The limb appears shorter than its neighbour when the animal stands on it, and the prominence representing the trochanter is more marked. When a false joint has formed, the limb is rigid, is moved stiffly and abducted, and the stride is shortened. In accidental luxations, either of one or both limbs, the attitude assumed by the animal is often characteristic.

In accidental luxations, either of one or both limbs, the attitude assumed by the animal is often characteristic. One of the limbs is ex- tended at right angles to the longitudinal axis of the body, and some- times both limbs assume this position, an attitude which would be absolutely impossible under normal conditions. The animal cannot rise. It lifts the front part of the body by rising on its knees, but the hind quarters do not follow. The ruptured adductor muscles are unable to bring and hold the limb parallel to the longitudinal axis of the body; the abductors act unopposed, and at the moment wdien the animal makes
