TLSO
Also written as: TLSO — Thoracolumbosacral Orthosis
Abbreviation for Thoracolumbosacral Orthosis; a rigid or semi-rigid external spinal brace extending from the thoracic spine to the sacrum, used for immobilisation and support.
Full Definition
A TLSO (Thoracolumbosacral Orthosis) is a type of spinal orthosis commonly prescribed in PM&R settings following thoracic or lumbar vertebral fractures, post-spinal fusion surgery, or for scoliosis management. It encompasses the thoracic, lumbar, and sacral regions of the spine, providing varying degrees of immobilisation depending on the rigidity of the device. Editors should note that TLSO is always written in full capitals without periods and should be expanded on first use in formal reports. Related abbreviations include LSO (Lumbosacral Orthosis), CTLSO (Cervicothoracolumbosacral Orthosis), and CO (Cervical Orthosis); editors must verify the correct level of coverage documented.
Usage
Usage note: Always expand TLSO on first use. Do not confuse with LSO (Lumbosacral Orthosis), which does not extend into the thoracic region.
