What does CTLSO stand for in spinal orthoses?

• A. Cervico-Thoraco-Lumbo-Sacral Orthosis
• B. Cervical Thoracic Lumbar Sacral Orthosis
• C. Upper limb orthosis
• D. Wrist-hand orthosis

Answer: (A)

CTLSO denotes a spinal brace that immobilizes multiple spine segments from the neck down to the sacrum. The term breaks into cervico-, thoraco-, lumbo-, and sacral with orthosis meaning a brace. So it is Cervico-Thoraco-Lumbo-Sacral Orthosis, a device designed to stabilize the cervical, thoracic, lumbar, and sacral regions in one supports. This differs from options that describe only upper-limb devices or use different word forms like cervical or lumbar alone, which don’t convey the full multi-segment coverage of this spinal brace.
