Lateral ligamentous injury to the carpus of a racing greyhound.

The lateral collateral ligament of the ulna and the dorsolateral ligaments of the radiocarpal joint of a racing Greyhound were ruptured, resulting in instability of the carpus when the joint was flexed. This report describes a technique for making a ligament prosthesis, using the ulnaris lateralis tendon. Although the dog did not return to racing, the carpus was stable enough for general activity.
