OBJECTIVES: To investigate whether West Highland white terriers exhibit significant variation in the position of the medial fabella compared to both small and large breed dogs. METHODS: Criteria for the normal location of the medial fabella on a caudocranial radiograph were established. A retrospective analysis was undertaken of a consecutive series of bilateral caudocranial stifle joint radiographs from 70 West Highland white terriers, 100 small and 100 large control dogs by three reviewers.

The purpose of this study was to evaluate the utility of single-detector computed tomographic arthrography (CT arthrography) for the diagnosis of cranial and caudal cruciate ligament and meniscal lesions in the dog stifle. Four normal and 25 abnormal stifle joints, determined to have lesions related to intra-articular ligamentous insufficiency based on clinical history, orthopedic examination, and survey orthogonal radiographs, were imaged using a previously developed CT arthrography protocol. Surgery was performed immediately following the CT procedure.

Objective-To evaluate skeletal characteristics of pelvic limbs with and without cranial cruciate ligament (CCL) deficiency in Labrador Retrievers. Animals-30 adult purebred Labrador Retrievers. Procedures-Pelvic limbs (n = 28) of 14 dogs without CCL deficiency were classified as control limbs, whereas the limbs of 16 dogs with CCL deficiency were considered affected by (18 limbs) or predisposed to (10 contralateral limbs of dogs with 1 affected limb) CCL deficiency. Skeletal characteristics were evaluated via physical examination, radiography, and computed tomography.

Ten cats with a mean age of eight years and five months had suffered proximal transverse tibial fractures; in four of them both tibiae had fractured at different times. All the cats also had bilateral non-union patellar fractures, and nine of them had evidence of fractures elsewhere, including acetabular, ischial, humeral condylar and rib fractures, which had occurred before or after the tibial fractures. All the tibial fractures were proximal and transverse.

Patients at the Blue Star Foundation animal hospital in Gothenburg, Sweden, underwent a procedure with an extracapsular suture technique for cranial cruciate ligament rupture. Two groups were compared; one of the groups received rehabilitation by the owner, and the other received professional rehabilitation by a trained physiotherapists. The dogs where reexamined at four, 12 and 24 weeks postoperatively. The results were 'good' in both groups but a difference was not seen between the groups.

The objective of the present study was to determine the tibial plateau angle (TPA) in cats without stifle pathology and to compare it with cats suffering from an isolated cranial cruciate ligament rupture. Mediolateral radiographs of the stifle were taken and the tibial plateau angle was measured based on the method previously described by Slocum and Devine (1983) for dogs. Three observers with different levels of experience evaluated the radiographs of all of the cats in this study.

OBJECTIVE: To compare values for tibial plateau angle (TPA) obtained in dogs by conventional and digital methods. DESIGN: Evaluation study. ANIMALS: 37 dogs with stifle joint abnormalities. PROCEDURES: In all dogs, radiographs of both stifle joints were obtained by conventional and digital means. On conventionally acquired radiographs, TPA was measured with a protractor and fine-point pencil in accordance with standard guidelines. A software program was used to measure TPA on digitally acquired radiographs. Two viewers with different levels of experience performed all measurements 3 times.

A lateral tibial head buttress plate designed for human beings was used to repair a highly comminuted tibial fracture in a two-year-old male labrador retriever caused by a gunshot wound. The plate was placed in a bridging fashion to provide minimal disruption of the fracture site and minimise surgical time.
