Abstract
Objective: To evaluate the tensile strength and biomechanical properties of the tension band wire technique using a ring pin in a canine patellar transverse fracture model and to compare it with conventional tension band wire techniques.
Methods: The patella with adjacent structures were harvested from 11 adult canine cadavers and osteotomized transversely. The tension band wiring technique with a single Kirschner wire and metal wire was applied to the KM group (n = 7). The KS group (n = 7) was stabilized with the same technique as the KM group, but a nonabsorbable polyethylene orthopedic suture was used instead of metal wire. The RS group (n = 7) was stabilized with the combination of a ring pin and an orthopedic suture. A single axial tensile force was loaded to the specimens, and the loads at 1-, 2-, and 3-mm displacement and the maximum failure loads were measured.
Results: The mean weight of canine cadavers was 13.7 kg (11.3 to 17.4 kg), and a total of 21 pelvic limbs were used. The RS group showed significantly greater strength compared to the KM group and KS group at maximum failure loads and compared to the KM group at 2- and 3-mm displacement.
Conclusions: The tension band wire technique with a ring pin withstands greater force compared to conventional methods in the canine transverse patellar fractures.
Clinical relevance: The ring pin can be considered a viable option for fractures in dogs primarily requiring resistance to tensile forces.
期刊介绍：
The American Journal of Veterinary Research supports the collaborative exchange of information between researchers and clinicians by publishing novel research findings that bridge the gulf between basic research and clinical practice or that help to translate laboratory research and preclinical studies to the development of clinical trials and clinical practice. The journal welcomes submission of high-quality original studies and review articles in a wide range of scientific fields, including anatomy, anesthesiology, animal welfare, behavior, epidemiology, genetics, heredity, infectious disease, molecular biology, oncology, pharmacology, pathogenic mechanisms, physiology, surgery, theriogenology, toxicology, and vaccinology. Species of interest include production animals, companion animals, equids, exotic animals, birds, reptiles, and wild and marine animals. Reports of laboratory animal studies and studies involving the use of animals as experimental models of human diseases are considered only when the study results are of demonstrable benefit to the species used in the research or to another species of veterinary interest. Other fields of interest or animals species are not necessarily excluded from consideration, but such reports must focus on novel research findings. Submitted papers must make an original and substantial contribution to the veterinary medicine knowledge base; preliminary studies are not appropriate.
