Abstract

BACKGROUND

The purpose of the current study was to use the Iliac Bars Lever Reduction and Fixation System (IBLRFS) for Grades 1 and 2 spondylolytic spondylolisthesis, evaluate its stability and reductive efficacy, and examine the complications.

METHODS

Between April 2005 and August 2006, 44 patients with Grades 1 and 2 spondylolytic spondylolisthesis were treated surgically: 21 patients underwent posterior Iliac Bars Lever Reduction and Fixation (IBRLFS), 23 patients were treated with traditional stabilization and reduction systems (SRS). The follow-up periods ranged from 1 to 2 years (mean, 1 year and 2 months). The clinical outcome, fusion rate, average percentile degree of displacement, displacement angle, sacral inclination, ratio of intervertebral height, and complications were evaluated. Operating time, blood loss, and duration of hospital stay were compared.

RESULTS

There were no statistically significant differences between the 2 groups in blood loss, recovery rate, and radiographic results. However, there were statistically significant differences in operating time (P < .05), duration of hospital stay (P < .05). There were no cases of nonunion in the two groups. In the IBLRFS group, preoperatively, the average percentile degree of displacement, displacement angle, sacral inclination, and ratio of intervertebral height were 23.48% ± 5.36%, 2.2° ± 1.1°, 29.4° ± 6.5°, and 0.68 ± 0.21, respectively. Postoperatively, the respective measurements were 6.47% ± 1.49%, 10.3° ± 3.3°, 42.6° ± 8.1°, and 0.85 ± 0.12. No patients experienced major complications. In the SRS group, preoperatively, the average percentile degree of displacement, displacement angle, sacral inclination, and ratio of intervertebral height were 21.78% ± 5.16%, 2.3° ± 1.0°, 26.4° ± 8.5°, and 0.62 ± 0.25, respectively. Postoperatively, the respective measurements were 6.34% ± 2.01%, 9.8° ± 2.1°, 44.1° ± 7.6°, and 0.79 ± 0.23. One patient experienced a badly placed screw in the right pedicle of lumbar 4.

CONCLUSIONS

This kind of new fixation system (IBLRFS) was shown to be useful in the treatment of spondylolisthesis, and its use was associated with minimal complications after 14 months of mean follow-up.

LEVEL OF EVIDENCE

Therapeutic, case studies (level 4).

摘要

背景

本研究旨在使用髂骨棒杠杆复位固定系统（IBLRFS）治疗1级和2级峡部裂性腰椎滑脱症，评估其稳定性和复位效果，并检查并发症情况。

方法

2005年4月至2006年8月期间，44例1级和2级峡部裂性腰椎滑脱症患者接受了手术治疗：21例患者接受了后路髂骨棒杠杆复位固定术（IBRLFS），23例患者采用传统的稳定和复位系统（SRS）进行治疗。随访时间为1至2年（平均1年零2个月）。评估了临床结果、融合率、平均位移百分度、位移角度、骶骨倾斜度、椎间高度比以及并发症情况。比较了手术时间、失血量和住院时间。

结果

两组在失血量、恢复率和影像学结果方面无统计学显著差异。然而，在手术时间（P < 0.05）、住院时间（P < 0.05）方面存在统计学显著差异。两组均无不愈合病例。在IBLRFS组中，术前平均位移百分度、位移角度、骶骨倾斜度和椎间高度比分别为23.48% ± 5.36%、2.2° ± 1.1°、29.4° ± 6.5°和0.68 ± 0.21。术后，相应测量值分别为6.47% ± 1.49%、10.3° ± 3.3°、42.6° ± 8.1°和0.85 ± 0.12。没有患者出现严重并发症。在SRS组中，术前平均位移百分度、位移角度、骶骨倾斜度和椎间高度比分别为21.78% ± 5.16%、2.3° ± 1.0°、26.4° ± 8.5°和0.62 ± 0.25。术后，相应测量值分别为6.34% ± 2.01%、9.8° ± 2.1°、44.1° ± 7.6°和0.79 ± 0.23。一名患者在腰4右侧椎弓根出现螺钉位置不当。
