Solitary Bone Cyst: Treatment with Freeze-Dried Cancellous Bone Allograft

摘要: In a study of 177 solitary bone cysts treated by curettage and packing with freeze-dried cancellous allograft, ninety-seven (55 per cent) completely healed, sixty-four (36 recurred to such an extent that reoperation was indicated, sixteen (9 had non-progressive residual defect did not require operation. The over-all recurrence rate 45 cent. The ratio male female patients three one. Bone occurred more frequently in the younger (twelve years old or less) patients. humerus femur were most frequent, having predilection for proximal end bone. Cysts healed less often than those femur. There even lower common sites occurrence. Active (adjacent open growth plate) latent cysts. Cysts which postoperative roentgenograms reveal areas are incompletely packed have higher packed, usually being area. Freeze-dried allograft is satisfactory material use cyst.
