Summary
Purpose of the study
Bone tumours are frequent conditions in children, and their surgical resection may lead to extensive defects which reconstruction is often challenging. Indeed, local conditions do not promote bone healing, and the achieved surgical result requires to be life-lasting. Capanna suggested a reconstruction technique combining massive allograft and free vascularized fibular flap. The first one is intended to withstand mechanical stress, and the second one offers biological and vascular support to improve bone healing and prevent infections.
Materiel and methods
We report our experience with this technique when applied to the lower limb in a prospective study including seven children, with a mean follow-up of 44 months.
Results
Bone healing was achieved by one single procedure in 85.7% of the cases, usually 7 months after surgery. Six out of seven patients achieved a final and long-lasting outcome, five of them following a simple surgical history. Partial weight-bearing was post-operatively allowed at about 2 months, full weight-bearing was initiated at about 5.5 months.
Discussion
A low complication rate was reported despite the extent of the disease and the type of the surgical procedure. Capanna’s combined reconstructive technique appears very efficient in the management of massive bone defects following tumour resection in children’s lower limb.
Level of evidence
Level IV. Retrospective therapeutic study.
