How to Wear and Care for a Thoracolumbosacral Orthosis (TLSO) Brace

Published: October 19, 2026Updated: October 19, 2026

A thoracic-lumbar-sacral orthosis (TLSO) immobilizes the thoracic and lumbar spine to promote fracture healing or prevent scoliosis progression. Correctly putting on, adjusting, and maintaining your brace ensures proper spinal alignment while protecting your skin from pressure injuries. Follow this clinical guide to safely manage your daily bracing routine as directed by your care team.

Quick Summary

Wear a seamless cotton undershirt, align the brace precisely above your hip bones without twisting your spine, tighten straps to prescribed markers, and inspect skin daily.

Step-by-Step Guide

Apply a Clean, Seamless Undergarment

Before putting on the orthosis, put on a clean, 100% cotton, seamless t-shirt or designated orthotic body sock. Smooth out all wrinkles, folds, and bunched fabric across your torso, chest, and hips. The fabric layer wicks perspiration, minimizes friction, and protects fragile skin from direct contact with hard plastic and foam pads.

Important: Never wear the brace directly against bare skin or over garments with thick seams, zippers, or buttons, as these cause localized skin breakdown.

Position Yourself Using Prescribed Precautions

Position your body according to your physician's specific protocol. For acute spinal fractures, apply the brace while lying completely flat on a firm mattress using the 'log-roll' technique to keep your head, shoulders, and hips moving together as one rigid unit. For adolescent idiopathic scoliosis, you may generally stand or sit as directed by your orthotist to position the posterior shell.

Important: If you are recovering from a spinal fracture, do not bend, twist, or arch your back while getting into position.

Align the Waist Indentations on the Iliac Crests

Place the posterior shell behind your back and slide the anterior shell into place over your chest and abdomen. Locate the waist grooves (waist indentations) built into the interior foam of the brace and confirm they rest directly over your waist, immediately above your iliac crests (top edges of your hip bones). Correct vertical alignment ensures proper weight distribution and prevents the brace from riding up or shifting downward.

Fasten and Fast-Check Straps in Sequence

Secure the hook-and-loop closure straps beginning at the middle or lower section over the hips to lock the pelvis into position, then move upward to the chest straps. Pull the straps firmly to the pencil or notch lines marked by your orthotist during your fitting. The brace must fit snugly enough that you cannot slide a flat hand between the orthosis and your torso during regular breathing.

Important: Wearing the brace too loosely allows friction and migration, significantly reducing spinal stabilization and increasing shear forces on the skin.

Perform a Daily Two-Point Skin Inspection

Each time the brace is removed for permitted hygiene or rest intervals, thoroughly inspect your skin using a handheld mirror or assistance from a caregiver. Pay close attention to bony prominences including your hip crests, spine, lower ribs, and underarm margins. Mild pinkness that fades completely within 30 minutes of brace removal is normal adaptation to pressure.

Important: If redness does not fade within 30 minutes, or if you detect blisters, bruising, or open sores, keep the brace off and contact your orthotist immediately.

Clean and Maintain the Orthosis Daily

Clean the hard plastic exterior and inner closed-cell foam liner daily using a washcloth dampened with mild hypoallergenic soap and warm water. Wipe thoroughly with a second damp cloth to remove any residual soap that could irritate your skin. Dry the brace completely with a towel and allow it to air-dry away from direct heat sources such as radiators, hair dryers, or direct sunlight before putting it back on.

Important: Do not submerge the brace in water or expose it to high heat, which can warp the rigid thermoplastic and destroy the structural integrity.

Frequently Asked Questions

Can I sleep in my TLSO brace?

This depends entirely on your diagnosis. Patients treated for spinal fractures typically must wear the brace 24 hours a day, including while sleeping, removing it only under medical supervision. Scoliosis nighttime braces are designed specifically for sleeping, whereas standard scoliosis braces may require 16 to 23 hours of wear per day as prescribed by your orthopedist.

How do I take a shower while wearing a TLSO?

If you have an unstable spine fracture, your surgeon will determine if you must shower wearing a secondary waterproof brace, take sponge baths in bed, or briefly remove the brace while standing entirely upright without bending. Never remove your brace to shower unless your physician has explicitly cleared you to do so.

Why does my brace feel tighter after eating meals?

Abdominal expansion during and after meals pushes against the anterior shell of the brace. Eating smaller, more frequent meals throughout the day reduces discomfort. Do not loosen the straps past your orthotist's designated alignment marks without consulting your care team, as doing so compromises spinal support.

What should I do if the brace is rubbing against my hip bones?

Check that the internal waist grooves are positioned precisely above your iliac crests, as slippage is the most common cause of hip pressure. If the brace is properly aligned but still pinches or causes persistent pain, schedule an adjustment appointment with your orthotist; do not attempt to trim or bend the plastic yourself.
