up, on the lateral side, a depression where the fibula is broken. The need of replacing thesfoot 

 and the weight-bearing talus (astragalus) accurately, the fact that the ankle-joint is opened and 

 the numerous tendons likely to be matted are the chief points to bear in mind. In Dupuytren's 

 fracture there is not only fracture of the lower end of the fibula, but the inferior tibio-fibular 

 ligaments are now torn. The foot is displaced upward and laterally, together with the lower

end of the fibula. Epiphyses. — The upper one of the tibia appears shortly before birth and 

 includes the condyle and tuberosity. It does not fuse with the shaft till the age of twenty or 

 later. This fact and the powerful strain of the rectus on this epiphysis explain the obscure 

 pain sometimes complained of in young adults much given to athletics, over the tibial tuberosity. 

 The lower epiphysis, including the medial malleolus, appears in the second and joins about the 

 eighteenth year. Separation here is not very uncommon up to puberty. In osteotomy of the
