Tarsal Arthrodesis is a surgical elimination of joint motion and, ultimately, bony fusion of joint surfaces. Tarsal arthrodesis is considered a salvage procedure for patients in which other surgical or medical treatment will not restore normal, pain-free joint function. It can relieve pain and restore reasonable limb function.

Surgical Procedure Options for Tarsal Arthrodesis:
“Pantarsal arthrodesis is used to treat talocrural pathology or irreparable injuries to the entire hock joint.”
Partial tarsal arthrodesis seems to be preferable to a pantarsal arthrodesis because motion and function of the unaffected to joints can be preserved. It is the method of choice for fusion of the intertarsal or tarsometatarsal joints.
“Partial tarsal arthrodesis is used to treat luxations or subluxations of the intertarsal and/or tarsometatarsal joints.”
“Autogenous or Allogenous cancellous bone graft is used to encourage early bone healing.”
“The recommended angle of tarsal arthrodesis approximates 135-145° for dogs and 115-125° for cats.”
“ Plates and screws have proven very successful for pantarsal arthrodesis.”
“Incorporation of the calcaneus with at least two screws in the fixation is important to achieve complete and pain-free fustion of all joint levels.”
