To determine the efficacy of percutaneous vertebroplasty in treating spinal metastases that result in pain or instability.
Thirty-seven patients (20 men, 17 women; aged 33-86 years) underwent 52 percutaneous injections of surgical cement into a vertebra (vertebroplasty) with fluoroscopic guidance in 40 procedures. Vertebroplasty was performed for analgesia in 29 procedures, stabilization of the vertebral column in five procedures, and both in six procedures.
Twenty-four of the 33 procedures performed for analgesia that were evaluated resulted in clear improvement; seven, moderate improvement; and two, no improvement. Improvement was stable in 73% of patients at 6 months. In the procedure performed for stabilization, no displacement of treated vertebrae was observed (mean follow-up, 13 months). Three patients had transient radiculopathy due to cement extrusion, and two patients had transient difficulty in swallowing.
Vertebroplasty of metastases is a minimally invasive procedure that provides immediate and long-term pain relief and contributes to spinal stabilization.
确定经皮椎体成形术治疗导致疼痛或不稳定的脊柱转移瘤的疗效。
37例患者（20例男性，17例女性；年龄33 - 86岁）在40次手术中，于透视引导下对椎体进行了52次经皮手术骨水泥注射（椎体成形术）。29次手术进行椎体成形术是为了镇痛，5次是为了稳定脊柱，6次是两者兼顾。
评估的33次镇痛手术中，24次明显改善；7次中度改善；2次无改善。73%的患者在6个月时改善情况稳定。在为稳定脊柱而进行的手术中，未观察到治疗椎体移位（平均随访13个月）。3例患者因骨水泥挤出出现短暂性神经根病，2例患者出现短暂性吞咽困难。
转移瘤椎体成形术是一种微创手术，可立即并长期缓解疼痛，有助于脊柱稳定。
