Objective To evaluate the clinical and functional outcome of biological reconstruction by using pasteurized autograft and massive allograft after en-bloc resection of primary femoral diaphyseal sarcomas.Methods Retrospectively reviewed 19 consecutive patients with primary femoral diaphyseal sarcomas between Feb.2005 and Dec.2013.There were 11 males and 8 females with the mean age of 18 (2-38) years old.Thirteen patients were diagnosed as osteogenic sarcoma (OS),while five Ewing' s sarcoma (EWS) and one malignant fibrous histocytoma (MFH).All patients were treated with wide local excision,and 9patients were reconstructed by intercalary femur segmental allograft and 10 by pasteurized autograft.The median length of the resected bone was 16.9 (9-24) cm.15 segmental grafts were fixed by using plates including 10 intramedullary free vascularised fibular graft constructs,the other 4 segmental grafts were fixed by intramedullary nails.The average operation time for pasteurized autograft construct was 5.1 hours,while the time for intercalary allograft construct was 4.22 hours.Of 38 host-donor junctions,there are 28 diaphyseal junctions and 10 metaphyseal junctions.Results The average operation time for pausterized autograft construct tended to be longer than intercalary allograft (5.1h Vs 4.22h),although the difference did not reach the significance.Bone union occurred at a median of 10.3 months and 7.25 months at diaphyseal and metaphyseal junction for pasteurized autograft-host construct; 13.8 months at the diapyhseal junction and 11.5 months at the metaphyseal junction for allograft-host construct.Bone healing time of diaphyseal junction and metaphyseal junction between these two constructs were significant difference.Eight of 19patients (42.1%) developed complications:5 bone unnunion/fracture (including 1 subsequently developed local recurrence),1deep infection and 2 local recurrence (including 1 soft tissue recurrence).The mean overall follow-up was 33.5 months (3-107),five patients died of lung metastases,the cumulative patient survival was 76.5% at 2 years and 61.2% at 5 years determined by Kaplan-Meier method.All living patients except the MFH patients who received amputation,had a mean MSTS score of 83.7% (70%-95%).Conclusion Although the reconstructive procedure with pasteurized autograft is more complicated and needs longer operation time than allograft reconstruction,the bone healing time with autograft is significant shorter than allograft.Our observations suggest the pausterized autograft shell with intramedullary free fibular graft is strongly recommeded.
