The anaesthesic blocks are important in the diagnose of lameness in equines, and an alternative to anaesthesias in several procedures. In this experiment, nine crossbred equines were utilized. It was given 3ml lipoidol 50% in the navicular bone synovial bursa in all animals, with the purpose of evaluating the existence of communication between the navicular bone synovial bursa and distal interphalangeal joint. In 33,3% of the cases it was observed contrast in the dorsal region of the distal interphalangeal joint after its administration in the synovial bursa of the navicular bone. The communication occured only in the adult animals.
