Leg Retained at the Elbow.

Leg Retained at the Elbow.
The lamb is in anterior presentation, in a dorso-sacral position, with abnormal posture. Both legs are retained at the elbow. The lamb may need to be repelled into the uterus to permit extension of the front legs, but often traction on just one leg at a time will correct the "elbow lock".
