simple interrupted stitches that do not cross over the wound 

 externally, and the latter differs from the former only in that 

 a button is interposed at each point of entrance. (Figs. 56-57.) 

 These sutures are placed some distance from the borders of 

 the wound, and are supplemented by interrupted or continu- 

 ous sutures which effect the direct apposition of the edges.

 of pressure, — stitch necrosis. No part of the incarcerated 

 tissues is subjected to severe pressure, as in the case of the 

 simple interrupted suture. 



The stitches are inserted as follows: The needle first 

 penetrates from without inward, crosses to the opposite, 

 penetrates from within outward, then is brought back' to the 

 original side some small distance from the first point of 

 entrance and passes through both edges as above. When

 an "X" over the surface. As many of these individual 

 stitches as necessary to close the breach may be consecu- 

 tively "placed, but the greatest value of the method is found 

 in short incisions (plantar neurotomy) where only one is 

 required to close the gap.

 able buried stitches is an entirely new procedure ; it has never
