[Modern surgical treatment of aneurysmal bone cyst using a synthetic bone substitute (Ceraform, a calcium phosphate ceramic)].
Aneurysmal bone cyst is a benign pseudotumoral dystrophy of bone, presenting expansive, destructive, nonresolutive features and often recurrence. A "stand-by" therapeutically attitude, in a survey manner, based on some spontaneous regression of certain areas of the aneurysmal cyst, due to thrombosis and fibrosis, is rarely advocated. When tumoral lesions are located in long bones and the bone length must be preserved, the bioptic curettage, followed or not by auto-grafting or cortical/cancellous allografting to bridge defect, represents the treatment of choice. The inconveniences encountered in using auto- or allografts have raised a growing interest towards synthetic bone substitutes. The most used of them are phosphocalcic ceramics due to their basic properties regarding interaction between bone and the substitution material, especially macroporosity Lately, we started to use (as clinical application) a bone substitute based on synthetic biphasic macroporous ceramic (CERAFORM), covering a wide range of procedures: benign tumors and dystrophies, spinal or joint arthrodesis, periprosthetic fractures, revisions following failures of primary total hip replacements. We obtained promising results, suggesting that in a situation with limited bone defects, as in clinical case presentation, if there exist a good contact and strong mechanical fixation, CERAFORM represents a reliable option comparing to allograft.
