Aegineta Paulus, The seven books of Paulus Ægineta… (1844)
“ When, therefore, the sinus extends upwards, the ichor readily flows out from the sore, and adhesion easily takes place; but when it extends downwards the ichor by remaining within corrodes the continuous parts, and unless you first make an incision for its discharge, you will be able to effect nothing; for the sores can neither be incarnated nor the parts made to unite. But if the sinus is in any of the limbs, as the arms or legs, one may produce adhesion without a counter-division by putting the limb in a declining position. ”
