Abstract
Introduction: Stabilization and bone grafting are the basic principles in the treatment of fracture non-union. Percutaneous bone marrow grafting has been suggested as an alternative source of osteogenic cells with an osteoindutive effect. Our aim is to assess prospectively, the efþcacy of percutanous bone marrow grafting in atrophic tibial non-union. Methods: 20 patients with established atrophic tibial non-union on the waiting list for surgical treatment were recruited. Under local anaesthesia bone marrow was aspirated from the iliac crest and injected into the fracture site. All patients were immobilized in above knee casts. A second injection was repeated at 6 weeks if there was no evidence of callous formation. The procedure was considered a failure if there was no union at six weeks following a third injection. Results: 19 patient were followed up clinically and radiologically until deþnite bone union or failure. Union occurred in 15 patients (75%), with an average time to union following the þrst injection of 14 weeks (range 6–22). Four patients showed no evidence of union. There were no cases of infection or complication at the donor or recipient site. Discussion: Percutanous bone marrow grafting is effective in inducing bone union. It is a minimally invasive technique and could be performed under local anaesthesia, with minimal cost and the potential to avoid a larger surgical procedure. All our patients were on the waiting list for open bone grafting but only 20% of them needed this. We recommend this technique for atrophic tibial non-unions with minimal deformity.
