Which spinal orthosis is characterized by a molded plastic jacket with one anterior and two posterior uprights attaching to a neck/chest ring and is used for scoliosis up to 40 degrees?

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

Answer: (A)

Spinal bracing for scoliosis uses designs that apply corrective forces along the spine, and the one described with a neck ring and uprights is a classic example of a Milwaukee-type orthosis. This brace is a molded plastic jacket that includes a neck/chest ring and upright bars—one anterior and two posterior—that connect to the ring and grid the torso. The neck ring lets the orthosis guide and derotate the upper spine while the uprights run down along the back, providing a rigid frame to hold the spine in a corrected position. It’s specifically noted for use in scoliosis curves up to about 40 degrees, especially in skeletally immature patients, where growth can be guided while maintaining correction. The Boston brace, by contrast, is a thoracolumbar–sacral orthosis that wraps around the torso without a neck ring, focusing correction through padding and contouring of the trunk. A cervical collar is designed for neck issues, not scoliosis, and a lumbar corset provides general lower back support rather than the targeted derotation and control needed for scoliosis.
