Congenital Femoral Length Discrepancy Pappas Type VIII in a 7 Year Old Child Treated by Femoral Lengthening Associated with Flexible Intramedullary Nailing

Congenital femoral length discrepancyCongenital femoral length discrepancy (Pappas type VIII) is associated with valgus deformity of the knee joint caused by hypoplasia of the lateral condylar and slight femoral neck anteversion or retroversion. Femoral lengthening and deformity correction can be successfully performed with the combined technique: circular external fixatorCircular external fixator and flexible intramedullary nailing. In this case the application of the abovementioned method is described. It enabled the period of external fixation to be shortened significantly while correcting the length discrepancy and deformity. The chosen moment of lengthening before prepubertal growth acceleration provided equal growth of the lengthened and intact femurs.
