Outcome, Complications, and Follow-Up in Dogs Treated with Pancarpal Arthrodesis Stabilized with Orthogonal Plates.

Pancarpal arthrodesis was performed in 21 dogs, using orthogonal (cranial/dorsal and medial) plates without postoperative rigid external coaptation. Short-term and long-term outcomes, arthrodesis progression, and complications were assessed using a retrospective review of case records and radiographs. Three of 21 (14.2%) dogs required a revision surgery: 2 had total implant explantation and 1 had a screw removed. Other complications were managed successfully medically. One of 21 (4.8%) dogs had confirmed deep surgical site infection requiring implant removal, and 4 of 21 (19%) had suspected (not confirmed on microbiology) superficial surgical site infections that resolved with medical management. Long-term outcomes were assessed via owner questionnaire (Canine Brief Pain Inventory) and were available for nine dogs at a mean of 26.78 mo after surgery. The mean score for the first part (assessment of pain) was 7.83/40, which is classified as no pain to mild pain. The mean score for the second part (assessment of function) was 12.67/60, which is classified as very good. The last part (overall impression) was defined as excellent in four dogs (44.44%), very good in one dog (11.11%), and good in the other four dogs (44.44%). This retrospective study documents a suitable technique for pancarpal arthrodesis in dogs with carpal injuries.
