Cozen's phenomenon : state-of-the-art management taking the advantages of recent advances in growth modulation with critical review'

Abstract

Cozen’s phenomenon is an uncommon condition with an unclear protocol for management. The purpose of this study was to emphasize a reliable plan for the treatment of these cases. Case series of 14 patients fulfilling the determined inclusion criteria were treated using 8-plate hemiepiphyseodesis. Their mean age at the time of the operation was (4 y & 7m). The mean preoperative anatomical femoro-tibial valgus angle was 22°. Overcorrection (~ 5°) was obtained in all the cases at the end of treatment after a mean period of 15 months. Although two cases showed early rebound at the 8th month of follow up, it was temporary and all the cases fortunately after a mean follow up period of 28 months showed complete resolution. 8-plate is a simple, effective, and safe technique that works successfully when used properly in selected cases of Cozen’s phenomenon.
