经皮椎体成形术的临床应用及近期疗效

Clinical application of percutaneous vertebroplasty and its early curative effect

目的 :探讨椎体成形术治疗骨质疏松椎体压缩性骨折、椎体肿瘤的早期临床效果、适应证与禁忌证、并发症的预防。方法 :对 2 2例骨质疏松椎体压缩性骨折病人的 2 5个椎体以及 5例椎体肿瘤 7个椎体 ,经皮椎弓根向椎体内穿针并注入聚甲基丙烯酸甲酯 (PMMA)。结果 :2 7例病人平均每个椎体注入骨水泥 4 5mL ,X线检查骨水泥充填良好 ,骨折复位满意。术后疼痛明显减轻或消失 ,所有病例经平均 12 3个月随访 ,疼痛未明显加重 ,椎体高度无继续丢失。结论 :椎体成形术治疗骨质疏松椎体压缩性骨折及椎体肿瘤 ,能够迅速缓解疼痛 ,增加椎体的强度和脊柱的稳定性 ,是安全有效的微创技术。

Objective To study the method of percutaneous vertebroplasty (PVP) and investigate its early clinical efficacy. Methods Twenty seven patients were treated by the injection of polymethylmethacrylate (PMMA) into vertebraes under C arm X ray guidance, including 22 cases with painful osteoporotic vertebral fractures of 25 vertebraes and 5 tuomr cases of 7 vertebraes. Results The procedure was successful in all patients. Average cement volume is 4 5 mL pervertebraes in 27 cases. Cement injection in vertebraes are good under X ray check. Pain release were excellent or good after PVP. All cases wre followed up 12 3 moths, no vertebraes high lost or pain increase in follow phases. Conclusion PVP is a safe and feasible treatment for patients with hemangiomas and vertebral fractures caused by malignancies ad osteoporosis.
