Abstract：
UNASSIGNED: Acetabular fractures are among the most challenging injuries in traumatology. The complex anatomy usually requires extensive surgical approaches baring the risk for iatrogenic damage to surrounding neurovascular structures. As a viable alternative, minimally invasive endoscopic techniques have emerged during the recent years. This paper reports on the feasibility of different coupling mechanisms for a novel suprapectineal plate especially designed for minimally invasive acetabular surgery.
UNASSIGNED: A total number of 34 participants contributed to the present study, who differed in their arthroscopic and surgical experience. A laparoscopic model was used to compare four different coupling mechanisms by the number of failed attempts, the time required for plate fixation, the influence of surgical experience as well as the learning success for each individual coupling mechanism. Moreover, the feasibility of each mechanism was evaluated by a questionnaire.
UNASSIGNED: The results demonstrate that plates employing grooved and pressure-sliding coupling mechanisms exhibit fewer failed attempts and reduce trial times, especially in contrast to sole sliding mechanisms. Furthermore, our study revealed that proficiency in endoscopic procedures significantly influenced the outcome. Notably, the subjective evaluation of the participants show that the pressure base and pressure-slide base plate designs are the most supportive and feasible designs.
UNASSIGNED: In summary, the present study evaluates for the first-time different plate and coupling designs for minimal-invasive surgery, indicating a superior feasibility for plates with a grooved and pressure-sliding mechanism.

摘要：
■髋臼骨折是创伤学中最具挑战性的损伤之一。复杂的解剖结构通常需要广泛的手术方法，以免对周围的神经血管结构造成医源性损伤。作为一种可行的选择,近年来出现了微创内镜技术。本文报道了专门为微创髋臼手术设计的新型外皮上钢板的不同耦合机制的可行性。
■共有34名参与者参与了本研究，他们的关节镜和手术经验不同。腹腔镜模型用于通过失败的尝试次数比较四种不同的耦合机制，钢板固定所需的时间，手术经验以及学习成功对每个个体耦合机制的影响。此外，通过问卷评估每种机制的可行性.
■结果表明，采用开槽和压力滑动耦合机构的板减少了失败的尝试，并减少了试验时间，特别是在对比唯一的滑动机构。此外，我们的研究显示,熟练掌握内镜操作对结局有显著影响.值得注意的是,参与者的主观评价表明，压力底座和压力滑动底板设计是最支持和可行的设计。
■总之，本研究首次评估了微创手术的不同钢板和联轴器设计，表明具有开槽和压力滑动机构的板具有优越的可行性。
