In a prospective cohort study in 94 patients with 3 years' follow-up the efficacy of rigid and semi-rigid transpedicular instrumentation for lumbar spine fusion was evaluated via three established scores. Patient groups were similar in respect of anthropometric data. The indication for using the semi-rigid technique was a fairly stable intraoperative situation; for the more common unstable situations, the rigid technique was chosen. Selecting implant rigidity on these criteria led to results with an improvement rate well within the upper success range reported in the literature. Among people in employment, a lengthy preoperative sick leave was an important predictor for unsatisfactory outcome.
在一项对94例患者进行了3年随访的前瞻性队列研究中，通过三种既定评分评估了用于腰椎融合的刚性和半刚性经椎弓根器械的疗效。患者组在人体测量数据方面相似。使用半刚性技术的指征是术中情况相当稳定；对于更常见的不稳定情况，则选择刚性技术。根据这些标准选择植入物的刚性，其结果的改善率完全在文献报道的较高成功范围内。在就业人群中，术前长时间病假是预后不佳的重要预测因素。
