a
For ages in age classes, see Table 1
b
One patient had a third fracture in the distal epiphysis of the fibula.
c
One patient had a third fracture in the distal epiphysis of the tibia.
Si: only simple fractures; Mu: at least 1 multifragmentary fracture.
%: proportion of multifragmentary fractures.
E: epiphyseal; M: metaphyseal; D: diaphyseal.
