目的:阐述与股骨逆行髓内钉相关的股骨解剖学参数的研究进展。方法:广泛查阅近年国内外相关文献并结合基础研究及临床相关经验,总结分析与股骨逆行髓内钉密切相关的几个重要解剖参数的临床意义及相关测量结果和测量手段等。结果:目前临床常用的髓内钉大多数仍为参照国外人体解剖参数而设计的,而国人股骨解剖参数与西方人种确实存在差异。同时发现股骨长度、股骨标准冠失状面的确定及股骨曲度的相关研究等对股骨逆行髓内针的设计有着决定性的影响。结论:在股骨远端骨折的治疗中,股骨逆行髓内钉有着不可替代的作用,有必要设计一款新型股骨逆行髓内钉使其更符合国人特点。Objective: This study aims to review the advancements in research concerning femoral anatomical parameters pertinent to retrograde intramedullary nails. Methods: Through a comprehensive examination of recent literature both domestically and internationally, alongside foundational research and clinical experience, we summarized and analyzed the clinical significance of several key anatomical parameters closely associated with femoral retrograde intramedullary nails, as well as relevant measurement outcomes and methodologies. Results: Currently, the most commonly utilized intramedullary nails in clinical practice are still designed based on foreign human anatomical parameters;however, it is evident that the anatomical characteristics of the Chinese femur differ significantly from those of Western populations. Furthermore, findings indicate that factors such as femoral length, standard coronary deformity assessment of the femur, and investigations into femoral curvature exert a critical influence on the design of retrograde intramedullary nails for the femur. Conclusion: Retrograde intramedullary nail fixation plays an indispensable role in managing distal femoral fractures. Therefore, there is a pressing need to develop new designs for retrograd
目的探究三维导航技术辅助经皮骶髂螺钉治疗骨盆后环骨折的临床疗效。方法回顾性分析该院2015年3月—2016年3月收治的31例骨盆后环骨折患者临床资料作为研究对象,患者均在三维导航技术辅助下行经皮骶髂螺钉治疗,观察围手术期临床指标、Majeed及Matta评分、并发症发生率。结果手术中导航建立时间平均为（20.04±2.08）min,每枚螺钉置入平均时间为（29.31±3.02）min,术中出血约为10-20 m L,住院时间（9.38±2.41）d;Majeed评分总体优良率为100%,Matta评分总体优良率为93.54%;仅出现1例伤口感染,并发症发生率低。结论三维导航技术辅助经皮骶髂螺钉治疗骨盆后环骨折可以有效缩短骨折愈合时间及降低并发症发生率,具临床推广和应用价值。
