*Locate the accessory carpal bone and compare its mobility with the carpal joint flexed and extended. With the joint extended, feel the tension in the tendon attaching to it proximally, (m ulnaris lateralis) and the ligament attaching to it distally (accessoriometacarpal ligament). These are part of the mechanism preventing overextension (dorsal flexion) of the carpus and enabling the dog to be digitigrade. | *Locate the accessory carpal bone and compare its mobility with the carpal joint flexed and extended.
