摘要
<strong>Background: </strong>Simple Unicameral and Aneurysmal Bone Cysts are benign lesions that may heal spontaneously especially after fracture which may be the first symptom. However, often size increases causing pain, and complications of fractures can severely compromise the patient.<strong> Aim:</strong> The results in a series of cases treated minimally invasive using a new device for the application of allogenic bone material appear highly promising and shall be presented. <strong>Patients and Methods:</strong> Eight consecutive patients with symptomatic Unicameral Bone Cysts (UBC) were treated by percutaneous instillation of Grafton<span style="white-space:nowrap;">?</span> DBF Putty (demineralised allogenic bone containing fibers) mixed with autologous bone marrow using the Kyphon<span style="white-space:nowrap;">?</span> Cement Delivery System (Medtronic), which allows the injection of this high viscosity paste by controlled high pressure. Five patients with Aneurysmal Bone Cysts (ABC) were treated accordingly after inactivation by Aethoxysclerol 3% and lacking bone formation. Using this approach a high rate of bone regeneration was observed in these patients at 8 months to 5 years follow-up (f/u). <strong>Conclusion:</strong> The presented technique of a minimally invasive biologic treatment led to highly satisfying results using the Grafton<span style="white-space:nowrap;">?</span> DBF Putty with its higher potential for bone regeneration than demineralized bone matrix not containing fibres (DBM).
