The treatment of infantile coxa vara with the external circular fixator

Coxa vara worsens as it evolves, and is often accompanied by other femoral deformities, such as hypometria, axial knee deviations, and rotational deformity. Traditional surgical techniques, especially intracapsular femoral neck osteotomy, are difficult to execute and often cause joint stiffness while not sufficiently correcting the coxa vara or the other deformities, in particular hypometria. For these reasons this study used the external circular fixator to simultaneously correct these deformities. The results are presented after discussion of technical details.
