Delayed Regenerate Bone Formation in a Seven Year Old Boy with Fibular Hemimelia Undergoing Tibial Lengthening

This is a case of an 11 year old boy with Fibular hemimelia Type IA who had been followed for 4 years. He then underwent tibial lengthening with a standard Ilizarov frame. He developed poor regenerate bone formation that was addressed with the accordion technique, and targeted lengthening was reached. However, 2 weeks after removal of the fixator, he sustained a fracture of the regenerate that was treated with elastic nailing. He subsequently underwent distal medial hemi-epiphysiodesis of the femur on the affected side. At the latest follow-up, he had an LLD of 1.5 cm and satisfactory alignment of his lower limbs.
