Abstract
Objective: To evaluate the accuracy of dog positioning before total hip replacement (THR) and the influence of experience and dog body condition score (BCS) on positioning accuracy.
Methods: 6 experienced THR surgeons and 11 veterinarians without THR experience positioned 4 cadavers (2 each with BCSs of 4/9 and 6/9) for THR 3 times using a vacuum bean bag. Accuracy was evaluated using fluoroscopy in 2 orthogonal planes: the transverse and dorsal planes.
Results: Mean positioning error was < 4° in both the transverse and dorsal planes. The mean deviation in the transverse plane for veterinarians with THR experience (3.6°) did not differ from the deviation for veterinarians without experience (3.8°; P = .398). The mean absolute deviation in the dorsal plane for veterinarians with THR experience (3.2°) did not differ from the mean absolute deviation for veterinarians without experience (3.7°; P = .930). Malpositioning > 10° in either plane occurred in 17 of 204 positionings (8%) and did not differ in frequency among experienced and inexperienced veterinarians. No difference in positioning accuracy was noted between cadaver BCS groups.
Conclusions: Freehand patient positioning before THR is generally precise and does not appear to improve with additional experience or lean patient BCS.
Clinical relevance: Most dogs positioned using a vacuum bean bag and freehand (nonfluoroscopy guided) positioning are accurately positioned, and positioning errors > 10° occur < 10% of the time. Positioning accuracy may not increase with lean patient BCS or additional experience for veterinary surgeons doing THR.
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.
