinical abnormalities necessitating podoplasty resolved in six animals and improved in two.

A 10-month-old Yorkshire Terrier was referred for evaluation of an intermittent right thoracic limb lameness that acutely progressed to non-weight-bearing. A diagnosis of bilateral bone cysts of the humeral condyles with a pathologic fracture of the lateral aspect of the right humeral condyle was given following radiographic and histopathologic examination. Bilateral pathology necessitated consideration of treatment modalities other than amputation of the limb, as previously reported. Arthrodesis of the right elbow using a 2.0 mm locking bone plate was performed.

The medical records of all cats with tarsocrural joint instability that were treated between June 2002 and December 2008 at the Royal Veterinary College were retrospectively reviewed. A total of 32 cats were identified. Information gathered included signalment, type of injury (subluxation or luxation), concurrent fractures, presence of soft tissue wounds, transarticular external skeletal fixation (TESF) type, configuration of TESF (number of pins proximal and distal to the joint), duration of hospitalisation, duration of TESF prior to removal, complications and cost.

Objective-To assess the effect of computed tomography (CT) scan protocols (radiation amounts) and fabrication methods on biomodel accuracy and variability. Sample-Cadaveric femur of a Basset Hound. Procedures-Retroreconstructions (n = 158) were performed of 16 original scans and were visually inspected to select 17 scans to be used for biomodel fabrication. Biomodels of the 17 scans were made in triplicate by use of 3 freeform fabrication processes (stereolithography, fused deposition modeling, and 3-D printing) for 153 models.

Objective-To compare in vitro axial compression, abaxial compression, and torsional stiffnesses of intact and plated radii from small- and large-breed dogs. Sample-Radii from 18 small-breed and 9 large-breed skeletally mature dogs. Procedures-3 groups were tested: large-breed dog radii plated with 3.5-mm limited-contact dynamic compression plates (LCDCPs), small-breed dog radii plated with 2.0-mm dynamic compression plates (DCPs), and small-breed dog radii plated with 2.0/2.7-mm cut-to-length plates (CTLPs).
