Abstract
A follow-up study was performed on 22 patients with iliac crest prosthesis made from a glass ceramic containing apatite and wollastonite. These patients had undergone surgery to treat iliac crest defects involving the removal of the tricortical iliac bone between November 1993 and July 1996. Patients included 12 males and 10 females ranging in age from 43 to 73 years (average, 60). Clinical and radiological examinations were perfomed. Nineteen patients (86%) suffered no tenderness 18 patients (82%) showed bone formation. Only two patients suffered from dislodgment of the prosthesis. There were no cases of infection or pathological reactions at the reconstruction site. We therefore conclude that iliac crest prosthesis made from apatite/wollastonite glass ceramic are useful for reconstruction of the iliac crest defect.
