Intramedullary nails are the most appropriate implants for stabilisation, but if they are inserted from the greater trochanter, they cannot correct the varus deformity enough. PATIENTS AND METHODS: We have developed a special intramedullary nail that can be inserted from the osteotomy site and can be driven retrograde into the femoral ne..View full abstract
