目的探讨锁骨双极损伤的发生机制及其治疗效果。方法回顾性分析2013年1月至2023年1月在我院行锁骨双极损伤治疗的8例患者,均合并一处或多处其他部位损伤。根据锁骨损伤情况分为:双极脱位2例、肩锁关节脱位合并锁骨近端骨折2例、锁骨远端骨折合并胸锁关节脱位1例、双极骨折3例。随访期间观察骨折愈合情况、术后并发症及患肢肩关节活动范围,采用Constant评分、ASES评分及DASH评分评估患肢功能恢复情况。结果本组8例患者术后随访时间为7~23个月,平均(14.1±6.1)个月。术后3~6个月复查X线片,显示骨折愈合,胸锁关节及肩锁关节无再脱位,无手术相关并发症发生。末次随访时,患者均已恢复正常生活;患肢肩关节平均前屈角度为(155.0±19.5)°,平均外展角度为(149.0±10.9)°;平均Constant评分为85.5±6.7,平均ASES评分为88.3±5.6,平均DASH评分为5.6±3.1。结论锁骨双极损伤非常少见,常伴有合并伤及多发伤。损伤机制及其治疗方案的选择仍存在争议。适当的治疗方案能够取得满意的临床疗效。

ISBN: (纸本)9781467355339

Path planning for the aircraft is a highly challenging problem encountered in the feasibility of the path. A new approach is presented to obtain the optimal and feasible path. Firstly, the initial Voronoi diagram is generated based on the position of the threat points in the battlefield. The initial paths are planned based on the initial Voronoi diagram. Then, the initial paths are processed by the corner smooth method. And the optimal and feasible path is found by the Dijsktra search algorithm base on the processed paths. The threat and the distance of the optimal path are the minimum for the aircraft. Finally, the simulation results show the effectiveness of the proposed approach.
