Double dorsal locking compression plate fixation for canine pancarpal arthrodesis: clinical outcomes and complications in 6 dogs.

Abstract

OBJECTIVE: To evaluate clinical outcomes, radiographic healing, and complication rates associated with a double dorsal plating technique for pancarpal arthrodesis in canine patients. ANIMALS: 6 dogs with carpal injuries were presented to a private veterinary referral center, between 2020 and 2024. CLINICAL PRESENTATION: Clinical signs at presentation included lameness (mild to non-weight bearing), carpal instability, pain on manipulation, and swelling. RESULTS: The dogs in the study were medium to large breeds, with a median age of 59 months (range, 35 to 85 months) and a median body weight of 21.7 kg (range, 17.0 to 27.6 kg). Complete radiographic union, defined as > 50% osseous bridging across arthrodesis sites, was achieved in all cases at a median time of 6.5 weeks (range, 5.9 to 7.3 weeks). Two of six dogs experienced complications, consisting of 1 major complication and 1 minor complication. No implant failures or surgical site infections were documented during the study period. Long-term follow-up assessment based on validated owner-reported outcome measures performed at a median of 39 months (range, 12 to 52 months) from surgery demonstrated excellent functional outcomes with minimal chronic pain scores for all cases. CLINICAL RELEVANCE: The double dorsal plating technique represents a viable alternative approach for pancarpal arthrodesis in medium-sized dogs, demonstrating reliable osseous union with acceptable morbidity. This methodology offers enhanced surgical flexibility in implant selection and may be particularly advantageous in cases where metacarpal bone dimensions preclude the use of traditional single-plate constructs with appropriately sized screws. Further prospective studies with larger cohorts are warranted to validate these preliminary findings.
