Chairback LSO Back Brace

A chairback LSO (lumbosacral orthosis) is prescribed when the lower back needs firm, structured support — following spinal surgery, a compression fracture, degenerative disc disease, or an acute lumbar injury. The name comes from the posterior rigid panels that cradle the lumbosacral spine much like the back of a chair, limiting flexion, extension, and rotation so the affected vertebrae can rest and heal. Physical therapists, orthopedic clinics, and post-op discharge planners reach for this style when a simple elastic belt won't provide enough motion restriction.

What sets a chairback design apart from a soft support is the balance it strikes: rigid or semi-rigid posterior stays deliver the immobilization a clinician is after, while a breathable body panel and adjustable closures keep it wearable through a full recovery. That wearability matters — an LSO only works when the patient actually keeps it on, and comfort drives compliance.

Our Chairback LSO Back Brace (11-1562-4) is an adult model in black, sized large for a 30 to 40 inch waist circumference. When ordering, measure the patient around the natural waistline rather than the hips, and confirm the brace sits with its panels centered over the lumbar spine. If a patient falls between sizes or requires a different color or fit for a facility's standing inventory, ordering by measured waist circumference is the most reliable approach.
