ABSTRACT:
The present invention provides an external skeletal fixator for treating an injured mammalian limb. The fixator has a plurality of transfixation pins which pass through the intact bone of the injured limb proximal to the injured bone. These pins extend beyond the outer edges of the intact bone. These pins are supported by support members which abut the intact bone, extending through the soft tissue. These support members are, in turn, supported by a superstructure capable of supporting the weight of the animal, which superstructure extends beyond the distal end of the injured limb. Thus in the case of a weight bearing limb, the weight of the animal is transferred from the intact bone to the pins, to the supporting members, to the superstructure, to the ground, thus bypassing the injured bone.
