Continuous Decompression Using a Cannulated Ceramic Pin for Simple Bone Cysts

Purpose. To report the outcomes of continuous decompression using a cannulated ceramic pin for simple bone cysts (SBCs). Methods. Seven boys and 3 girls aged 7 to 16 (mean, 11) years with SBCs underwent curettage and continuous decompression using a cannulated ceramic pin. The pin was made of hydroxyapatite and tricalcium phosphate. The clinical course, radiological findings, and complications were retrospectively assessed. Results. The mean follow-up duration was 41 (range, 12–84) months. Five patients were evaluated as ‘healed’, 2 as ‘healing with defect’, one as ‘persistent cyst’, and 2 as ‘recurrent cysts’. No peri-operative complications were encountered. One patient had a postoperative fracture at the pin insertion site. Seven patients had pain relief and good outcomes; 2 had a thin cortical rim and complained of occasional pain and their sports activities were restricted. Conclusion. Decompression using a cannulatedceramic pin for SBCs is minimally invasive, highly osteoconductive, and does not require bone grafting or a second operation to remove the device.
