ACUTE INFLAMMATION OF THE PODOPHYLLOUS MEMBRANE. 
771 
Purulent cellulitis can, of course, only occur where inflammation seizes 
on sensitive structures possessing a subcutis, like the posterior sections 
Fig. 288.—To illustrate the superficial structures 
involved in surgical injuries of the foot. The 
outer lateral cartilage and the tissues covering 
the lower surface of the pedal hone (sensitive 
frog and sensitive sole) have been removed. 
Plantar cushion ; a', bulbar portion of 
plantar cushion ; a ", cleft of the frog in 
which rests the “ frog stay ” ; b, origin of the 
so-called ‘ £ suspensory ligament of the bulbs ” ; 
b', small elastic band passing towards the 
lateral cartilage ; c, elastic band arising from 
lateral cartilage and becoming inserted into 
pastern bone — it unites with b ; d, small 
tendon which arises from the skin and be¬ 
comes attached, in common with b and c, to 
the pastern bone ; e, fibro-elastic supporting 
sheath of flexor pedis perforans;/, fibro-elastic 
supporting sheath of flexor pedis perforatus ; 
g, flexor pedis perforatus tendon; h, flexor pedis 
perforans tendon ; i, suspensory ligament ; 
k, lower surface of pedal bone, to which the 
flexor pedis perforans tendon is attached.

seated structures involved in 
surgical injuries of the foot. 
Right fore foot seen from behind 
and slightly from one side. 
a, Flexor pedis perforatus ten¬ 
don ; b, two limbs formed by its 
bifurcation ; c, flexor pedis per¬ 
forans tendon ; d, fibrous re¬ 
inforcing band of great sesamoid 
sheath ; cl', fibrous supporting 
sheath inserted into suflraginis 
bone by four heads ; cl", upper 
insertions (the lower not visible 
in figure) ; e, fibro-elastic plate 
covering the lower surface of 
flexor pedis perforans and inserted 
into sutt'raginis bone at e! ; 
/, suspensory ligament.
