Journal of Pediatric Orthopaedics B: January 2003 - Volume 12 - Issue 1 - p 69-71 Buy Abstract This study presents a retrospective evaluation of 57 patients who underwent a percutaneous epiphysiodesis for leg length discrepancy. Of these patients, 68.5% presented with a good result with a final leg length discrepancy of less than 1.5 cm, 14% with a fair result with a discrepancy of between 1.5 and 2 cm, and 17.5% showed a poor result with a leg length discrepancy of more than 2 cm. The percutaneous epiphysiodesis was found to be a safe and reliable technique. There were very few technical errors. The causes of failure were analyzed and compared with a previous study from the same department. Error in timing remains the main problem. © 2003 Lippincott Williams & Wilkins, Inc.
