AIM: It was the aim of this retrospective study to evaluate the frequency of recurrences and complications in @entity1 treated by conventional surgical methods at our institution between 1980 and 1996 and to compare them to those observed in @entity1 treated by minimal invasive methods reported in the literature. METHOD: 70 @entity1 with @entity10545 located at the extremities were treated by conventional surgical treatment. 51 @entity1 underwent curettage and 19 @entity1 had en bloc resection. After curettage an additional stabilising plate was implanted in 12% of the cases, after en bloc resection in 68%. RESULTS: There are 66% event-free @entity1 after curettage versus 47% after en bloc resection. Local recurrence rate after curettage was 7%, after en bloc resection no @entity1 developed a recurrence. In both groups a postoperative @entity174 was observed. Persistent @entity158 due to the implant was reported by 7% after curettage and by 24% after en bloc resection. CONCLUSION: The rate of complications rises with increasing invasiveness and it is necessary to balance the security concerning a local recurrence and the danger of persistent @entity282 . Curettage is the surgical method of choice in the therapy of the @entity10545 , en bloc resection is justified only for recurrent lesions. Curettage is an alternative to minimal invasive methods in cases of superficially located @entity10545 or in cases of unfavourable locations of the nidus (near joint or growth plate, inaccessibility).
