摘要:

文题释义:

股骨转子间骨折:是指骨折线累及大转子跟小转子之间的连线,也就是转子间线之间的骨折。股骨转子间骨折常见于老年人,为老年人走路摔伤时髋部着地造成的一种暴力性骨折。该骨折手术风险极高,死亡率较高,被称为“人生的最后一次骨折”。
股骨近端防旋髓内钉内固定:股骨近端防旋髓内钉由螺旋刀片、主钉、锁定螺钉组成,主钉设计与股骨近端解剖相匹配,6°外展角便于自大转子间进入,操作方便,对股骨头血运影响较小,空心钉主钉置入方便,主钉远端有一定弹性,避免应力集中,主钉及螺旋刀片有不同长度,适合不同身高的股骨解剖,螺旋刀片的设计具有抗旋转及抗切出的作用,螺旋刀片具有宽大的表面积,通过局部打压股骨松质骨,具有较高的锚合力。

摘要
背景:老年股骨转子间骨折患者常伴多种内科合并症及明显骨质疏松,给治疗带来较大挑战。股骨近端防旋髓内钉与InterTAN均为常用髓内钉内固定系统,如何为不同病情和骨折类型的患者精准选择最合适的治疗方案尚缺乏足够的循证依据。
目的:对比带双螺纹钉的近端股骨髓内钉系统(InterTAN)与股骨近端防旋髓内钉内固定治疗老年股骨转子间骨折的临床效果及并发症差异。
方法:采用前瞻性随机对照设计,纳入118例符合纳入标准的老年股骨转子间骨折患者,随机分为2组,股骨近端防旋髓内钉组59例行股骨近端防旋髓内钉内固定,InterTAN组59例行InterTAN髓内钉内固定。围术期记录手术时间、术中出血量、透视次数、住院天数等指标;术后于1,3,6,12个月进行随访,通过Harris髋关节功能评分及影像学检查评估骨折愈合率、内固定稳定性及并发症发生情况。

结果与结论:①股骨近端防旋髓内钉组手术时间、出血量、透视次数均显著低于InterTAN组(P < 0.001),两组住院天数相比差异无显著性意义(P > 0.05);②术后12个月,两组患者骨折愈合率相近(P > 0.05);术后12个月时InterTAN组内固定不稳定率显著降低(P < 0.05),Harris疼痛、功能及关节活动度评分均明显优于股骨近端防旋髓内钉组(P < 0.05);两组并发症总发生率相比差异无显著性意义(P > 0.05);③提示股骨近端防旋髓内钉在围术期创伤方面具备一定优势,而InterTAN在术后1年随访时的固定稳定性及功能恢复上更具潜在价值,临床应结合患者病情和骨折类型综合选择内固定系统。

Abstract: BACKGROUND: Elderly patients with intertrochanteric fractures often have multiple medical comorbidities and significant osteoporosis, posing considerable challenges for treatment. Proximal femoral nail anti-rotation and InterTAN are both commonly used intramedullary fixation systems. However, there remains insufficient evidence regarding the optimal selection of fixation systems for patients with different medical conditions and fracture types.
OBJECTIVE: To compare the clinical outcomes and complication differences between integrated compression screw and lag screw intertrochanteric nail (InterTAN) and proximal femoral nail anti-rotation in the treatment of elderly patients with intertrochanteric fractures.  
METHODS: A prospective randomized controlled trial was conducted. A total of 118 elderly patients with intertrochanteric fractures who met the inclusion criteria were enrolled. Patients were randomly divided into groups. The proximal femoral nail anti-rotation group (59 cases) underwent internal fixation with proximal femoral nail anti-rotation, and the InterTAN group (59 cases) underwent internal fixation with InterTAN. Perioperative parameters, including operation time, intraoperative blood loss, fluoroscopy frequency, and hospital stay, were recorded. Follow-up assessments were conducted at 1, 3, 6, and 12 months postoperatively. The fracture healing rate, internal fixation stability, and complications were evaluated using Harris hip scores and imaging examinations.  
RESULTS AND CONCLUSION: (1) Operation time, intraoperative blood loss, and fluoroscopy frequency in the proximal femoral nail anti-rotation group were significantly lower than those in the InterTAN group (P < 0.001). No significant difference was found in hospital stay (P > 0.05). (2) The fracture healing rates were similar between the two groups at 12-month follow-up (P > 0.05). At 12 months, the incidence of instability was significantly lower in the InterTAN group (P < 0.05). Harris scores in terms of pain, function, and joint mobility in the InterTAN group were significantly superior to those in the proximal femoral nail anti-rotation group (P < 0.05). There was no significant difference in overall complication rates between the two groups (P > 0.05). (3) These results indicate that proximal femoral nail anti-rotation has certain advantages in reducing perioperative trauma, whereas InterTAN demonstrates greater potential value in terms of fixation stability and functional recovery at the 1-year follow-up. Clinical selection of internal fixation systems should be based comprehensively on the patient's condition and fracture type.
