TALIPES CALCANBO-VALGUS. 155 



of the anterior tibial group, it may be possible to bring a part of 

 the tendon of the active tibialis posticus forwards around the 

 inner side of the tibia, and to graft it into the tendon of the 

 paralysed tibialis anticus. Supposing that the peroneus longus 

 retains its activity, part of its tendon may be carried across the 

 antero-external surface of the leg above the external malleolus, 

 and fixed to some or even all of the tendons of the paralysed 

 extensor group. On the other hand, should the peronei have 

 lost their function, the outer part of the tendo Achillis may be 

 fixed to them. 



Talipes Calcaneo-Yalgus. It is uncommon to get pure talipes 

 calcaneus or pure talipes valgus (if flat-foot is excluded), and not 

 very common even to see the combination of the two. 



The position of the foot in calcaneo- valgus is that the anterior 

 portion of the foot is dorsi-flexed, abducted and somewhat 

 externally rotated. 



In acquired cases from infantile paralysis, the contracted 

 tendons are those of the anterior tibial and peroneal group, 

 particularly the peroneus longus and brevis and the extensor 

 longus digitorum. In the operative treatment by tendon -grafting, 

 a portion of the active tibialis anticus tendon may be grafted 

 into the paralysed tibialis posticus, and the whole of the peroneus 

 longus spliced into the tendo Achillis.
