-----A common antler deformity results from damage to a deer’s front or rear leg. Rear leg injuries produce a “contralateral” antler deformity (malformed antler on the opposite side from the injury), possibly due to one side of the brain controlling the opposite side of the body. After a very serious leg injury, a buck may never produce a quality rack. Injury to a front leg may produce a malformed antler on either, both, or neither sides. Body injuries may or may not cause antler abnormalities.------
