■几种六足外固定器用于治疗骨折和畸形矫正。所有这些的一个特征是需要手动调节固定器支柱。这项研究的目的是介绍一种新颖的机器人系统,该系统可以自动调整支柱。
■使用带有AutoStrut系统的六足外固定器治疗了10例患者的各种骨畸形。这个新系统根据六足计算机辅助矫正计划自动调整固定器支柱。每次访问期间,对矫正的进展进行了评估(临床和影像学检查),并读取了支柱量表编号,并与原治疗计划进行了比较.
■所有患者在随访期间完成治疗,实现所有计划的纠正目标,除了一名因个人喜好而改用手动撑杆的患者。设备报警系统被激活一次,没有设备相关的不良事件。分心的持续时间为10至90天,分心指数为8至15天/cm。重新生成合并时间在1到7个月之间。总的来说,记录并分析了8例患者的48根支柱。总之,94%的最终支柱数量读数在计划读数和实际读数之间存在0mm至1mm的差异。指示精度高的自动调整。
■这项研究提供了初步结果,显示自动支柱可以成功取代手动支柱调整,提供有利于患者的重要优势,护理人员和外科医生。

OBJECTIVE: Several hexapod external fixators are used in the treatment of bone fracture and deformity corrections. One characteristic of all of them is the requirement for manual adjustment of the fixator struts. The purpose of this study was to introduce a novel robotic system that executes automatic adjustment of the struts.
METHODS: Ten patients were treated for various bone deformities using a hexapod external fixator with the Auto Strut system. This new system automatically adjusts the fixator struts according to a hexapod computer-assisted correction plan. During each visit, the progress of the correction was assessed (clinically and radiographically) and reading of the strut scale numbers was performed and compared with the original treatment plan.
RESULTS: All patients completed treatment during the follow-up period, achieving all planned correction goals, except from one patient who switched to manual struts due to personal preference. The device alarm system was activated once with no device-related adverse events. Duration of distraction ranged between ten and 90 days with a distraction index ranging between eight and 15 days/cm. Regenerate consolidation time between one and seven months. In total, 48 struts of eight patients were recorded and analyzed. In all, 94% of the final strut number readings presented a discrepancy of 0 mm to 1 mm between planned and actual readings, indicating high precision of the automatic adjustment.
CONCLUSIONS: This study presents preliminary results, showing that Auto Strut can successfully replace the manual strut adjustment providing important advantages that benefit the patient, the caregiver and the surgeon.
METHODS: Level II.
