Background: Trauma to the canine foot may result in injury to soft tissue or bone or both. Foot injury often results in fractures and joint instability because of disruption to carpal or tarsal ligaments. Several fi xation methods have been described for stabilizing tarsometatarsal arthrodesis. The aim of this paper is to report the case of a unilateral tarsometatarsal arthrodesis with use of circular skeletal fi xator on the left pelvic limb of a dog.Case: A 5-year-old intact male dog weighting 25 kg was referred to the veterinary hospital with a left tarsal degloving injury. The previous history revealed that the dog had been bitten by another dog seven days prior to the referral. On physical exam it had swelling and severe pain on the left foot, crepitus of the intertarsal/tarsometatarsal region, instability, bone exposure and myiasis larvae on the wound. The dog was non-weight-bearing on the affected limb. No other abnormalities were found. Radiographs revealed it to be an open fracture of the left tarsal distal line with tarsometatarsal luxation. Adherent dressings were changed for seven days to minimize the contamination before surgery. The dog was treated by open reduction and internal fixation using a circular skeletal fixator. After general anesthesia was induced, a lateral approach to the tarsometatarsal joint was made. The tarsometatarsal joint then was exposed. Arti
