摘要:

背景:研究证明经皮椎体成形是修复骨质疏松性椎体压缩骨折一种比较好的方法,但是具体的椎弓根入路方案研究尚少,采用单侧还是双侧经椎弓根入路经皮椎体成形来修复骨质疏松性椎体压缩骨折目前尚有争议。

目的:比较单侧及双侧经椎弓根入路经皮椎体成形对骨质疏松性胸腰椎体压缩骨折的修复效果。

方法:选择新疆喀什地区第一人民医院骨科2010年6月到2013年6月收治的118例随访时间大于1年的骨质疏松性胸腰椎体压缩骨折患者,根据随机数字表法分为两组,分别采取单侧和双侧经椎弓根入路经皮椎体成形方案治疗,每组59例。比较两组患者骨水泥注入量、骨水泥渗漏率、后凸侧凸Cobb角矫正度数、椎体平均高度变化、目测类比评分、Oswestry功能障碍指数、日常生活能力评分、健康调查简表SF-36评分及治疗后并发症发生情况。

结果与结论:单侧组骨水泥渗漏率(34%)比双侧组(37%)低,但差异无显著性意义(P=0.701 > 0.05)。两组后凸Cobb角矫正度数、侧凸Cobb角矫正度数差异均无显著性意义(P > 0.05)。两组间治疗前或治疗后1年椎体平均高度变化差异无显著性意义(P > 0.05),两组治疗后1年椎体平均高度均较治疗前显著改善(P < 0.05)。两组间治疗前或治疗后目测类比评分、功能障碍指数问卷评分、日常生活能力评分、健康调查简表评分差异均无显著性意义(P > 0.05),两组治疗后1年目测类比疼痛评分、ODI、日常生活能力评分、SF-36评分均较治疗前显著改善(P < 0.05)。单侧组骨水泥注入量比双侧组低(P=0.001 < 0.05),单侧组手术时间比双侧组短(P=0.000 < 0.05)。两组均未发生严重术后并发症。提示对骨质疏松性胸腰椎体压缩骨折患者行单侧和双侧经椎弓根入路经皮椎体成形治疗均有满意的止痛和修复效果,尤其是单侧入路具有水泥注入量少、渗漏率低、手术时间短的优势。

Abstract:

BACKGROUND: Studies have shown that percutaneous vertebroplasty is a better method to repair osteoporotic vertebral compression fractures, but there are still less specific schemes of transpedicular approach. Whether unipedicular or bipedicular approach is preferred is still controversial.

OBJECTIVE: To compare the clinical efficacy of percutaneous verterbroplasty via unipedicular and bipedicular approach on osteoporotic vertebral compression fractures.

METHODS: Totally 118 patients with osteoporotic vertebral compression fractures who had been admitted at the Department of Orthopedics, the First People’s Hospital of Kashi from June 2010 to June 2013 and followed up over 1 year were enrolled and randomly divided into unipedicular and bipedicular groups, with 59 in each group. 
These two groups were compared in terms of bone cement volume, bone cement leakage, kyphosis correction, vertebral height restoration, visual analog scale score, Oswestry disability index, activity of daily living scale score, SF-36 score, and postoperative complications.

RESULTS AND CONCLUSION: The cement leakage rate was lower in the unipedicular group (34%) than the bipedicular group (37.3%), but there was no significant difference (P=0.701 > 0.05). The kyphosis correction and scoliosis correction had no statistical significance between the two groups (P > 0.05). The mean vertebral height was improved significantly in both two groups at 1 year after operation (P < 0.05), but there was no difference between the two groups before and after operation (P > 0.05). There were also no significant differences between the two groups in terms of visual analog scale score, Oswestry disability index, activity of daily living scale score, SF-36 score before and after operation, but these indexes were all improved significantly in each group at 1 year after operation than before operation (P < 0.05). The bone cement amount of the unipedicular group was lower than that of the bipedicular group (P=0.001 < 0.05), and the operation time was also shorter in the unipedicular group than the bipedicular group (P=0.000 < 0.05). No serious complications occurred in the two groups. These findings indicate that percutaneous verterbroplasty via unipedicular and bipedicular approach has good analgesic and repair outcomes in patients with osteoporotic vertebral compression fractures, and the unipedicular approach is better than the bipedicular approach in the following aspects: less bone cement volume, lower cement leakage and shorter operation time.
