Thoracic lumbar sacral orthosis back brace
The system and method of an adjustable thoracic lumbar sacral orthosis back brace. The brace has a bowtie portion and a three point adjustment system. The bowtie is resistant to twisting due to internal reinforcement. The brace prevents trunk rotation and “hiking up” of the brace during adjustment by a wearer. The bowtie portion resists twisting of a thoracic panel via a channel formed by fixation to a thoracic stabilizer.
1. A thoracic lumbar sacral orthosis back brace, comprising:
a lumbar portion, comprising:
a central portion; and
a pair of belts, adjustably connected to the central portion;
a thoracic portion, comprising:
a central thoracic portion;
a thoracic panel; and
a pair of shoulder straps being connected at a first end of the thoracic panel;
a bowtie portion of fixed length being fixedly attached to a central thoracic stabilizer to form a channel for slidably engaging with a second end of the thoracic panel, further comprising a stay with a serpentine configuration embedded within the bowtie portion that extends at least a portion of a total horizontal length of the bowtie portion that provides additional rigidity to the bowtie portion; and
a pair of adjustment straps forming a three point adjustment system such that a first pair of adjustment points is located at free ends of the pair of shoulder straps, a second pair of adjustment points is located at each of a pair of fixed loops attached to respective end regions of the bowtie portion, and a third pair of adjustment points comprise a pair of connection points each located on one of the adjustable belts.
