Atlas of clinical surgery; with special reference to diagnosis and treatment for practitioners and students. nterest, gangrene of thefoot having developed after forcible correction offlexion contracture due to tuberculosis of the hipjoint.

As the gan-grene was limited to the anterior portion of the foot,it is probable that the injury was to the intima onlyand not a complete rupture of the femoral artery,and that gangrene was due to thrombosis of the vessel. The figure shows gangrene gradually involving theanterior part of the foot. In the first and fifth toesnecrotic bone emerges from fistulas in the skin. Inthe sole of the foot a wide zone of demarcation is seen,covered with granulations, and separating the gan-grenous part from the healthy tissues behind. Whenthe line of demarcation has extended all round thefoot, the gangrenous part can be removed, and thewound can be repaired by an osteoplastic different forms of gangrene will be describedwith the next plate. 344 Bockenheimer, Atlas.

The term gangrene is applied to extensive, pro-gressive death of the superficial tissues of the body;the term necrosis to death of the deeper structures(fascia, muscle and bone). The bones have a greaterpower of resistance than the skin, which may becomegangrenous after slight disturbance in the certain conditions, after cutting off theblood supply, the whole peripheral part of a limbmay become destroyed; but, as the death of thetissues is first noticed in the skin, it is spoken of asgangrene. ^Vhen the process consists in desiccationof the tissues it is called dry gangrene; when it endsin liquefaction from the invasion of putrefactive bac-teria, it is called moist or infective gangrene.
