Palpation and dorsal acetabular rim radiographic projection for early detection of canine hip dysplasia: a prospective study.

Objective: To determine the value of 2 diagnostic methods: (1) the reduction angle (RA) using the Ortolani maneuver and (2) the dorsal acetabular slope (DAS) from the dorsal acetabular rim (DAR) radiographic projection, to predict osteoarthritis (OA) in dogs with hip dysplasia.

Study Design: Prospective study.

Sample Population: Dogs (n = 73).

Radiographic abnormalities in cats with feline bronchial disease and intra- and interobserver variability in radiographic interpretation: 40 cases (1999-2006).

Objective: To determine prevalence of various radiographic signs in cats with feline bronchial disease (FBD) and evaluate intra- and interobserver variability in radiographic interpretation for examiners with variable degrees of experience in radiographic interpretation.

Design: Retrospective case series.

Animals: 40 cats with FBD and 40 control cats without thoracic disease.

Radiographic detection of thoracic lesions in adult cows: a retrospective study of 42 cases (1995-2002).

Medical records of 42 cows that underwent both thoracic radiographic and postmortem examinations within a period of 7 days were reviewed to develop an evaluation grid to interpret bovine thoracic radiographs and to determine the sensitivity and the specificity of thoracic radiographs for detection of thoracic lesions, based on postmortem examination. Most cows (64%) had clinical signs of respiratory disease, whereas 19% showed signs of cardiac problems. The sensitivity and specificity of radiographs for identifying cows with thoracic lesions were 94% and 50%, respectively.

Sensitivity and specificity of radiographic detection of canine elbow incongruence in an in vitro model.

Canine elbow incongruence is believed to be the consequence of underdevelopment of the radius. The purpose of this study is to determine the sensitivity and specificity of radiography to detect elbow incongruence in an in vitro model and to assess the optimal elbow angle and radiographic beam position. Five normal cadaveric canine left forelimbs were used.

Comparison of multistage versus one-stage destabilization of a type II external fixator used to stabilize an oblique tibial osteotomy in dogs.

Objective: To compare the biomechanical effects of multistage versus one-stage destabilization of a type II external skeletal fixator (ESF) used to stabilize an oblique unstable tibial osteotomy in dogs.

Study Design: In vitro, in vivo, and ex vivo experimental study.

Animal Population: Twelve healthy adult dogs.
