We report the case of a 62-year-old woman with marked valgus and limitation
of extension of the right knee joint as the result of a supracondylar frac
ture of the femur, originally treated by internal fixation with a dynamic c
ondylar screw. Two years later, revision osteotomy with retrograde femoral
nailing was carried out to achieve varisation and improve extension. Within
a week of operation the patient's right leg was fully weight bearing with
normal axial positioning. A retrograde locking nail provides satisfactory a
nd stable internal fixation in cases of revision.
