Bowing deformity causes abnormalities of the joints. The bowing deformity is a multiapical deformity. Therefore, usually two or more osteotomies are necessary to correct the deformity and to restore the mechanical axis of the lower limbs. As in a simple angular deformity, perfect preoperative planning is necessary before correction. It differs from simple angular deformity in that unlike simple deformity, it has multiple apices. Congenital anterior or anterolateral bowing of the tibia with partial sclerosis and narrowing of its medullary cavity is vulnerable to fracture and development of pseudarthrosis. Anterior bowing is of two types i.e. benign type and progressive type. Osteotomy at the apex of deformity to correct the bowing must be firmly avoided since it is very likely to result in pseudarthrosis. Double osteotomies for bowing deformity appear to be a satisfactory method of treating anterolateral bowing.
