Comparison of the mid-shaft bone geometry between fractured and non-fractured femora in newborn calves

Akin, Ibrahim

Background: Femoral fractures are one of the most common fractures in newborn calves. Other than trauma, some factors may play a role in femoral fractures in newborn calves. The evaluation of the mid-femoral bone geometry in calves may provide valuable information to the veterinary orthopaedists due to the relationship between the success of the orthopaedic surgery. The purpose of the study was to determine the mid-femoral bone geometry in newborn calves, even if there was difference between fractured and non-fractured femur radiographs.Materials, Methods & Results:Fractured femora in 20 newborn calves were enrolled to study, and 40 femora from 20 age and sex-matched calves without any obvious orthopedic diseases were included. All calves (n: 40) were Holstein, at the age of 1-10 days, weighing 20-45 kg. Mediolateral femur radiographs were taken and measurements of the periosteal (Wp) and endosteal widths (We), as well as cranial (Tcr) and caudal (Tca) cortical thicknesses were performed directly with digital caliper from the mid-shaft of the femora, where the minimum outside diameter and thickest cortex were present. Craniocaudal radiographs were not evaluated due to the abnormal projections. Three consecutive measurements were obtained at once a week interval. A paired t-test and Wilcoxon test was used to determine the differences between the same measurements of the righ
