ItemInvestigations of vertebral and other skeletal abnormalities causing lameness and loss of performance in horses( 1988)This thesis contains a collection of publications which are submitted for examination for the degree of Doctor of Veterinary Science in the University of Melbourne. The work presented here involves a continuing investigation into the underlying causes of poor performance and gait abnormalities in horses. Section 1 provides an introduction to the thesis by considering the concept of "wastage" or reduced performance in racehorses and highlights the role of lameness. It is clear that more sophisticated and objective techniques of assessment (eg locomotion analysis and noninvasive bone measurement) are going to be essential if the current disastrous level of economic wastage is to be effectively reduced. The ensuing sections consider the author's investigations into some of the more difficult to diagnose forms of lameness in horses. Section 2 deals with the investigation and management of thoracolumbar conditions which pose some of the most perplexing problems faced by veterinarians today in practice. These publications attempt to shed some light into this controversial area by presenting a protocol for evaluation and diagnosis of conditions affecting the vertebral column. Section 3 covers similar ground concerning the pelvic girdle while Section 4 considers problems affecting the stifle joint. Section 5 deals with an emerging technique of noninvasive bone measurement, which appears to have important applications in assessing skeletal maturity and bone quality, as well as performance and exercise physiology. Each Section is headed by a short explanatory note. Colleagues who shared in the work are recognized as co-authors and other help is acknowledged in each paper. In the case of collaborative work each section or subsection is preceded by a Statement on Share of Work to indicate my part in the planning, execution and publication of the work described.
