Addendum to all three hypotheses There is a metacarpal fracture in the left front leg most likely due to trauma associated with the use of the FrankÕs calf jack. Crepitation and joint instability are found in the metacarpal region, supporting the presence of a fracture. Furthermore, the left front leg has several surface wounds also associated with the chains used in the FrankÕs calf jack. This applies to all three hypotheses.
