[Disepiphysiodesis together with tibial osteotomy in the treatment of Blount's disease. Apropos of 2 cases].

The authors have studied two cases of Blount's disease in girls aged 9. They were treated by operative correction of premature epiphyseal closure, together with tibial osteotomy. In the first case, both procedures were performed simultaneously without hypercorrection, followed by a short period of non weight bearing and was a failure. In the second case, tibial osteotomy was performed first to produce hypercorrection. Division of the premature closure of the medial side of the growth-plate using cement was performed two months later. Weight bearing was not allowed for six months. There was a successful result. It is noted that a combination of tibial osteotomy and lateral epiphysiodesis was followed by a shortening of the limb and must often be repeated several times. The elimination of the premature closure of the medial side of the plate appears to be a better procedure when associated with tibial osteotomy.
