Abstract：
UNASSIGNED: The objective was to describe the technique and clinical outcome of microwave thermal ablation (MWA) and perfusion combined with synthetic bone substitutes in treating unicameral bone cysts (UBCs) in adolescents.
UNASSIGNED: A total of 14 consecutive patients were enrolled by percutaneous MWA and saline irrigation combined with synthetic bone substitutes. Clinical follow-up included the assessment of pain, swelling, and functional mobility. Radiological parameters included tumor volume, physis-cyst distance, cortical thickness of the thinnest cortical bone, and the Modified Neer classification system.
UNASSIGNED: The mean follow-up was 28.9 months (26-52 months). All UBCs were primary, and all patients underwent the MWA, saline perfusion, and reconstruction combined with a synthetic bone substitute session, except for one patient (7.1%) who required a second session. All patients had good clinical results at the final follow-up. Satisfactory cyst healing was achieved in 13 cases according to radiological parameters. Tumor volume decreased from a mean of 49.7 cm3 before surgery treatment to 13.9 cm3 at the final follow-up (p < 0.01). The physis-cyst distance increased from a mean of 3.17-4.83 cm at the final follow-up (p < 0.01). Cortical thickness improved from a mean of 1.1 mm to 2.0 mm at the final follow-up (p < 0.01). According to the proposed radiological criteria, our results were considered successful (Grading I and II) in 13 patients (92.9%) at the final follow-up.
UNASSIGNED: Percutaneous microwave ablation combined with a bone graft substitute is a minimally invasive, effective, safe, and cost-effective approach to treating primary bone cysts in the limbs of adolescents.

摘要：
■目的是描述微波热消融（MWA）和灌注联合合成骨替代物治疗青少年单房骨囊肿（UBC）的技术和临床结果。
■共纳入14例连续患者经皮MWA和盐水冲洗联合合成骨替代物。临床随访包括疼痛评估，肿胀,和功能流动性。放射学参数包括肿瘤体积，physis-囊肿距离，最薄皮质骨的皮质厚度，和改进的Neer分类系统。
■平均随访时间为28.9个月（26-52个月）。所有UBC都是主要的，所有患者都接受了MWA检查，盐水灌注,重建和合成骨替代治疗相结合，除了一名患者（7.1％）需要第二次会议。所有患者在最终随访时都有良好的临床效果。根据放射学参数，13例囊肿愈合满意。肿瘤体积从手术治疗前的平均49.7cm3减少到最后随访时的13.9cm3(p<0.01)。最终随访时，physis-囊肿距离从平均3.17-4.83cm增加（p<0.01）。最终随访时皮质厚度从平均值1.1mm改善至2.0mm(p<0.01)。根据拟议的放射标准，13例患者(92.9%)在最后一次随访时,我们的结果被认为是成功的(I级和II级).
■经皮微波消融联合植骨替代物是一种微创，有效,安全,和经济有效的方法来治疗青少年四肢原发性骨囊肿。
