An 18-month-old miniature donkey was presented for evaluation and treatment of a
left carpal valgus present since birth. Clinical examination confirmed the severe and
unstable carpal valgus. Radiographs and computed tomography revealed a caudally
luxated ulnar carpal bone, malformation of the distal radial epiphysis, as well as a
complete collapse of the lateral part of the radiocarpal joint. Outward rotation of the
limb distal to the joint collapse was also visible. Surgical treatment was elected and a
pancarpal arthrodesis performed using two short 3.5 mm locking compression plates.
Ten months later, the donkey was pasture sound and radiographs showed complete
fusion of the carpal joints.
