Abstract
Objective: To assess changes in patient positioning prior to acetabular cup impaction during total hip replacement (THR) procedures in dogs.
Methods: In a prospective, analytical study, 26 client-owned dogs were evaluated for changes in patient positioning during THR procedures. Following initial patient positioning in true lateral recumbency, fluoroscopic measurement of changes in positioning was performed for each plane at 2 separate time points: after draping (M1) and immediately prior to cup impaction (M2).
Results: Patient positioning was significantly altered at time point M1 in the transverse plane, with a mean change of 2.8° (range, 0° to 12°); this change in position was most often toward the dorsum, occurring in 16 of 26 cases (62%). Significant shifting was found at time point M2 in the transverse plane, with a mean change of 2.6° (range, 0° to 10.3°); this change, however, did not significantly correlate with a particular direction. Positioning shifts found at M1 and M2 were not consistently in the same direction in either plane. Body condition score had no effect on shifting found at M1 or M2 in either plane.
Conclusions: Perfect patient positioning is not maintained with the use of bean bag positioners. Despite accurate initial positioning and the use of this positioning device, shifting does occur.
Clinical relevance: Unrecognized shifts in pelvic position during THR procedures may occur, which could contribute to inappropriate implant positioning. Pelvic alignment should be evaluated during THR procedures to minimize the risk of complications.
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.
