Then it will be fabricated bye orthotist and worn by patient. According to clinical principles, the brace should be as fit as possible with limb form. Also, an individual, walks and sits with his or her brace. Brace functions around joint motion axis. Quality and exact place of movement is define by biomechanical principles. Therefore, brace should be adapted with biochemical principles of the limb. Materials & Methods: A brace is made up several components which are assembled through acceptable technical orthopaedic methods and this procedure should be done without omission or neglect. If orthotist has enough scientific knowledge and observes all details, he or she will fabricate a perfect brace. We considered fabricated long leg brace according to this principle to meet study objectives while answering some question of study, we will disguss on the finding of our assessment. Also, we examine some possible deviations with accured by unsuitable fabrication, more over we suggest that some failur in designing procedure which leads to such deviation material and methods: In this descriptive analytic cross sectional study, long leg braces of 193 clients who were selected by random stratified sampling method, were evaluated by a previously designed questionare . Results: A. By assessment of 7 variables, it was revealed that 28.86% of manufactured braces, was not adapted with defined fundamentals, biomechanically. B. By evaluation of 9 variables, it was made known that 30 % of produced braces was not adapted with established fabricating fundamentals of lower limb braces clinically. C. By examination of 23 variables it was find out that 25.4% of fabricated braces, it was observed, which has some failures by attention to defined fabricating technical orthopaedic fundamentals. Conclusion: All the details, fabrication and design procedures should be carefully observed and associated theories should be considered.
