A new concept for measuring leg length discrepancy [PDF]

Journal of Orthopaedics, 2017
Leg length discrepancy (LLD) has been a controversial issue among researchers and clinicians for many years. Its presence obviously is not in doubt, however, there is little consensus as to its many aspects, including the extent of LLD considered to be clinically significant, the prevalence, reliability and validity of the measuring methods, the effect
