Results were assessed by reviewing the medical records in order to understand the types of fractures commonly seen. The purpose was to evaluate the usefulness of fracture classifications. Key words: fracture types, bone, frequency distribution In this study there was determined the incidence rates of traumatic fractures referred for orthopedic services in a rather large number of patients. Based on a correlation between bone types, fracture localization, fracture line form, the degree of bone fragmentation, age, size, and weight, we had evaluated the frequency distribution for long4bone fractures. Materials and methods There were evaluated 5931 patient records (cats and dogs) admitted in our Clinic, between 2007 and 2011, from witch we catalogued fractures of the appendicular skeleton. Each patient chart contained radiographs (classic and digital) and a surgical descriptive report of the traumatic condition of the patient. In order to find the frequency distribution we classified fractures depending on anatomical part of the bone, fracture line form and the degree of bone fragmentation (2,4,5). Depending on the anatomical part of the bone (localisation) there are: diaphyseal, metaphyseal and epiphyseal fractures. A classification on bone fractures involving fracture line form was: transverse, oblique, spiral and impacted fractures. A fracture distribution depending on the degree of bone fragmentation consists of: simple, comminuted and segmental fractures (1,3). In order to inventory fractures we classified patients by animal size : large, medium and small and very small size. Categorizing animals by age they are divided in: animal under 6 months, young under 1 year, adult, geriatric (large size >6 years, medium and small size >8 years and very small size >10 years). A division depending on patient’s weight reveals many weight categories: 0410 kilograms, 10420, 20430, 30440, 40450 and 504 60 kilograms.
