[Bone regeneration in the distal third of the fibula after resection of an aneurysmal bone cyst using an original technique].

Resection of the distal-third of the fibula for tumor may improve important static troubles of the ankle. The authors report an original technique which permits to benefit to osteogenic ability of periosteum to produce new bone in children and teenagers. This technique avoids to take out autograft and permits a complete regeneration of the fibula, using a "lift" procedure. It can be also used when a large bone graft has to be taken in the medial-third of the fibula and when the periosteum is separable enough to be completely preserved.
