Centrodistal joint lameness in dogs.

Abstract

Lameness attributable to pathology of the centrodistal joint was investigated in five racing greyhounds, five Border collies and two other dogs. Diagnosis was made by the induction of pain from rotationally stressing the medial aspect of the tarsus, and by the exclusion of tarsal fractures and instabilities. Radiographic changes included plantar ligament entheslopathy and centrodistal joint osteophytosis. In many of the cases, the lameness was poorly responsive to rest and non-steroidal anti-inflammatory drugs. One dog was managed conservatively and became sound. In 10 of 11 cases, surgical promotion of centrodistal ankylosis was associated with a return to soundness.
