[Are non-radical interventions in giant cell tumors justifiable?].

Eleven patients treated for giant cell tumors between 1966 and 1988 were followed up. Excochleations, i.e., thorough curettage and filling with spongiosa, were performed as a primary procedure in nine cases. Of these, en-bloc excision with Juvara plasty and amputation of the distal portion of the lower leg were necessary in one case each a week after confirmation of malignant degenerations. The mean duration of follow-up was 10.5 years; two recurrences were found among seven excochleations and one among four excisions. Taking function disturbances and their avoidance into account, excochleation and spongiosa filling appear justifiable as a form of primary therapy.
