Internal fixation of canine coccygeal vertebral fractures: four cases (2018‐2022)

Abstract

ObjectivesTo describe the surgical technique and evaluate the outcome and complications after coccygeal vertebral fracture repair in dogs using internal fixation.Materials and MethodsMedical records and radiography of client‐owned dogs were reviewed retrospectively. A lateral approach to the vertebral body was used, and a 1.5 or 1.0 mm plate was applied laterally. Initial follow‐up included clinical and radiographic assessment at 6 to 8 weeks postoperatively. Short‐term follow‐up was assessed by the completion of an adapted functional questionnaire by owners.ResultsFour dogs presented with mid‐vertebral body fractures. The neurological function of the tail was preserved, and fracture repair was performed in all cases. One dog developed a surgical site infection, which was successfully treated with antimicrobial therapy. One dog experienced prolonged postoperative pain and delayed union. Fracture healing occurred in all patients at the final follow‐up. Neither discomfort nor reduced function or mobility of the tails was noticed during the postoperative patient assessment. The questionnaire was completed by all owners with a mean follow‐up time of 40 weeks. Excellent outcomes were established from subsequent clinical reviews and owner questionnaires, related to their dog's activity and comfort levels.Clinical SignificanceExcellent outcomes can be achieved following the repair of coccygeal vertebral fractures in dogs using internal fixation, including a return to normal function of the tail.
