Minimally invasive repair of central tarsal bone luxation in a dog

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.
