Analysis of adult patients undergoing anterior spine fusions with Zielke instrumentation between January 1983 and November 1986 was performed. Objectives were to review results of surgical treatment and identify factors affecting results. Charts, 3 foot standing anteroposterior and lateral and supine maximal side bending radiographs were reviewed. Subjective data were obtained by telephone. There were 26 patients, average age 41 years. Average radiographic follow-up was 48 months. Indications were pain and curve progression. Average correction was 63% of the instrumented curve. Average change of lordosis was 8 degrees and kyphosis was 6 degrees. Apical vertebral rotation corrected an average of 37%. Complications were: eight hardware failures, one deep infection, and two psychiatric events. The high-risk groups: curves greater than 60 degrees, patients older than 50 years of age, and rigid curves.
对1983年1月至1986年11月间接受Zielke器械前路脊柱融合术的成年患者进行了分析。目的是回顾手术治疗结果并确定影响结果的因素。查阅了病历、3英尺站立位前后位和侧位以及仰卧位最大侧弯X线片。通过电话获取主观数据。共有26例患者，平均年龄41岁。平均影像学随访时间为48个月。手术指征为疼痛和侧弯进展。平均矫正度为器械固定侧弯的63%。前凸平均改变8度，后凸平均改变6度。顶椎旋转平均矫正37%。并发症包括：8例内固定失败、1例深部感染和2例精神方面事件。高危组包括：侧弯大于60度、年龄大于50岁的患者以及僵硬性侧弯。
