Combined Deformities of the Femur and Tibia with 9 cm Shortening Treated with a Retrograde Femoral Motorized Lengthening Nail and a Tibial Plate

Combined lower extremity deformitiesCombined lower extremity deformities affecting both the femur and tibia can be corrected by well-planned one-stage correction with double osteotomies around the knee.Double osteotomies around the knee During the femur lengthening and deformity correction using straight lengthening nailsLengthening nails, lengthening along the anatomical axis requires detailed preoperative planning in order to prevent axis deviation. When combined deformities affecting the tibia and femur involve extreme shortening, a one-stage correction with a lengthening nail and a plate requires precise planning and surgical technique. In this chapter, we present a case of a 14 year old female with combined deformities affecting both the femur and tibia, complicated by a 9-cm femoral shortening resulting from physeal arrest. The patient was treated using a retrograde femoral motorized lengthening nail and a tibial plate.
