Patient Case History: Nancy

Lengthening and Deformity Correction of a Femur Malunion Using an EBI Monolateral Frame


Patient Surgeon: S. Robert Rozbruch
Nancy is a 55 year-old woman who broke her leg as a child. She developed shortening and deformity. The valgus (knock-knee deformity) was causing arthritis and pain in her knee and the shortening caused back pain.


An osteotomy and acute correction of the femur was performed through a percutaneous approach. Gradual lengthening (4 cm) was accomplished with an EBI frame over 2 months to optimize leg lengths. Note the early new bone formation in the gap. Watch animation of procedure.


The frame was removed after 6 months after complete bone healing. Weightbearing and exercise were encouraged throughout the treatment.
