To assess the properties of facet fixation with the Facet Wedge system in patients affected by lumbar spinal stenosis (LSS).
Implant of intra-articular spacers is an emerging technique for lumbar degenerative disease.
This study included forty patients (Group 1) with symptomatic LSS in whom intra-articular spacers have been implanted along with microdecompression (MD) of the neural structures. Group 1 has been compared with a homogeneous group of patients with LSS treated with MD without intra-articular spacers implant (Group 2). Clinical findings have been observed preoperatively and 3, 6, 12 months postoperatively using dedicated questionnaires (Zurich Claudication Questionnaire, visual analog scale, and Oswestry disability index).
One year following surgical treatment, 87% of the patients presented with good improvement of symptoms and 97% referred satisfaction for surgery. Overall, patients of Group 1 presented with significantly better clinical outcome when compared with the control group ( < 0.01).
Intra-articular spacers showed significant and clinically meaningful improvements in pain and disability for up to 1 year. These findings need further studies and a longer follow-up.
评估腰椎管狭窄症（LSS）患者使用小关节楔形系统进行小关节固定的特性。
关节内间隔器植入是一种用于腰椎退行性疾病的新兴技术。
本研究纳入了40例有症状的LSS患者（第1组），这些患者在进行神经结构显微减压（MD）的同时植入了关节内间隔器。第1组与一组接受MD但未植入关节内间隔器的LSS同质患者（第2组）进行了比较。术前及术后3、6、12个月使用专用问卷（苏黎世跛行问卷、视觉模拟量表和奥斯维斯特残疾指数）观察临床结果。
手术治疗一年后，87%的患者症状有明显改善，97%的患者对手术表示满意。总体而言，与对照组相比，第1组患者的临床结果明显更好（<0.01）。
关节内间隔器在长达1年的时间里在疼痛和残疾方面显示出显著且具有临床意义的改善。这些发现需要进一步研究和更长时间的随访。
