Introduction: Spinal deformities are present for a very long time. One of the spinal deformity is scoliosis, which is characterised by the lateral tendency of the spine and the rotation of the vertebrae. Impact of spinal deformities can be reduced or at least their progress can be stopped with braces. Correction spinal ortosis Milwaukee, which is use for treatment of scoliosis, has changed during its first application. Orthosis modification was improved due to new research findings. Purpose: The purpose of my diploma paper is to present constructional development of the Milwaukee orthosis since first application until today. Goal is to demonstrate effectiveness of Milwaukee brace compared to other conservative treatments and to surgical treatment. Methods: In the diploma paper, descriptive method with systematic overview of already existing literature is used. Included is a time frame from 2006 to 2016, except the book Milwaukee brace, which is from 1976. Literature in English and Slovene was searched. Included are also articles from 1980 to 2003 due to lack of research in the last 10 years and due to little application of the Milwaukee brace. Results: 12 articles were analysed. The results are divided into four sections and they are showed in three tables of research findings on Milwaukee brace effectiveness compared to other conservative treatments and surgical treatments. The results in tables show numbers of patients participating in each research. Also shown are average age, time of treatment and the Cobb angle before and after treatment. Discussion and conclusion: After the examination of the literature it was discovered that the Milwaukee brace compared to other conservative treatment shows effective results, but between each method there are actually no differences. Compared with other braces for the treatment of scoliosis, Milwaukee brace is effective, but some TLSO and Boston orthosis proved to be more effective. The studies show that the surgically treated patients compared to patients treated with Milwaukee brace, can achieve better correction and the size of the curve.
