Limb length discrepancy.

The surgical management of LLD has gradually evolved from a time when patients were bedridden in traction for prolong periods of time to the point at which much of the treatment time is spent in mobility. Improved surgical techniques, such as percutaneous epiphysiodesis and distraction osteogenesis, have contributed greatly to the success of surgery for LLD. Factors affecting outcome and patient satisfaction must be weighed carefully before selecting treatment for LLD.
