Management Strategy for Unicameral Bone Cyst

治療單腔骨囊腫的方法包括經皮針吸合併局部注射類固醇、自體骨髓或去鈣骨質，甚至較侵入性的手術如骨刮除術及骨移植或部分切除術合併骨移植。但最佳的治療方法乃待研究。而單腔骨囊腫的治療目在於預防病理性骨折，促進囊腫癒合及避免囊腫復發及骨折。本研究共收集17位單骨囊腫（肱骨12位、股骨3位、腓骨2位）案例，以不同方式治療。包括保守性觀察、骨刮除術及骨移植合併內固定治療及中空螺絲連續減壓引流。研究建議經皮置入中空螺絲來促進囊腫癒合及預防病理性骨折，同時建立處理單腔骨囊腫的治療模式。

The management of a unicameral bone cyst varies from percutaneous needle biopsy, aspiration, and local injection of steroid, autogenous bone marrow, or demineralized bone matrix to the more invasive surgical procedures of conventional curettage and grafting (with autogenous or allogenous bone) or subtotal resection with bone grafting. The best treatment for a unicameral bone cyst is yet to be identified. Better understanding of the pathology will change the concept of management. The aim of treatment is to prevent pathologic fracture, to promote cyst healing, and to avoid cyst recurrence and re-fracture. We retrospectively reviewed 17 cases of unicameral bone cysts (12 in the humerus, 3 in the femur, 2 in the fibula) managed by conservative observation, curettage and bone grafting with open reduction and internal fixation, or continuous decompression and drainage with a cannulated screw. We suggest percutaneous cannulated screw insertion to promote cyst healing and prevent pathologic fracture. We devised a protocol for the management of unicameral bone cysts.
