Simple bone cysts in teenagers treated by grafting of bioactive glass and autologous bone marrow / 中国矫形外科杂志

ABSTRACT

[Objective]To investigate the therapeutic results of grafting with bioactive glass and autologous bone marrow for simple bone cyst in teenagers. [Method]From April 2005 to October 2007,16 teenagers with simple bone cyst were reported.There were ten males and six females with a mean age of 18.5 years(range 12 to 30 years).Eight cysts were in the proximal humerus,five in the proximal femur,two in the proximal tibial and one in the distal end of radius.Lining of cavity was removed thoroughly with a curet.The cyst cavity was filled with the mixtures of 45s bioactive glass and autogenous red bone marrow.Five cases of pathologic fracture were fixed with steel plate or intramedullary nail.[Result]All 16 cases of cysts were ossified radiolo gically within six months,with an average time to syst healing of 18 week.A follow-up of 6 to 32 months(mean 18 months) showed satisfactory healing without complications.[Conclusion]The combined grafting with bioactive glass and autologous bone marrow appears to be an effective and simple treatment for simple bone cyst in teenagers.
