Epiphysiodesis of the lower extremity: results of the percutaneous technique.

The results of 42 percutaneous epiphysiodeses of the lower extremity in 26 patients are reported. All patients achieved physeal arrest radiographically and clinically. No patient developed angular deformity from incomplete arrest. No neurovascular complications or fractures occurred. The average hospital stay for patients undergoing epiphysiodesis alone was 1 day. Percutaneous epiphysiodesis of the lower extremity provides a reliable and safe technique for growth plate arrest. The advantages of this technique include a cosmetic scar, short hospital stay, low incidence of complications, and reliable physeal arrest.
