文题释义:
解剖型锁定加压钢板:在临床中广泛用于治疗股骨转子下长段粉碎性骨折,术中采用解剖型钢板,其近端呈扁平状扩张部可完全覆盖大转子外部,不同开口方向的螺钉可牢固固定股骨头,抗拔出能力较强,可有效防止修复后产生旋转现象。
防旋型髓内钉:是治疗股骨转子下长段粉碎性骨折常用治疗方法,在术中采用螺旋刀片锁定替代螺钉固定,刀片进入骨质时不需要扩孔并能起到较好填压作用,锁定后的刀片可与骨质紧密锚合,可有效防止松动退出现象产生。
 
摘要
背景:目前股骨近端解剖型锁定加压钢板和防旋型髓内钉内固定是治疗股骨转子下长段粉碎性骨折常用的修复方法,但关于两种植入物的疗效及安全性的差异比较相关研究较少。
目的:试验旨在比较股骨近端解剖型锁定加压钢板和防旋型髓内钉内固定修复股骨转子下长段粉碎性骨折的有效性及安全性差异,以筛选最佳的植入物治疗方案。
方法:方案设计为前瞻性、单中心、非随机对照临床研究。将纳入三亚市中医院的股骨转子下长段粉碎性骨折患者180例,按修复方法不同分为加压钢板组和髓内钉组,每组90例,分别采用解剖型锁定加压钢板和防旋型髓内钉内固定修复。随访时间为2,10个月。试验对象招募和资料收集时间为2019-06-30/2020-06-30,结果分析时间为2020-07-01/30,试验完成时间为2022-08-01。试验经三亚市中医院医学伦理委员会批准[审批时间:2013-03-15,审批号:(2013)第(02)号]。研究符合世界医学会制定的《赫尔辛基宣言》的要求;参与者家属或本人均对试验方案和过程知情同意,并签署知情同意书。试验已在中国临床试验注册中心注册(注册号:ChiCTR1900021251),注册时间:2019-02-03,方案版本号1.0。
结果与结论:①研究的主要结局指标:以修复后10个月髋关节Harris评分优良率评估修复后髋关节功能恢复情况;②研究的次要结局指标:修复前、修复后2个月髋关节Harris评分优良率,术中失血量、手术时间、切口长度、住院时间、骨折愈合时间,修复前、修复后2,10个月髋关节X射线形态,修复后2,10个月不良发应发生率。③课题组于前期(2013年2月至2016年2月)纳入了此类患者80例,包括加压钢板组和髓内钉组各40例,随访10个月发现,髓内钉组术中失血量、手术时间、切口长度、住院时间及骨折愈合时间均少于加压钢板组(P < 0.05);髓内钉组优良率高于加压钢板组(P < 0.05);髓内钉组不良反应发生率(10.0%)稍低于加压钢板组(12.5%),但差异无显著性意义(P > 0.05),前期80例患者的小样本试验结果证明,防旋型髓内钉置入内固定股骨转子下长段粉碎性骨折的有效性及安全性较好。试验希望证实,相比与解剖型锁定加压钢板,防旋型髓内钉置入内固定股骨转子下长段粉碎性骨折会取得修复后更好的髋关节功能恢复效果,且安全性能好。

Abstract:

BACKGROUND: The proximal femoral anatomical locking compression plate and proximal femoral nail antirotation device are commonly used in the treatment of long-segment comminuted subtrochanteric fractures of the femur. However, few studies have evaluated the difference in efficacy and safety between these two implants.

OBJECTIVE: To compare the efficacy and safety of the proximal femoral anatomical locking compression plate versus proximal femoral nail antirotation in the treatment of long-segment comminuted subtrochanteric fractures of the femur, and to identify the optimal implant treatment plan.
METHODS: This prospective, single-center, non-randomized controlled clinical trial will include 180 patients with long-segment comminuted subtrochanteric fractures of the femur from Sanya Traditional Chinese Medicine Hospital, China. The patients will be equally divided into a locking compression plate group and a proximal femoral nail antirotation group (n=90). All patients will be followed up at 2 and 10 months postoperatively. Patient recruitment and data collection will begin on 30 June 2019 and end on 30 June 2020. Analysis of the results will be performed from 1 to 30 July 2020. This study will be scheduled to end on 1 August 2022. This study was approved by the Medical Ethics Committee of Sanya Traditional Chinese Medicine Hospital in China on 15 March 2013 (approval No. (2013) (02)). This study will be performed in strict accordance with the Declaration of Helsinki formulated by the World Medical Association. Written informed consent regarding the study protocol and surgery procedure will be obtained from the participants’ family members or the participants themselves. This trial had been registered in the Chinese Clinical Trial Registry (registration number: ChiCTR1900021251) on 3 February 2019. Protocol version (1.0).
RESULTS AND CONCLUSION: (1) The primary outcome measure is the rate of excellent and good Harris hip scores at 10 months postoperatively; this rate will be used to evaluate the recovery of hip function after repair. (2) The secondary outcome measures are the rate of excellent and good Harris hip scores preoperatively and 2 months postoperatively, intraoperative blood loss, operation time, incision length, hospital stay, fracture healing time, hip morphology on radiographs preoperatively and 2 months postoperatively, and incidence of adverse events 2 and 10 months postoperatively. (3) Our pilot study involved 80 patients with long-segment comminuted subtrochanteric fractures of the femur from February 2013 to February 2016 (locking compression plate group, n=40; proximal femoral nail antirotation group, n=40). The 10-month follow-up results showed that the intraoperative blood loss, operation time, incision length, hospital stay, and fracture healing time were lower in the proximal femoral nail antirotation group than in the locking compression plate group (P < 0.05). The rate of an excellent and good Harris hip score was higher in the proximal femoral nail antirotation group than in the locking compression plate group (P < 0.05). The complication rate was lower in the proximal femoral nail antirotation group (10.0%) than in the locking compression plate group (12.5%) (P > 0.05). These pilot study results in 80 patients verified higher efficacy and safety of proximal femoral nail antirotation than locking compression plate fixation in the treatment of long-segment comminuted subtrochanteric fractures of the femur. The results of the present study will provide evidence indicating whether proximal femoral nail antirotation in the treatment of long-segment comminuted subtrochanteric fractures of the femur can facilitate better recovery of hip function and higher safety than anatomical locking compression plate fixation.
