[The use of hydroxyapatite in the surgical treatment of benign non aggressive bone lesions]

The authors studied, in the period 1990-1993, 31 patients with benign non aggressive bone lesions, surgically treated with intralesional resection followed by the introduction of hydroxyapatite. Their follow-up was two years and one month. The authors discussed the surgical indications, the operative technique employed, and the post-operative results which were considered to be good in 29 of the patients studied. Occurred complications in three patients: local infections in two and sterile fistula in one. It is concluded that the use of hydroxyapatite is a good option as substitute of the autologous bone graft.
