摘要:

文题释义:
PauwelsⅢ型股骨颈骨折:PauwelsⅢ型骨折冠状面骨折线和髋臼上缘角度>50°,属于股骨颈垂直骨折,具有较大的剪切力,多见于中年人,发生于高能量创伤之后,术后易发生骨折不愈合、缺血坏死、内固定失效等。
股骨颈内侧支撑钢板:固定于股骨颈骨折线前下方,能够施加一个抗垂直股骨颈骨折剪切力的支撑力,从而能够降低股骨颈骨折不愈合及股骨头坏死等并发症的发生率。

背景:近几年有学者认为采用股骨颈内侧支撑钢板结合空心螺钉内固定治疗PauwelsⅢ型股骨颈骨折,能够降低股骨颈骨折不愈合、股骨头坏死等并发症的发生率,但对于这种治疗方式在临床上能否加速骨折的愈合、减少股骨头坏死等尚存在争议。

目的:Meta分析评估股骨内侧支撑钢板结合空心螺钉和单纯空心螺钉内固定治疗PauwelsⅢ型股骨颈骨折的疗效差异。

方法:利用 Cochrane图书馆、PubMed、万方医学网、中国知网、中国期刊全文数据库搜索并收集采用股骨内侧支撑钢板结合空心螺钉内固定和单纯空心螺钉内固定治疗PauwelsⅢ型股骨颈骨折的临床对照试验,分别由2名评价者独立对纳入的研究进行质量评价、数据提取并进行互相核对,最后运用 RevMan 5.3软件对相关数据进行Meta分析。

结果与结论:①经过筛选最终纳入5篇相关临床试验,其中包括4篇随机对照试验和1篇回顾性队列研究,总共243例PauwelsⅢ型股骨颈骨折患者;②Meta分析结果显示:与单纯空心螺钉内固定相比,股骨内侧支撑钢板结合空心螺钉内固定治疗的手术时间较长[MD=23.19,95%CI(8.32,38.06),P=0.002]、术中出血量较多[MD=83.48,95%CI(32.08,134.89),P=0.001]、愈合时间较短[MD=-1.56,95%CI(-1.89,-1.24),P < 0.000 01]、并发症发生率较低[RD=-0.07,95%CI(-0.11,-0.02),P=0.003]、髋关节Harris评分较高[MD=7.39,95%CI(3.18,11.60),P=0.000 6];两者髋关节功能优良率比较差异无显著性意义[OR=1.29,95%CI(0.02,74.86),P=0.90];③结果表明与单纯空心螺钉内固定相比,支撑钢板结合空心螺钉治疗PauwelsⅢ型股骨颈骨折可缩短愈合时间、减少术后并发症、提高术后Harris评分。

Abstract:

BACKGROUND: In recent years, some scholars have proposed the use of medial femoral neck support plate combined with cannulated screw internal fixation to treat Pauwels type III femoral neck fracture. This method can reduce the incidence of complications such as nonunion of the femoral neck fracture and femoral head necrosis. However, it is still controversial whether this treatment can accelerate fracture healing and reduce femoral head necrosis in clinic.

OBJECTIVE: Meta-analysis was performed to evaluate the difference in the efficacy of femoral medial support plate combined with cannulated screw internal fixation and simple cannulated screw internal fixation for the treatment of Pauwels type III femoral neck fracture.

METHODS: Cochrane Library, PubMed, Wanfang Medical Network, China National Knowledge Infrastructure, and China Journal Full-text Database were used to search for and collect the clinical Chinese and English literature of the trials regarding Pauwels III femoral neck fracture treated with internal femoral support plate combined with cannulated screw internal fixation and simple cannulated screw internal fixation. Two evaluators independently conducted quality evaluation, data extraction and cross-checking of the included studies, and finally performed meta-analysis on the collected data using RevMan 5.3 software.

RESULTS AND CONCLUSION: (1) After screening, 5 related clinical trials were included, including 4 randomized controlled trials and 1 retrospective cohort study, for a total of 243 patients with Pauwels III femoral neck fracture. (2) Meta-analysis results showed that compared with simple cannulated internal fixation, operation time was longer [MD=23.19, 95%CI(8.32, 38.06), P=0.002], intraoperative blood loss was more [MD=83.48, 95%CI(32.08, 134.89), P=0.001], and healing time was shorter [MD=-1.56, 95%CI(-1.89, -1.24), P < 0.000 01], the incidence of complications was lower [RD=-0.07, 95%CI(-0.11, -0.02), P=0.003], and hip Harris score was higher [MD=7.39, 95%CI(3.18, 11.60), P=0.000 6] in the femoral medial support plate combined with cannulated screw internal fixation. However, there was no statistically significant difference in the excellent and good rate of hip function between the two treatments [OR=1.29, 95%CI(0.02, 74.86), P=0.90]. (3) In the treatment of Pauwels type III femoral neck fracture, compared with simple cannulated nail fixation, cannulated screws combined with medial support plate can shorten healing time, reduce postoperative complications and elevate postoperative Harris score.
