经皮椎体后凸成形术对有裂隙征椎体压缩骨折的效果

PERCUTANEOUS KYPHOPLASTY FOR OSTEOPOROTIC VERTEBRAL COMPRESSION FRACTURE WITH AN INTRAVERTEBRAL CLEFT

目的探讨经皮椎体后凸成形术（PKP）治疗有裂隙征的骨质疏松性椎体压缩骨折的效果。方法存在裂隙征的骨质疏松性椎体压缩骨折病人27例，均行PKP治疗。分别于术前、术后24h行疼痛视觉模拟量表（VAS）评分、Oswestry功能障碍指数（ODI测定；以伤椎为中心行正侧位X线片检查，测量手术前、后伤椎前缘高度及伤椎Cobb角。结果27例病人手术顺利。11例病人骨水泥渗漏，未发生神经症状。与术前比较，病人术后VAS评分、ODI、伤椎Cobb角降低，伤椎椎体前缘高度增高，差异均有显著意义（t=11．730～50．433，P〈0．01）。结论PKP是治疗有裂隙征骨质疏松性椎体压缩骨折的有效手术方式。

Objective To assess the effectiveness of percutaneous kyphoplasty （PKP） in the treatment of osteoporotic vertebral compression fracture （OVCF） with an intravertebral cleft. Methods PKP was performed in 27 OVCF patients with a cleft sign. The visual analogue scale （VAS） and Oswesty disability index （ODD were used to score pain and measure ODI before and 24 h after surgery. The anterioposterior and lateral film-the affected vertebra being made to be the central point was taken to measure the height of anterior edge of injured vertebra and the Cobb angle of the injured vertebra. Results The surgeries in all the 27 patients were completed smoothly. Cement leakage was noted in 11 patients, with no any symptoms of nervous system were observed. Postoperatively, the VAS, ODI, and the Cobb angle of the injured vertebra decreased, the height of the anterior edge of injured vertebra increased, as compared with before surgery, the differences were significant （t=11. 730-50. 433, P〈0.01）. Conclusion Percutaneous kyphoplasty is an effective surgical procedure in the treatment of osteoporotic vertebral compression fractures with an intravertebral cleft.
