Percutaneous Curettage and Local Autologous Cancellous Bone Graft: A Simple and Efficient Method of Treatment for Benign Bone Cysts

Background: Several treatment modalities have been reported to minimize the recurrence after surgical treatment of benign bone cysts. In this study, we evaluated local tumor control, recurrence rate, and bone healing of benign bone cysts after treatment with a simple technique, percutaneous curettage and a local autologous cancellous bone graft. Methods: Retrospective analysis of the records of ۱۶ patients diagnosed with benign bone cysts between ۲۰۰۳ and ۲۰۱۰. We documented the demographic data, radiographic signs of healing (progressive decrease in radiolucency, remineralisation, ossification, consolidation of the cyst, and reconstitution of the bone), healing rate, postoperative complications, and recurrence. Results: Seven of the ۱۶ patients (۴۳.۷۵%) were diagnosed with a simple bone cyst (SBC), while nine (۵۶.۲۵%) had an aneurysmal bone cyst (ABC). On average, radiographic signs of healing were present within ۳–۶ months, but in two patients these signs presented after ۱۶ months. During the follow-up period, there was no difference in the healing rate between patients with SBC and ABC; no signs of deep or superficial wound infection, no postoperative fracture, and no recurrence in any case over an average of ۶.۳ years of follow-up. Conclusion: Treatment of benign bone cysts (SBC/ABC) with minimally invasive percutaneous curettage and a local autologous cancellous bone graft is a simple and effective modality with a promising outcome in the local control of recurrence and in enhancing bony consolidation. Level of evidence: IV
