Thoracic-Lumbar-Sacral Orthosis (TLSO) Brace Guide
A thoracic-lumbar-sacral orthosis (TLSO) stabilizes the spine to promote bone healing following a fracture or to halt curve progression in scoliosis. Proper positioning, secure strapping, and consistent skin care are essential for both treatment success and personal comfort. This guide outlines how to safely wear, adjust, inspect, and maintain your TLSO brace.
Quick Summary
Wear a seamless cotton undershirt, align the brace's waist grooves over your hip bones, fasten straps from the middle outward, and inspect your skin daily for irritation.

Step-by-Step Guide
Apply a Protective Base Layer
Put on a clean, snug-fitting, 100% cotton undershirt or dedicated orthotic undershirt beneath the brace. Ensure there are no wrinkles, seams, or folds pressing directly against your skin, particularly along the spine and hips. Keep your skin clean and dry, avoiding creams, powders, or lotions that can trap moisture under the plastic.
Important: Never wear the rigid brace directly against bare skin, as friction and trapped moisture rapidly cause pressure sores and skin tears.
Position the Brace Correctly
Apply the brace either lying down using a log-roll technique or standing straight, strictly adhering to your orthopedic surgeon's instructions. Align the internal waist pads or indentations (waist grooves) precisely over the soft space between your lower ribs and the top of your pelvic bones (iliac crests). Ensure the back panel is centered along the midline of your spine before securing the front shell.
Important: If recovering from an acute spinal fracture, do not twist, bend, or sit up without the brace on; follow strict log-rolling techniques while lying flat to don the device.
Fasten and Tighten Straps Sequentially
Fasten the middle straps first over the waist to lock the brace into the iliac crests, preventing it from migrating upward or downward. Next, tighten the bottom pelvic straps, followed by the top chest straps until snug. Tighten all straps to the lines or pencil marks indicated by your orthotist to ensure clinical efficacy.
Verify Alignment and Comfort in Resting Positions
Check that the brace does not dig into your armpits when your arms are resting naturally, nor into your thighs when sitting upright at a 90-degree angle. Ensure that breathing feels comfortable and that the device does not excessively compress your abdomen. If you notice sharp pinching or severe restriction, loosen the straps slightly and re-align the waist grooves.
Perform Routine Skin Checks
Remove the brace during your scheduled hygiene intervals and inspect your skin thoroughly using a hand mirror or the assistance of a caregiver. Focus attention on bony prominences such as the hip bones, spinal column, shoulder blades, and lower ribs. Mild pinkness that fades within 30 minutes of brace removal is expected, but persistent redness warrants attention.
Important: Contact your orthotist or care team immediately if you develop blistering, open skin breakdown, bruising, or persistent numbness in your legs.
Clean and Maintain the Orthosis Daily
Wipe down the hard plastic exterior shell and inner foam liner daily using a damp cloth moistened with mild antibacterial soap and warm water. Dry the interior completely with a clean towel, or let it air dry in a well-ventilated room away from direct heat. Replace your cotton undershirt at least once daily to maintain optimal hygiene.
Important: Do not submerge the brace in water or use heat sources like hair dryers or radiators, as intense heat will deform the custom-molded plastic.
