Abbreviation for Limb-Length Discrepancy; a measurable inequality between paired limbs requiring orthotic or surgical correction.
Full Definition
LLD is the standard abbreviation in orthotics and rehabilitation documentation for limb-length discrepancy. It appears in referral letters, fabrication orders, insurance pre-authorisation requests, and outcome measurement tools. Editors must confirm at first use that LLD is expanded, particularly in documents intended for multidisciplinary or lay audiences. The abbreviation should not be confused with other medical abbreviations sharing the same initialism.
Usage
Usage note: Always expand at first use in documents targeting a non-specialist or multidisciplinary readership.
