BACKGROUND Balloon kyphoplasty (KP) has been widely applied in the treatment of elderly patients with osteoporosis vertebral compression fracture (OVCF), but there has been little research on the pain relief effect. Therefore, we performed this study of patients who received KP. The study included a set of fluoroscopy tests and follow-up evaluation, which aimed to verify the effectiveness of kyphoplasty in controlling back pain associated with OVCFs. MATERIAL AND METHODS Forty-three OVCF patients underwent kyphoplasty: 21 were allocated to an intervention group and 22 were allocated to a control group, and the 2 groups received treatment with different KP instruments. The variation of vertebral height was measured on X-ray and change of signal of MRI was recorded. The pain was assessed by VAS score and diagram, and physical function was evaluated by ODI. The complications after surgery were recorded and collated during 2 years of follow-up. RESULTS The intervention group showed no significant difference on the VAS and ODI compared to the control group (p>0.05). There was no difference in the VAS with different degrees of radiological change (p>0.05). Signal change on MRI imaging was rare. CONCLUSIONS Kyphoplasty is a positive way to alleviate early-onset OVCF pain. The change of BME extent in the treated level is unrelated to the relief of back pain after KP.
球囊扩张椎体后凸成形术（KP）已广泛应用于老年骨质疏松性椎体压缩性骨折（OVCF）患者的治疗，但对缓解疼痛的效果研究较少。因此，我们对接受 KP 治疗的患者进行了这项研究。该研究包括一系列透视检查和随访评估，旨在验证 KP 在控制 OVCF 相关背痛方面的有效性。
43 例 OVCF 患者接受 KP 治疗：21 例患者分配到干预组，22 例患者分配到对照组，两组患者分别使用不同的 KP 器械进行治疗。X 线测量椎体高度变化，记录 MRI 信号变化。采用 VAS 评分和图表评估疼痛，采用 ODI 评估躯体功能。记录并比较术后 2 年随访期间的并发症。
干预组 VAS 和 ODI 评分与对照组相比无显著差异（p>0.05）。不同影像学改变程度的 VAS 评分无差异（p>0.05）。MRI 成像上信号改变少见。
KP 是缓解早发性 OVCF 疼痛的有效方法。治疗水平 BME 程度的变化与 KP 后背痛的缓解无关。
