Anomalies of the natural correction of dysplasia of the hip and treatment proposals.
The spontaneous correction of hip dysplasia occurs at every level of growth of the lower limb and it may be inadequate at any of these levels. Every abnormality of correction may induce different troubles at any level of the lower limb. A complete clinical evaluation, X-ray with different special views and CT examination is mandatory. Every deformation in any of the three spatial planes must be detected for a good understanding of the defect. The authors describe the X-ray techniques necessary for a complete evaluation of the patient and propose a CT protocol to precisely calculate the different angles of torsion of the lower limb. The possibilities of surgical treatment at different levels of the lower limb (acetabular, femoral, tibial and ankle or foot level) in DDH are pointed out to address directly the proper procedure at the correct level of the pathology.
