Blount's disease is bowleg seen in children caused by disturbed ossification of the proximal metaphysis and medial epiphysis of the tibia. In early stages, this disease often responds well to conservative treatment and prognosis is good. In advanced cases, invasive treatment is indicated, but residual varus deformity, relapse of deformity, unequal leg length, etc. are not uncommon, requiring multiple operations treatment difficult. We recently encountered three cases of Blount's disease. Two were treated by the conventional method, and one invasively by the Illizarov procedure. These experiences are reported in this paper.<BR>The two cases treated with the conventional method required multiple operations, but the final outcome evaluated radiographically and clinically was more or less satisfactory. For the case treated with the Ilizarov procedure, three-dimensional correction of varus deformity, internal torsion, and shortened leg was achieved during a single operation. The postoperative course of this case has been favorable, although the follow-up period is short. Different methods of treatment for this disease, especially the conventional invasive procedure and the Ilizarov procedure, were compared.
