Spinal Orthosis
Pronunciation: SPY-nul or-THOH-sis
An external device applied to the trunk to immobilise, support, correct, or offload segments of the spinal column during rehabilitation or recovery.
Full Definition
Spinal orthoses are a subcategory of orthotic devices prescribed in PM&R for conditions including vertebral fractures, post-surgical stabilisation, scoliosis, and cervical spine injuries. Common types include cervical collars, thoracolumbosacral orthoses (TLSOs), lumbosacral orthoses (LSOs), and halo vests. In clinical documentation, editors should confirm that the specific device type is named rather than only the generic term 'spinal orthosis,' as different devices carry distinct prescription, billing, and functional implications. The plural is 'spinal orthoses' (not 'orthosises'). Note that 'orthosis' and 'orthotic' are not interchangeable: 'orthosis' is the device; 'orthotic' is the adjective (though 'orthotics' as a noun refers to the clinical field or a set of devices).
Usage
Usage note: Use the plural 'orthoses,' never 'orthosises.' Distinguish 'orthosis' (the device) from 'orthotic' (adjective or field). Always specify device type in clinical documentation.
