Resumen:
Intercalary femur and tibia segmental allografts were implanted
in 59 consecutive patients after segmental resection?
52 for malignant and seven for benign aggressive bone
tumors. The patients were followed up for an average of 5
years. Allograft survival was determined with the Kaplan?
Meier method. Infection, fracture, and nonunion rates were
determined. The overall 5-year survivorship for the 59 intercalary
allografts was 79%, and we found no significant
differences between allograft survival in patients receiving or
not receiving adjuvant chemotherapy. Infection and fracture
rates were 5% and 7% respectively. From 118 host-donor
junctions, 11 did not initially heal (9%). The nonunion rate
(10 of 69 osteotomies) for diaphyseal junctions was higher
than the rate (one of 49 osteotomies) for metaphyseal junctions.
Although some patients required reoperations because
of allograft complications, it seems that the use of intercalary
allograft clearly has a place in the reconstruction of a segmental
defect created by the resection of a tumor in the
diaphyseal and /or metaphyseal portion of the femur or tibia.
