Percutaneous vs modified phemister epiphysiodesis of the lower extremity.

Abstract

Epiphysiodesis of the lower extremity for limb-length discrepancy has been performed on 24 patients by both the modified Phemister and a percutaneous method. The primary complication of epiphysiodesis by both methods was continued growth of the physeal plate (12% and 15%, respectively). Failure of epiphysiodesis was attributed to young skeletal age at surgery in three of five cases. Closer attention to physeal ablation and close follow up should prevent this complication. No angular deformities resulted in any patient. During 16 proximal fibular procedures, there were no neurologic complications. The percutaneous method is preferred due to ease of surgical procedure, minimal incisions, limited disability to the normal extremity, and equal results.
