Elkoplasty, or anaplasty applied to the treatment of old ulcers.

Hamilton was among the first to treat ulcers by skin-grafting. He made the flap smaller than the space which it was intended to fill, “trusting to growth and expansion of the graft to complete the cure”. Also published in N. Y. J. Med., 1854, 13, 163-73. See his earlier theoretical paper in Buffalo med. J., 1847, 2, 501-509.
