Aims: Study our experience and short term results using a mix of osteoconductive (HA) and osteoinductive (AGF) materials. Methods: From October 2001 until June 2002, we have treated bone defects in 9 patients. Seven male and 2 female. Mean age 10.4 years (range 4–18 years). Mean follow-up: 5.6 months (range 3–9 months). AGF was obtained after autologous blood centrifugation according to blood volume, knowing the patient height and weight (Nadler Score). AGF was obtained through previous concentrate of platelets and red cells, with a further concentration, reducing its volume to 1/3. 10 c.c. of thrombin (500 UI) and HA (500R) were added, just before applying it to the patient. Total surgery time for preparation AGF was 20–30 minutes. Clinical cases treated were: varus osteotomy in Perthes (1 case- 11%); curettage in osteomyelitis (2 cases- 22%); essential cyst, after conventional corticoid treatment failure (2 cases- 22%); forearm pseudoarthrosis (2 cases- 23%) and triple arthodesis by valgus pronated spastic foot (2 cases- 22%). We never use autologous iliac graft with AGF- HA. Results: We have obtained radiological and clinical consolidation in all bone defects after 3–4 months. Radiological success is not clear after 4 months in one of the osteomyelitis cases (12’5%). Conclusions: 1. The iliac graft harvest morbility is about 9.4%- 49%. 2. A 2nd approach is avoided in children and adolescents. 3. With the use of AGF- HA we avoid morbility, diseases transmission, reduced surgery time and offer an alternative to autologous grafting.
