Summary

A twenty-eight-month old female spayed American Bulldog was presented for evaluation of a chronic draining tract and intermittent left hindlimb lameness twenty-eight weeks after a combination tibial plateau levelling osteotomy and cranial closing wedge osteotomy (TLPO/CCWO) had been performed. The patient had developed an infection of the surgical site three weeks postoperatively. Drainage persisted despite implant removal 10 weeks postoperatively and several weeks of culture and sensitivity-directed antibiotic therapy. Twenty-eight weeks postoperatively, a sequestrum was identified on radiographs. Surgical removal of the sequestrum resulted in resolution of the drainage. While osteomyelitis is a known complication of TPLO surgery, this case represents the first described case of osteomyelitis-related sequestrum formation in association with the combined TPLO/CCWO procedure
