Percutaneous epiphysiodesis is a safe technique for correcting leg length discrepancy. While effective for many, precise timing remains crucial to avoid poor outcomes.

Area of Science:

  • Orthopedic surgery
  • Pediatric orthopedics
  • Skeletal growth modulation

Background:

  • Leg length discrepancy (LLD) is a common orthopedic condition in children.
  • Surgical intervention is often required to correct significant LLD.
  • Percutaneous epiphysiodesis offers a minimally invasive approach to growth modulation.

Purpose of the Study:

  • To evaluate the outcomes of percutaneous epiphysiodesis for LLD.
  • To assess the safety and reliability of the procedure.
  • To identify factors contributing to treatment failure.

Main Methods:

  • Retrospective review of 57 patients undergoing percutaneous epiphysiodesis.
  • Analysis of final leg length discrepancy and complication rates.
  • Comparison of failure causes with previous studies.

Main Results:

  • Good results (<1.5 cm LLD) achieved in 68.5% of patients.
  • Fair (1.5-2 cm LLD) and poor (>2 cm LLD) results in 14% and 17.5%, respectively.
  • The technique demonstrated high safety and reliability with minimal technical errors.

Conclusions:

  • Percutaneous epiphysiodesis is a safe and reliable method for correcting leg length discrepancy.
  • Timing errors were identified as the primary cause of suboptimal outcomes.
  • Further refinement in surgical timing can improve treatment efficacy.
