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.
■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。
