UNASSIGNED:导航技术提高了肩关节成形术中关节盂组件定位的准确性和精度。导航对底板螺钉放置的影响尚未独立研究。这项研究旨在评估和综合有关术中导航对反向全肩关节置换术中主要基板固定螺钉的长度和数量的影响的最佳科学证据。
未经批准:2022年8月,PubMed,Scopus,并访问了Embase数据库。我们分析了螺杆的购买长度,固定底板所需的螺钉数量,以及在所有临床试验中用两个螺钉固定的病例比例,比较导航与标准器械的反向肩关节置换术。在对研究的异质性进行评估之后,DerSimonian-Laird随机效应模型用于合并来自单独研究的数据。
UASSIGNED:系统搜索显示共2034篇文章。在排除重复和不相关的研究之后,来自6项试验的633例肩关节置换术被纳入分析。螺钉购买长度的合并平均差为5.839mm(95CI4.496至7。182)有利于导航(P<.001)。此外,在每个病例的螺钉数量(-0.547,95CI-0.890至-0.203,P=.002)和用两个螺钉固定的病例比例(赔率比3.18295CI1.057至9.579,P=.040)方面也发现了显著差异,有利于导航组.
UNASSIGNED:术中导航改进了底板螺钉的放置,允许更大的螺钉购买长度和更少的螺钉,以实现反向肩关节置换术期间关节盂部件的主要固定。目前尚不清楚这些改进是否会增加假体的寿命或患者的临床结果。
UNASSIGNED: Navigation technologies have improved accuracy and precision in positioning glenoid components during shoulder arthroplasty. The influence of navigation on baseplate screw placement has not been independently investigated. This study aimed to evaluate and synthesize the best scientific evidence on the influence of intraoperative navigation on the length and number of screws for primary baseplate fixation in reverse total shoulder arthroplasty procedures.
UNASSIGNED: In August 2022, PubMed, Scopus, and Embase databases were accessed. We analyzed the screw purchase length, the number of screws required for the fixation of the baseplate, and the proportion of cases fixed with two screws in all clinical trials, comparing navigation to standard instrumentation for reverse shoulder arthroplasty. Following an evaluation of the heterogeneity of the studies, DerSimonian-Laird random-effects models were utilized to merge data from separate studies.
UNASSIGNED: The systematic search revealed a total of 2034 articles. After excluding duplicates and irrelevant studies, 633 shoulder arthroplasties from 6 trials were included in the analysis. The pooled mean difference in screw purchase length was 5.839 mm (95 %CI 4.496 to 7. 182) in favor of navigation (P < .001). In addition, significant differences were also found in the number of screws per case (- 0.547, 95 %CI -0.890 to -0.203, P = .002) and in the proportion of cases fixed with two screws (Odds Ratio 3.182 95 %CI 1.057 to 9.579, P = .040) in favor of the navigation group.
UNASSIGNED: Intraoperative navigation improves the baseplate screw placement, allowing for a greater screw purchase length and fewer screws to achieve primary fixation of the glenoid component during reverse shoulder arthroplasty. It is unclear whether these improvements will increase the longevity of the prosthesis or the clinical outcomes of the patients.
