Freezing an extremity in preparation for amputation.

Patients requiring a major amputation for ischemia are frequently gravely ill. Physiologic amputation obtained by freezing the leg, usually with a tourniquet, will permit delay and intensive preoperative therapy. In an efficient, safe, and convenient method which we have developed and used in 46 patients, a pump circulates antifreeze solution through a specially constructed boot.

A technic for freezing an extremity in preparation for amputation.

Freezing of an extremity permits delay in amputation, and the time gained can be devoted to such intensive therapy as may be indicated. A safe, efficient, and convenient technic is described.
