Fractures of the proximal humeral epiphysis.

Twenty-two patients with marked displacement of a fracture of the proximal humeral epiphysis have been treated with closed or open reduction and fixation by Kirschner wires. At an average follow-up of 6.8 years there have been good functional results in almost all patients (91.1), with better results in patients under 13 years of age particularly with less residual displacement or angulation. Since there is a greater occurrence of residual deformity and symmetria and limitation of motion in older patients, a more aggressive approach to correct the initial displacement and angulation is warranted in those over the age of 13 years.
