Angiomicrographic investigation of the vessels associated with physes in young pigs.
There is little information available relating to the vasculature of physes of pigs, hence the object of the present study was to establish the distribution of blood vessels in normal physes of pigs at one and 15 days old. By the use of an angiomicrographic technique it was possible to demonstrate that vessels were in two main categories; first, those which entered the physis from the epiphysis and terminated, or branched and then terminated half to two thirds of the distance into the depth of the physis; second, vessels which crossed the full depth of the physis. Since vessels that cross the physis from epiphysis to metaphysis were a frequent feature of normal physes they do not seem to be a congenital defect which predisposes to the development of dyschondroplasias in young pigs.
