A 13-year-old female spayed mixed breed dog presented to the Cornell University Hospital for Animals for a sudden onset of toe-touching lameness on the left pelvic limb after falling outside. The patient had been hit by a car and sustained a left tibial fracture 25 days prior to this visit, which had been repaired with an 11-hole 3.5mm Locking Compression Plate. The patient had been recovering well after surgery. On presentation, radiographs confirmed that the previously applied bone plate had broken over the fracture line through a screw hole. The failed implant system was removed and replaced with an 8mm interlocking nail. A combination of autogenous cancellous and commercial cortical bone graft was applied to the fracture site. This paper discusses aspects of fracture repair, bone healing, and implant selection, with emphasis on their application to revision strategies.
