Blount designed it as early as 1957, and it became the choice of brace for most types of idiopathic scoliosis, even though it was esthetically unacceptable.

It is made up of two main parts: the base and the dynamic part.

The base is made up of the pelvic part, it is a thermo-plastic material that may be pre-fabricated in various sizes or constructed following casting. The whole construction will be based on this base, which must be well-constructed so that it fits perfectly and have the best possible result.

The dynamic part is made up of a central metal bar on the front, rising from above the pubic symphysis up to the area of the larynx, where it is joined to a metal support base for the chin, lined with foam material and leather. Behind the edges of the pelvis part, next to the vertebrae, two metal bars rise up to the occiput, where they are connected to a metal occipital support base lined with foam material and leather. Through the support bases, these metal bars aim at exercising pressure to the chin and the occiput, so as to elongate the spine, and they also create in the patient a continuous tendency to self-elongate.

The brace is completed by auxiliary means such as pads, which have a different shape and position depending on the type of scoliosis. Lateral thoracic pads are constructed from thermoplastic material that is processed on the patient's mold. These are connected with the relevant rear bar via a strap of adjustable tension, and on the front to the front bar via a metal strut, so that the thorax is not under pressure.

The action of the Milwaukee brace is exerted through two different mechanisms: the self-elongation and the three-point principle.

Any movement to extend the head results in the elongation of the spine, due to an inability to move the pelvis. This phenomenon increases, correcting lumbar and cervical lordosis.




Its other action is through lateral and lumbar pads, with the use of the three-point principle, but in a somewhat derotation action or rather and action resisting the rotation action of the vertebrae.

The patient was obliged to exercise daily with elongation exercises.





Unfortunately, the brace created deformations to the lower jaw with micrognathia ph

enomena. For this reason, but also for its bad esthetics, it was abandoned at the end of the p

revious century, despite being very functional, especially in high thoracic Scoliosis, and replaced by under-arm braces such as the Boston
