Abstract

To evaluate a dowel pinning technique for metacarpal and metatarsal fractures in dogs. Medical records of 13 dogs with complete clinical and radiographic follow-up examinations after a median observation time of 5 months were evaluated retrospectively. Assessment included fracture data, number of stabilized bones versus number of fractured bones and parameters of internal fixation including postoperative axial alignment and position of implants assessed on serial radiographs. Complications during the healing period and the final radiographic and functional outcome were analysed in relation to the details of fracture fixation. Most dogs in this study (mean age: 2.9 years, mean weight: 9.9 kg) had fractures of three or four bones, and fractures were closed in all but one dog. All fractures involved the metacarpal/metatarsal body, and all but five were transverse. The size of Kirschner wires used for dowel pinning ranged from 0.8 to 2.0 mm, and the length in relation to bone length ranged from 39 to 91%. Axial alignment of internal fixation was and remained anatomically correct and the dowel pins remained in place in all but one dog. This dog had open metatarsal fractures and dowel pinning was contraindicated. Additionally, the Ki...Continue Reading
