Shop spinal braces and back supports for the lower and middle back, including rigid LSO (lumbosacral) braces and TLSO (thoracolumbosacral) braces. Compare Ossur Miami LSO, Miami TLSO 456 and 464, Miami Lumbar Posteo, and OAM Rigid Lumbar configurations, plus compatible Miami belt extensions.
Quick selection guide: If the prescription calls for a lower-back orthosis, compare Miami LSO and OAM Rigid Lumbar by their exact panel kits. For prescribed thoracic-plus-lumbar support, compare TLSO 456 (posterior thoracic extension) with TLSO 464 (additional anterior thoracic extension). Miami Lumbar Posteo has a distinct fracture-support design and back-length sizing. These are selection clues, not interchangeable prescriptions.
Before ordering: Rigid spinal braces may be prescribed following injury or surgery. A clinician must identify the correct spinal region, model, rigid panels and fit. Do not select a stronger-looking brace or change the prescribed support configuration without clinical guidance.
Rigid LSO and TLSO Spinal Braces: Shop by Support Design
LSO back braces support the lumbar and sacral regions of the lower back. Some models offer different anterior and posterior support panels. TLSO back braces extend higher to help stabilize the thoracic and lumbar regions when that support is prescribed.
Compare the Five Ossur Spinal-Brace Families
The most important difference is where the rigid support is positioned and which panels or extensions are included. Each product below leads to its own Shopify page, where you select the actual manufacturer configuration.
| Brace | Support design | What makes it different | Shop exact kits |
|---|---|---|---|
|
Miami LSO Lower back |
Lumbar belt with specified rigid panel kit | 626, 627, 631 and 637 options vary the anterior, posterior and lateral panel support. No tall thoracic extension like the Miami TLSO models. | View Miami LSO |
|
Miami TLSO 456 Mid and lower back |
Lumbar support plus posterior thoracic extension and shoulder straps | Supports higher on the back. Uses waist size, belt width and prescribed lordotic or non-lordotic profile where offered. | View TLSO 456 |
|
Miami TLSO 464 Mid and lower back |
Posterior thoracic extension plus adjustable anterior thoracic extension | Has an additional front chest/thoracic support structure and configurable strapping. Not automatically preferable to 456; confirm the prescription. | View TLSO 464 |
|
Miami Lumbar Posteo Thoracolumbar |
Lumbar compression with a contoured posterior thoracic extension and adjustable axillary straps | Designed particularly for clinician-directed support of stable vertebral compression-fracture pain. Select by back length, not the other models' waist charts. | View Posteo |
|
OAM Rigid Lumbar Lower back |
Separate rigid lumbar belt and panel kit family | 627, 631 and 637 kits offer different anterior, posterior and lateral panel arrangements; choose Slim or Standard belt and the matching length/panel options. | View OAM |
Miami TLSO 456 vs. 464: Why the Front Support Matters
Miami TLSO 456: posterior thoracic extension and shoulder-strap support. Miami TLSO 464: includes that posterior support design and adds an adjustable front thoracic/chest extension. This changes the brace architecture, not just its price. A prescribing professional determines whether anterior thoracic support is required; do not substitute one for the other on appearance alone.
Miami LSO vs. OAM Rigid Lumbar: Compare the Actual Kit Components
Both product families offer modular lumbar stabilization, but their belts, panels and kits are not interchangeable. Even when their package numbers look similar, check the listed components for the exact model.
| Kit label | Miami LSO | OAM Rigid Lumbar |
|---|---|---|
| 626 | Standard posterior panel configuration | Not offered in this OrthoTape OAM listing |
| 627 | Anterior plus standard posterior panel | Belt plus anterior panel in the listed OAM 627 kit |
| 631 | Anterior and posterior support without lateral reinforcement | Anterior panel and sized posterior panel without lateral support |
| 637 | Anterior and posterior support with lateral reinforcement | Anterior panel and sized posterior panel with lateral support |
Important: These numbers identify each product family's manufacturer-defined kit options; they do not authorize swapping panels between Miami LSO and OAM.
What Makes Miami Lumbar Posteo Different?
Posteo pairs an adjustable lumbar compression belt with an extended upper-back support structure and axillary straps. Its specialized size chart uses the curved measurement from the top of the sacrum to C7 at the base of the neck. The design is particularly relevant when a clinician prescribes it for pain associated with a stable vertebral compression fracture; it is not simply a larger Miami LSO or a substitute for 456/464.
Choosing a Rigid Back Brace
Compare the exact model and kit configuration, prescribed support level, torso and belt measurements, and included panels before ordering. The Miami and OAM product families offer different support systems; their parts and accessories are not automatically interchangeable. A belt extension is an accessory, not a complete brace.
Fit and treatment: A qualified clinician or orthotist should determine the correct brace type, panel configuration, and adjustment for spinal injuries or recovery after surgery. Follow the instructions for the selected manufacturer part number.
Order the Correct Manufacturer Configuration
- Confirm the model: Miami LSO, Miami TLSO 456, Miami TLSO 464, Miami Lumbar Posteo or OAM Rigid Lumbar.
- Confirm rigid parts: For lumbar kits, match 626/627/631/637 where offered and the exact anterior/posterior/lateral panel package. For TLSO kits, identify whether anterior thoracic support is prescribed.
- Use the correct measurement: Miami TLSO 456/464 use waist-size, belt-width and spinal-profile selections; Miami LSO has belt-width and panel options; OAM has belt width, length and posterior panel size; Posteo uses measured back length.
- Check accessories separately: The Miami belt extension is one accessory, not a brace or set of both sizes. Match Slim 6-inch or Standard 8-inch only with a confirmed compatible Miami belt; do not assume OAM compatibility.
- Match the exact SKU: Confirm the manufacturer part number in the selected variant with your clinician or orthotist before checkout.
Rigid Spinal Braces vs. Everyday Back Supports
A flexible compression wrap for everyday lower-back discomfort is not the same product as an LSO or TLSO prescribed for spinal immobilization. For non-rigid supports and the longer-standing LSO/TLSO educational overview, see Back Support Braces & Lumbar Supports. For shopping by diagnosis or recovery, see Spinal Fracture & Post-Surgery Back Braces.
Frequently Asked Questions
What is the difference between an LSO and a TLSO back brace?
An LSO supports the lumbar and sacral regions of the lower back. A TLSO extends higher to support the thoracic and lumbar regions. Your clinician should determine which level of support you need.
Is a Miami LSO and TLSO belt extension a complete back brace?
No. The Miami belt extension is an accessory, not a complete brace. Confirm compatibility with the exact Miami model and selected belt configuration before ordering.
Are Miami and OAM Rigid Lumbar brace parts interchangeable?
Do not assume that Miami and OAM brace parts are interchangeable. Check the manufacturer model, part number, selected panel configuration, and fitting instructions.
How do Miami TLSO 456 and 464 differ?
Miami TLSO 456 uses a posterior thoracic extension and shoulder support. Miami TLSO 464 adds an adjustable anterior thoracic extension and additional strapping configurations. The prescriber selects the needed support arrangement.
Are Miami LSO and OAM Rigid Lumbar the same brace?
No. They are separate Ossur brace families with different belts, fit options and panel packages. Miami LSO offers 626, 627, 631 and 637 kits, while the OAM Rigid Lumbar listing offers 627, 631 and 637 kits. Match the exact model and SKU.
How do I choose a Miami Lumbar Posteo size?
Unlike waist-sized kits, Miami Lumbar Posteo uses a back-length measurement along the spinal curve from the top of the sacrum to the C7 vertebra at the base of the neck. Have a qualified fitter confirm the selected size.
How can I avoid ordering the wrong spinal-brace kit?
Confirm the exact model, prescribed support components, manufacturer SKU and measurements with your clinician or orthotist. Check belt width, posterior panel size, spinal profile and back length when those options apply.
