Purpose : To clarify the results of simple bone cyst(SBC) treatment in children by percutaneous autologous bone marrow grafting and xenografting.
Materials and Methods : We studied seven cases(4 males, 3 females) of SBC, which were treated by percutaneous autologous marrow and heterograft bone grafting from January 1996 to February 1999. Their mean age at surgery was 10 years(6 to 15), and the mean follow-up period was 35.6 months (20 to 52). Three cases were located in the proximal and middle humerus; three cases were in the proximal femur; and one cases occurred in the ilium. Mean volume was 14.7㎠(10 to 23). Six cases were active, and one was inactive. Five patients had a history of receiving a mean of 3.2 steroid injections. The mean quantity of bone marrow used in treatment was 14.3 ml (10 to 20), and the mean amount of Lubboc® heterograft bone (Transphyto S.A.Clermont Ferrand, France) used was 6.4 blocks (5 to 10). Results were analyzed using the modified Neer classification.
Results : Five cases completely healed with obliteration of the cyst cavity(Grade Ⅳ). T wo cases demonstrated sclerosis around a partially visible cyst(Grade Ⅲ). All treatment results were satisfactory and without intraoperative or postoperative complications.
Conclusion : Percutaneous autologous marrow and heterograft bone grafting is recommended as an effecitve treatment method for simple bone cyst. It offers ease of operative technique, a high rate of healing, a low recurrence rate, low morbidity, a low incidence of postoperative complications, and free from bone graft donor site problems.
