Cone epiphysis of the knee and scurvy.

A rare case of metaphyseal cupping of the distal femur resulting from infantile scury in a child is reported. The radiological and surgical aspects of this case are of particular interest. MRI demonstrated central epiphysiodesis of the right knee, surgery achieved rupture of the epiphyseal plate and resulted in femoral lengthening. The child's limp disappeared as a result.
