研究目的:

比较选择性首尾端螺钉强化全部螺钉均强化和椎弓根螺钉内固定治疗伴骨质疏松腰椎退变性疾病的有效性及安全性。

Objectives of Study:

To comparing the effect and safety of cementing the apical and terminal pedicle screw and cement injections on all segments for osteoporotic spine with lumbar degenerative diseases.

药物成份或治疗方案详述:

将80例患者随机分为:骨水泥强化椎弓根螺钉固定组(cement-augmented pedicle screw group,CAPS组,40例)和选择性首尾端螺钉强化固定组(Cementing the apical and terminal pedicle screw,CATPS组,40例),其中CAPS组中所有椎弓根螺钉均强化,CATPS组总只有固定节段首尾端的螺钉强化,收集并比较两组患者性别、年龄、诊断、骨密度、体重指数(BMI)、糖尿病、高血压、吸烟、固定节段、是否采用腰骶固定、疼痛视觉模拟评分 ( visual analog scale,VAS)、术前功能障碍评分 ( oswestry disability index,ODI)、随访时间、手术时间、失血量、术后住院时间、住院费用、围手术期并发症(如肺栓塞/切口感染/下肢疼痛)、骨水泥渗漏率,螺钉松动率,融合率等指标。

Description for medicine or protocol of treatment in detail:

Eighty patients were randomly divided into cement-augmented pedicle screw group (CAPS group, 40 cases) and cementing the apical and terminal pedicle screw(CATPS group, 40 cases). The age, gender, diagnosis, bone mineral density, body mass index (BMI), diabetes, hypertension, smoking, fixed segment, lumbosacral fixation, visual analog scale (VAS), Oswestry disability index (ODI), follow-up time, operation time, blood loss, hospital stay, hospitalization costs, perioperative complications (such as pulmonary embolism/incision infection/lower limb pain), cement leakage rate, screw loosening rate, fusion rate were assessed

纳入标准:

Inclusion criteria

1. diagnosed with lumbar degenerative diseases, including lumbar spondylolisthesis, lumbar spinal stenosis, degenerative scoliosis, spinal instability; 2. patients suffered from severe low back pain and/or lower limb pain before operation and were ineffective after regular conservative treatment for more than three months. 3. patients with lumbar vertebral bone mineral density (BMD) measured by dual-energy X-ray absorptiometry and T <= -2.5 SD. 4. patients with posterior interbody fusion and using consecutive 2-level (fusion segment:L2-L4, L3-L5 or L4-S1) or 3-level (fusion segment: L2-L5 or L3-S1) pedicle screw implanting.

排除标准:

1. 伴新鲜椎体骨折、脊柱肿瘤或脊柱感染性疾病者; 2. 手术节段既往接受过腰椎内固定术; 3. 存在骨水泥强化禁忌症,对骨水泥或造影剂过敏者; 4. 内科合并症严重,无法耐受手术者。

Exclusion criteria:

1. patients with vertebral fracture, tumor or infection; 2. patients with lumbar surgery history; 3. allergy to bone cement ; 4. serious medical diseases or intolerance to operation.

随机方法(请说明由何人用什么方法产生随机序列):

通过随机数字网站(www.randomizer.org)产生两组随机数字,将装有随机数字的信封放入不透光的纸箱中。当受试者签署知情同意书,确认入组后,由随机化分配专员术前同过抓阄的方式取出信封,查看数字决定患者是分配在治疗组还是对照组。

Randomization Procedure (please state who generates the random number sequence and by what method):

Two groups of random numbers are generated through the random number website (www.randomizer.org), Envelopes containing random numbers are placed in opaque cartons. When the subjects signed the informed consent and confirmed their enrollment, the envelope was taken out by the randomized allocation commissioner.

盲法:

单盲,对患者实施盲法,即患者不知道自己分配在治疗组还是对照组。

Blinding:

Single blindness, the implementation of blind method for patients, patients do not know whether they are assigned to the treatment group or the control group.
