Magnetic resonance imaging of growth plate injuries: the efficacy and indications for surgical procedures

Abstract

In 23 patients with growth plate injuries, magnetic resonance imaging (MRI) studies were performed a total of 31 times to evaluate the physis which showed plain radiographic evidence of possible damage. Fourteen patients clinically showed growth arrest, and 10 patients required a Langenskiold operation. In 3 patients who underwent this operation, subsequent premature total fusion of the physis adversely affected the postoperative results. We propose that the merging shape of the arrest line with calcification of the provisional zone of the metaphysis shown by MRI indicates poor viability of the physis. MRI provided useful information on the appearance of the growth plate and changes in the metaphysis, both of which affected the prognosis and the results of the surgical procedures.
