Fractures of the proximal tibial epiphysis are rare. A series of
twenty-eight fractures classified according to the Salter-Harris method
showed that nine were Type II and eight, Type IV. Lawn-mower injuries, a
previously unreported mode of injury for this fracture, caused five of the
eight Type-IV fractures and were associated with the worst prognosis by
far. Two Type-V fractures in the proximal tibial epiphysis, previously
unreported, are described.
