Braces Function from Mechanisms of Action.[edit]

Despite differing names, braces for idiopathic scoliosis all have one thing in common; the application of forces to guide a crooked spine to becoming more corrected during peak vertical velocity of spinal growth spurts. These forces are usually oriented in triangles, and they use common parts of the anatomy such as the axilla (arm-pit) curve apices (peaks) and the pelvis. The goal is to achieve a stable out-of-brace spines at skeletal maturity. Many authors have suggested that if a curve, or curves are less than 40 degrees and are stable in a mature spine, they likely will not progress. 40 degrees to 50 degrees are considered a grey zone, in other words there are some who believe that any curve at or greater than 41 degrees, should have surgery to correct the curve with an implant, and stabilize the curve with a surgical fusion. Others believe that the physical environment of a 40 degree curve warrants waiting to see if progression will exceed 50 degrees, however, most professionals believe that any curve that exceed 50 degrees probably needs surgery.

The fashion of how these forces are delivered gives each orthosis its unique qualities. A Milwaukee brace employs polymer based pads (Axillary, thoracic, lumbar) placed at the previous parts of the anatomy delineated earlier in this section, and the use force triangulation that shows these forces are synergistic. This means that if you tighten any pad within the triangle. That forces of the reactive pads will synergistically answer to the initial pad tightening The Boston Brace employs pads in the same areas that are triangulated and synergistic, however these pads are mounted to the walls of the brace.

The group that designed the Rosenberger brace analyzed that if these forces are cyclical, they would benefit by realizing greater curve correction. So the used soft pads, mounted on Dacron slings that are overtightened independently from the brace with forces delivered with high specificity, they will constantly load the curves and will roam with the changes of curve correction, and activities of daily living provided the cyclical loading as they are free to move against a person with a curve.

The Wilmington and Rigo-Chenau bracing has the walls of the brace already set in correction, achieved in CAD or plaster casts, and these are how they deliver forces.

It is a disservice to an individual to allow correction to "bottom-out" at less than the limits of correction. A side bending x-ray can be used to find correction limits.

All these methods have been used for decades and are reported in peer review literature with these methods being quite mechanically thought provoking. 149.75.189.53 (talk) 23:45, 16 April 2024 (UTC)[reply]
