UNASSIGNED: Computer searches of PubMed, Cochrane Library, Embase, China National Knowledge Infrastructure (CNKI), China Biology Medicine (CBM), VIP, and Wanfang digital journals were performed, and the timeframe for the searches was from the establishment of each database to July 2023 for each of the databases. Meta-analysis was performed using RevMan 5.4 software provided by the Cochrane Library, and the review process was registered in the PROSPERO database.
UNASSIGNED: A total of ten studies were included for statistical analysis. One randomised controlled study and nine retrospective cohort studies with a total of 563 patients were included. The double-plate group was superior to the single-plate group in terms of knee mobility at 6 months postoperatively, overall postoperative complications, and the rate of healing of knee deformity. However, it increased the operation time and intraoperative bleeding, and the difference between the two groups was statistically significant (P < 0.05). There was no significant difference between the two groups in terms of excellent knee function rate, fracture healing time, plate fracture, postoperative infection, delayed fracture healing, and non-union (P ≥ 0.05).
UNASSIGNED: Double plate fixation for comminuted fractures of the distal femur can improve knee mobility at 6 months postoperatively, reduce overall postoperative complications, and decrease the incidence of malunion healing. However, it increases operative time and bleeding. Randomised studies are needed to provide strong evidence in the future.
■PubMed的计算机搜索,科克伦图书馆,Embase,中国国家知识基础设施(CNKI),中国生物医学(CBM),VIP,和万方数字期刊进行了表演,搜索的时间范围是从每个数据库的建立到2023年7月。Meta分析采用CochraneLibrary提供的RevMan5.4软件,审查过程已在PROSPERO数据库中注册。
■共纳入10项研究进行统计分析。纳入了一项随机对照研究和9项回顾性队列研究,共563例患者。双板组术后6个月膝关节活动度优于单板组,术后总并发症,以及膝关节畸形的愈合率。然而,它增加了手术时间和术中出血,两组比较差异有统计学意义(P<0.05)。两组在膝关节功能优良率方面无显著差异,骨折愈合时间,钢板断裂,术后感染,骨折延迟愈合,不愈合(P≥0.05)。
■双钢板内固定治疗股骨远端粉碎性骨折可改善术后6个月的膝关节活动度,减少整体术后并发症,并降低畸形愈合的发生率。然而,它增加了手术时间和出血。未来需要随机研究来提供强有力的证据。
