Gangraena humida pedis - wet gangrene of the foot
Though it can form from any occlusion of blood supply, this gangrenous foot has a particularly interesting origin.
Following the forcible correction of a flexion contracture due to tuberculosis of the hip-joint, the toes became flexed, cold, and blue. Shortly thereafter, the toes blackened, and fistulae formed on the first and fifth toes, where necrotic bone began to protrude.
As the gangrenous tissue only formed on the end of the foot, it is obvious that there was no full occlusion or rupture of the femoral artery. The physician surmised that the pinched intima of the artery caused thrombosis of a vessel in the foot, and the tissue beyond that point died.
This case only required the amputation of the anterior portion of the foot and recovered easily.
