spinal orthosis
Pronunciation: spy-nal or-THOH-sis (pl. or-THOH-seez)
An external brace or support device applied to the trunk or spine to immobilise, correct, or support spinal structures during rehabilitation.
Full Definition
A spinal orthosis is a prescribed external device that encompasses part or all of the spinal column, used to limit motion, provide structural support, reduce pain, or facilitate healing following injury, surgery, or in the context of chronic conditions such as scoliosis. Types encountered in rehabilitation documentation include cervical collars, thoracolumbosacral orthoses (TLSOs), and lumbosacral orthoses (LSOs). Editors should be alert to the correct plural ('orthoses', not 'orthosises') and distinguish the term from 'prosthesis', which replaces a missing body part rather than supporting an existing one. The field of spinal orthosis prescription belongs to orthotics and prosthetics (O&P) practice.
Usage
Usage note: Plural is 'orthoses'. Never write 'orthosises'. Distinguish carefully from 'prosthesis/prostheses'.
