Our infection rate (7%) compares unfavorably with those in previous studies in which no infections were reported (table 5). On the other hand, infection rates after segmental allograft or endoprosthetic reconstructions typically range around 10%7,9,35-37. Infection resulted in graft removal in ve patients (four of whom were managed with a new biological reconstruction) in our series. The higher risk of infection following reconstructions of the tibial diaphysis may be explained by limited possibilities for soft-tissue coverage38. We did not use muscle aps; however, muscle transfers may be useful to reduce the risk of infection in these cases39. The infection rate was associated with the extent of cortical resection; it is conceivable that extensive resections require more soft-tissue dissection and take longer, thereby increasing the infection risk40.

Oncological Outcome
Most recurrences involved adamantinomas and parosteal osteosarcomas. These lesions recur frequently, especially after intralesional or marginal excision19,41-43. Until recent years, we routinely performed subperiosteal resections for these
