Ulnocarpal arthrodesis in a cat.

Abstract

A nine-year-old cat was presented with non-weight-bearing lameness of the right forelimb subsequent to an old fracture of the antebrachium previously treated by external stabilisation. Radiography showed severe atrophic non-union of the distal third of the radius and carpal luxation. Ulnocarpal arthrodesis was performed using a uniplanar external fixator. Follow-up radiography showed that bone fusion was slow but without complication. After 16 weeks, the external fixator was removed, and a Robert-Jones bandage was applied for one month. From postoperative week 2 onwards, the animal progressively made use of the limb in a weight-bearing capacity. At the last examination, one year postoperative, no lameness was observed.
