Herbert sustained a femur fracture many years back. This healed in a poor position with deformity and shortening.

He had back pain, 4 cm of shortening, and hyperextension of his knee.

An osteotomy of the femur was done to straighten the femur and the ISKD rod was implanted. Gradual lengthening followed without the need for external fixation. After 5 weeks, full lengthening was achieved.

Final result shows equal leg lengths, no deformity ...

... and full hip and knee mobility.
