Summary
Objectives: To describe the use of closed reduction and minimally invasive fixation for treatment
of a central tarsal bone luxation in a six-year-old spayed female, mixed breed dog
with acute onset non-weight bearing right hindlimb lameness.
Methods: Physical examination and tarsal radiographs resulted in a diagnosis of central tarsal
bone luxation. Closed reduction and minimally invasive screw stabilization were performed
with fluoroscopic guidance. External coaptation for six weeks was followed by a gradual
return to full function.
Results: Follow-up examination at 34 months post-surgery revealed the patient to be fully
functional on the surgically repaired limb. Radiographs revealed ankylosis of the
intertarsal joints.
Clinical significance: Minimally invasive ankle surgery is commonly performed in humans but is uncommon
in dogs. Based on the results of this single case, minimally invasive reduction and
stabilization of central tarsal bone luxation is feasible.
