Which spinal orthosis is a TLSO with a low-profile, more cosmetic design that can be worn under clothing and is used for mid-thoracic or lower scoliosis curves of 40 degrees or less, and may be used to treat spondylolisthesis and conditions of severe trunk weakness (e.g., muscular dystrophy)?

• A. Boston orthosis
• B. Milwaukee orthosis
• C. Thoracolumbar corset
• D. Cervical collar

Answer: (A)

The idea being tested is choosing a thoracolumbar orthosis that is low-profile, cosmetically discreet, and suitable for mild to moderate scoliosis in the mid-thoracic to lower thoracic region, with potential use for stabilization in conditions like spondylolisthesis or severe trunk weakness. The Boston orthosis fits this description best. It’s a molded plastic TLSO designed to sit snugly around the torso, providing needed spinal support while remaining slim enough to wear under clothing. It’s typically used for scoliosis curves up to about 40 degrees in the mid-to-llower thoracic region, and its supportive design can help limit progression and reduce motion, which is helpful in conditions like spondylolisthesis or when trunk muscles are very weak. The Milwaukee orthosis, by contrast, is a bulky cervicothoracic brace that includes a neck ring; it’s more conspicuous and aimed at higher thoracic curves, not the low-profile option described. The thoracolumbar corset provides general support and compression but doesn’t offer the same targeted, low-profile scoliosis correction or cosmetic wear under clothing. A cervical collar is for the neck and wouldn’t address a thoracic-lumbar curve. So the best match for a low-profile, under-clothing TLSO for mid-thoracic or lower curves around 40 degrees or less (and potential use in spondylolisthesis or trunk-weakness conditions) is the Boston orthosis.
