title: Suspected intramedullary bone infarct subsequent to tibial plateau levelling osteotomy in a dog.
abstract: BACKGROUND
  Bone infarction is a syndrome associated with disruption to the medullary blood supply of a long bone and may present as either a cause of lameness or, more commonly, an incidental finding. Bone infarction is a known complication of total hip replacement in the dog and may be associated with several other systemic diseases.
  
  
  METHODS
  A 3-year-old female desexed Labrador Retriever presented for acute lameness 4 weeks following tibial plateau levelling osteotomy (TPLO). Subsequent radiographs revealed an increase in medullary bone opacity, radiographically consistent with a medullary bone infarction. The lesion was followed with serial radiographs and appeared to spontaneously resolve.
  
  
  CONCLUSIONS
  This is the first reported case of bone infarction following TPLO in the dog. Bone infarction should be considered as an unlikely but potential complication of TPLO.
