OBJECTIVE: To report the surgical technique, complications, and outcomes of 8 dogs that underwent a unilateral pantarsal arthrodesis stabilized using a circular external skeletal fixator (CESF) construct for the treatment of uni- or multilevel tarsal instability.
ANIMALS: 8 dogs.
CLINICAL PRESENTATION: Medical records from 2010 to 2023 from 2 small animal hospitals were retrospectively reviewed for dogs undergoing pantarsal arthrodeses stabilized with CESF. Data collected for each dog included signalment, injury etiology, construct configuration, radiographic imaging, antimicrobial use, complications, length of time until construct removal, and outcome based on clinical evaluation by the owner and veterinary surgeon.
RESULTS: 8 dogs met the requirements of inclusion for the study. Dogs had a mean age of 5.5 years (range, 0.42 to 13 years) and weight of 15.1 kg (range, 2.5 to 26.4 kg). Angulated 3- and 4-ring constructs were used in 5 and 3 dogs, respectively, with or without hybridization. Tarsi were stabilized with a mean angle of extension of 124.8° (range, 111.5° to 136.5°). Fixator removal was performed at a mean time of 11.3 weeks (range, 6 to 16 weeks). Complications developed in 4 dogs, 2 of which had poor clinical outcomes despite additional interventions, including recurrent digit trauma and poor limb use postoperatively. Six dogs had excellent outcomes.
CLINICAL RELEVANCE: A CESF may be considered as an alternative to plate stabilization when performing a pantarsal arthrodesis. This fixation requires rigorous postoperative care but obviates the need for supplemental postoperative coaptation.
