hemiepiphysiodesis
Pronunciation: HEM-ee-ep-ih-FIZ-ee-oh-DEE-sis
Surgical arrest of growth on one side of a growth plate to correct angular deformities by allowing continued growth on the opposite side.
Full Definition
Hemiepiphysiodesis is a surgical procedure that selectively arrests growth on one side of a growth plate while preserving growth on the opposite side, allowing for gradual correction of angular deformities in growing children. The technique can be performed using various methods including stapling, tension band plating (eight-plates), or permanent physeal bar creation. The goal is to utilize the remaining growth potential to achieve correction while avoiding the need for corrective osteotomy. Success depends on adequate remaining growth, appropriate timing, and careful patient selection. The procedure is reversible when temporary implants are used.
