Introduction. Blount disease is developmental disorder of the lower leg, manifested by multiplanar deformity. Surgical treatment includes corrective osteotomy, lateral hemiepiphisyodesis, distraction of the proximal tibial physis, physeal bar resection and elevation of the medial tibial plateau. Case Outline. A case of a 4-year-old girl with bow legs is presented. Condition was recognized as Blount disease, type five. Both lower legs were operated by medial methaphyseal semi-osteotomy of the proximal tibia with the elevation of the medial tibial plateau. Prospectively, bilateral proximal hemiepiphysiodesis was done. Total follow-up period was eighteen years. The patient has no disturbances, clinical and radiographic findings are excellent. Improvement of the femoro-tibial angle is 22° on the right side, and 21° on the left side. Improvement of the varus angle is 7° on the right side, and 27° on the left side. Medial plateau depression is completely bilaterally reduced; improvement on the right side is 46°, and 51° on the left side. Conclusion. It is known today that multiplanar deformity is a part of the disease; varus, antecurvatum and internal rotation of the lower leg. By elevation of the medial plateau varus of the lower and antecurvatum component of deformity can be solved, while internal torsion cannot be solved. This deformity has to be either skillfully neglected, or corrected by an additional osteotomy by the elevation of the medial tibial plateau. Lateral hemiepiphysiodesis serves as extra stabilisator of the achieved result, and it is recommended to be done in combination with surgical elevation of the medial tibial plateau and derotative corrective osteotomy of the tibia.
