May bone cement be used to treat benign aggressive bone tumors of the feet with confidence?

Abstract

Using bone cement for the reconstruction of defects created after curettage of benign aggressive bone tumors is among acceptable methods. The study aimed to assess the effect of bone cement used in aggressive bone tumors in the feet on the function of the feet. Five patients were reviewed. They were treated between 2004 and 2010. Three cases were female and two male. Their age ranged from 16 to 55 with an average of 34.8. Follow up period ranged from 14 to 86 months with an average of 34. Two cases were giant cell tumor of bone located in calcaneus and 3 were solid variant aneurysmal bone cyst located in talus, navicular and first proximal phalanx. None had any previous treatment. A biopsy was done in all cases. Treatment was curettage, high speed burring (except phalanx case), and filling the cavity with bone cement. The case located in talus recurred and re-operated 1 year later doing the same procedure. Final evaluation included physical examination, X-ray and Maryland Foot Score. No recurrence was present in the final evaluation. No problems were detected related to bone cement. Maryland Foot Scores ranged 84-100, average of 94. Cement integrity was not disturbed. The procedure is found not to effect foot functions adversely.
