Technic. The partsare first thoroughly cleansed and any callous around theedges of the fissure is carefully and completely is an essential procedure, for no lateral granulationwill take place, nor can direct apposition be obtained if thiscallous be allowed to remain. Small particles of material from the hosiery or otherforeign bodies should also be thoroughly removed. The. FISSURED TOE WEB 250 PODIATRY recesses of a deep fissure present excellent places of lodg-ment for minute particles which are always to be foundin footgear, and it is these bodies which produce infectiveprocesses. The above precautions having been observed,alcohol, 60%, should be freely applied and the parts thor-oughly dried. Silver nitrate may then be painted deep downinto the floor of the fissure, by means of a cotton-woundapplicator. This will produce some smarting, but it is trans-sient and there will be no great amount of irritation. Thesilver solution should also be applied to the surfaces adja-cent to the edges of the fissure, for it must be rememberedthat silver nitrate is sedative and this action is desirable inreducing the local inflammation. Where the fissure is deep and of long standing, it maybe found necessary to resort to a 25% or 50% solution oreven to the fused stick.
