With the descent of the os pedis we get in many cases a penetration of the horny sole (see Fig. 117), leading always to serious displacement of the sensitive sole (see Fig. 117, b), and often to caries of the exposed bone. The backward displacement of the os pedis may be accounted for in two ways. Firstly, the greater

The backward displacement of the os pedis may be accounted for in two ways. Firstly, the greater vascularity of the membrane covering its front leads to a greater out- pouring of inflammatory fluid in that particular position. Flere, therefore, loss of adhesion with the wall is greatest, while into the cavity so formed is poured a large quantity
