Corrective Anterior Bowing Tibial Orthosis

Tibial bowing specifically refers to bowing of the diaphysis of the tibia with the apex of the deformity directed anterolaterally, anteromedially, or posteromedially. The congenital anterolateral bowing of tibia and fibula is accompanied by shortening, a common denominator of "congenital pseudoarthrosis of the tibia" was 1stsuggested by Nicoll in 1969s. Understanding the nature of the deformity and establishing the correct diagnosis are very important. The aim of this project is to design and develop a modified orthosis for correction of anterior bowing of tibia. It was found that Anterior directed torsional force creates sufficient anterior translation of upper part of tibia with deflecting couple and such administration will resulting gradual reduction of bone bowing reference tubercular. Continuous & periodical changing in bending moment results appreciable reduction in bowing.
