Aspen Horizon PRO 456 TLSO Back Brace

$516.00

The Aspen® Horizon™ PRO 456 TLSO is the thoracolumbar model in Aspen's Horizon PRO line — an inelastic brace, meaning the shell does not stretch as you move, so the compression you set is the compression you keep.

A belt at the waist carries an upright back panel and a yoke across the top of the back, held by shoulder straps and a chest buckle. The yoke height adjusts so it can be set to sit at C7, the bony bump at the base of the neck. The belt covers four sizing positions from one brace, and the two pull tabs tighten the lower and upper halves separately.

It is the brace people are usually stepped down to from a Horizon 456 as recovery moves from protection towards pain management.

Is this the right one for you?

Choose this if you need your spine actively straightened rather than just supported — for osteoporosis, a spinal fracture, a rounded upper back, or scoliosis.

Everyday muscular back pain? Aspen Horizon 637 LSO Back Brace is a lighter brace for strain and fatigue.

This is a medical-grade orthopaedic brace that incorporates rigid structural support. Braces and orthoses built with rigid components are usually covered under Canadian extended health benefit plans (e.g. Sun Life, Manulife, Canada Life, Blue Cross, Green Shield Canada) when accompanied by a valid prescription from your physician or nurse practitioner. It may also qualify as an eligible medical expense under the CRA's Medical Expense Tax Credit. We're happy to prepare an itemized estimate for your insurer — use Get an Insurance Estimate for this item, or add several to your cart and request one for everything at once. No charge, and it's not an order. Coverage details, annual limits, and prescription requirements vary by plan, so please confirm your specific benefits with your provider and keep your prescription and itemized receipt for your claim.

Measure standing upright, breathing out gently, with the tape snug but not pulled tight.

Aspen prints these steps; the first fitting of a post-surgical brace should be supervised by your clinician.

Set the size first: peel up the inside end of each side panel, adjust until the brace closes properly, and press it back down. Aspen's sizes follow standard trouser sizing closely and are guidelines only.
Place the pull tabs about 2 inches (5 cm) from the plastic at the back, then pull the ends apart so the brace is fully extended.
Put the brace on with the back panel centred and low on the back, and wrap it firmly around the abdomen with the right side overlapping the left.
Both the top and bottom edges should feel snug. If either gapes, take it off and reapply, angling the ends until both edges sit close.
Slip each thumb into the pull tabs, extend them out and away from the brace, and press the hook side onto the loop material when the compression is right.
Set the vertical height with the posterior adjustment panel so the yoke rests at C7 — the bony bump you can feel at the base of the neck.
Pull and tighten the shoulder straps, then fasten and tighten the chest buckle to draw the straps away from the armpits.
After the first fitting, sit down, stand up again, and re-adjust — the fit changes between the two.
