Abstract

The present retrospective study investigated the localization, cause, treatment and healing of long bone fractures in cattle. Over a period of ten years, medical records of 194 cattle of all ages with a long bone fracture, presented at the Clinic for Ruminants with Ambulatory and Herd Health Services at LMU Munich, were evaluated. The majority of patients (n = 131, 67.5%) were younger than two weeks of age. Of these, 118 calves sustained the fracture on the day of birth (60.8%). An obstetrical assistance was found in 57.4% (n = 58) of birth-related cases as a fracture cause. The femur was most frequently affected in calves aged up to two weeks (n = 35;26.7%). The second most frequent fractures occurred in the metacarpus (n = 31;22.9%) in this age group, followed by metatarsus (n = 28;21.4%) and tibia (n = 27;20.6%). Fractures of the antebrachium (n = 9;6.9 0 /o) and the humerus were rare (n = 1;0.8%). A total of 194 patients were diagnosed with 50 femur fractures (25.8%), 53 metacarpal fractures (27.3%), 43 metatarsal fractures (22.2%), 30 tibial fractures (15.5%), 11 antebrachial fractures (5.7%) and 7 humeral fractures (3.6%). Of the 194 animals, 78 (40.2%) had to be euthanized, 42 of them (53.8%) without treatment. In 150 patients, treatment was initiated, of which 110 patients (73.3%) were dismissed healthy from the clinic. Among the conservative treatment methods were stall rest, casts, casts combined with a U-shaped metal rail (walking casts) and the Thomas splint. Surgical therapy (internal fixation with plates or screws, transfixation pin casts) was used to treat 65 animals (33.5%). While 86.9% (74 out of 85) of the conservatively treated animals left the clinic alive, it were only 58.1 0 /o (36 out of 65) animals after surgical treatment. In the newborn calves, colostrum supply had a significant effect on the success of the treatment. If the gamma-glutamyl transferase concentration was below 200 IU/L in the calves aged under 4 days, the healing rate was significantly different from the cure rate of sufficiently immunized patients (26.9% (7 out of 26) vs. 65.3% (47 out of 72), P = 0.001).
