Surgical epiphysiodesis indications and techniques: update.
To present a summary of epiphysiodesis indications and to report most recent advances in the field, along with their clinical relevance. Percutaneous epiphysiodesis using transphyseal screws (PETS) and guided growth using eight plates represent the most recent techniques used for hemiepiphysiodesis. PETS and guided growth have yielded very good results and low rates of complications and are the current standard for the management of angular deformities of the lower extremities in children. Permanent percutaneous epiphysiodesis remains the preferred method for the treatment of limb length discrepancies.
