Biomedical Sciences

The Department of Biomedical Sciences aims to provide knowledge of anatomy and physiology in order to understand the mechanisms and treatment of animal diseases. Additionally, it seeks to teach the understanding of drug-action for rational drug-therapy, as well as toxicology, pharmacodynamics, and clinical drug administration.

History
The Department of Biomedical Sciences was formed in 1999 as a merger of the Department of Veterinary Anatomy and the Department of Veterinary Physiology and Pharmacology.

Dates of Existence
1999–present

Organizational Unit
Veterinary Clinical Sciences
The mission of the Veterinary Clinical Sciences Department and the Veterinary Medical Center is to be strong academically, to provide outstanding services, and to conduct research in the multiple areas of Veterinary Clinical Sciences. Our goals are to teach students in the multiple disciplines of Veterinary Clinical Sciences, to provide excellent veterinary services to clients, and to generate and disseminate new knowledge in the areas of Veterinary Clinical Sciences. Our objectives are to provide a curriculum in the various aspects of Veterinary Clinical Sciences which ensures students acquire the skills and knowledge to be successful in their chosen careers. We also strive to maintain a caseload of sufficient size and diversity which insures a broad clinical experience for students, residents, and faculty. In addition, we aim to provide clinical veterinary services of the highest standards to animal owners and to referring veterinarians. And finally, we strive to provide an environment and opportunities which foster and encourage the generation and dissemination of new knowledge in many of the disciplines of Veterinary Clinical Sciences.
Organizational Unit
Veterinary Diagnostic and Production Animal Medicine
The mission of VDPAM is to educate current and future food animal veterinarians, population medicine scientists and stakeholders by increasing our understanding of issues that impact the health, productivity and well-being of food and fiber producing animals; developing innovative solutions for animal health and food safety; and providing the highest quality, most comprehensive clinical practice and diagnostic services. Our department is made up of highly trained specialists who span a wide range of veterinary disciplines and species interests. We have faculty of all ranks with expertise in diagnostics, medicine, surgery, pathology, microbiology, epidemiology, public health, and production medicine. Most have earned certification from specialty boards. Dozens of additional scientists and laboratory technicians support the research and service components of our department.

Abstract

Objective: To determine the influence of plating systems on the clinical outcomes in dogs treated for ilial fractures.

Design: Retrospective study.

Animals: Fifty‐nine dogs (63 hemipelves).

Methods: Radiographs and medical records of dogs with ilial fractures presented to Iowa State University between 2003 and 2019 were reviewed. After fracture reduction, fractures were fixed with a locking plate system (LPS) or non‐locking plate system (NLS). Perioperative, long‐term complications, and follow‐up data were recorded. The frequency of implant failure and pelvic collapse were compared using a logistic and linear regression analysis, respectively. Where the univariate test was statistically significant, a multivariate analysis across categories was performed to identify statistically different categories.

Results: LPS and NLS implants were used in 25/63 and 38/63 hemipelves, respectively. Median follow‐up time was 8 weeks (3–624 weeks). Implant failure occurred in 18/63 (29%) of fracture repairs, consisting of 17 with NLS and 1 with LPS. Revision surgery was recommended in five cases of implant failure, all with NLS. The probability of implant failure was higher when fractures were fixed with NLS (p = .0056). All other variables evaluated did not seem to influence outcome measures.

Conclusion: The variable with the most influence on the outcomes of dogs treated for ilial fractures consisted of the fixation method (NLS vs. LPS). Fractures repaired with NLS were nearly 20 times more likely to fail than those repaired with LPS.

Clinical Relevance: Surgeons should consider repairing ilial body fractures in dogs with LPS to reduce the risk of short‐term implant failure.
