The Boston brace, also known as the thoracic-lumbar-sacral orthosis (TLSO), is a type of brace used to treat scoliosis, a condition where the spine curves sideways. The brace is made of hard plastic and covers the torso from the armpits to the hips.

​

The Boston brace works by applying pressure to the curved parts of the spine, which helps prevent the curve from getting worse. It is typically worn for 18-23 hours a day, and patients are encouraged to remove the brace for activities like showering and sports.

​

The brace is most effective when used on patients whose spinal curves are between 25-40 degrees. It is not typically recommended for patients with curves greater than 45 degrees.

 

While the Boston brace can be uncomfortable and restrict mobility, it is a non-surgical option that can help prevent scoliosis from progressing and potentially requiring surgery. It is important for patients to follow their doctor's instructions for wearing and caring for the brace.
