目的

研究股骨近端防旋髓内钉(PFNA)与动力髋螺钉(DHS)内固定治疗稳定型股骨粗隆间骨折的临床效果及并发症分析。

方法

纳入60例Evans分型为Ⅰ、Ⅱ型的股骨粗隆间骨折为研究对象,均为南方科技大学医院2017年1月至2019年1月收治的病例,按随机数字表法将其分为DHS组(n=30)和PFNA组(n =30)。2组患者均给予常规术前准备及术后处理,DHS组采用DHS内固定治疗,PFNA组采用PFNA内固定治疗,对出院患者进行半年的随访。应用卡方检验和t检验比较2组手术指标(术后并发症、术后骨折愈合指标、术后Harris评分)的差异。

结果

PFNA组的手术时间、出血量、切口长度均小于DHS组(t=3.029、9.416、8.945,均为P <0.01),患者出院半年后PFNA组的骨折愈合时间、负重时间均短于DHS组(t=2.118、2.327,均为P <0.05),患者出院半年后PFNA组与DHS组患者Harris总评分均较术前升高,且PFNA组高于DHS组,差异具有统计学意义(t=2.485,P <0.05)。PFNA组与DHS组术后并发症均为10%。

结论

PFNA和DHS均可以治疗股骨粗隆间骨折患者,其中PFNA内固定较DHS有明显优势,具有手术时间短、出血小、创伤小、愈合率高等优点,且显著提高肢体功能。

Objective

To explore the clinical efficacy and analyse the complications of proximal femoral nail antirotation(PFNA) and dynamic hip screw(DHS) in the internal fixation for intertrochanteric fractures of femur.

Methods

Sixty cases of intertrochanteric fracture of femur were included in this study. They were all treated in the Affiliated Hospital of Southern Universtiy of Science and Technology from January 2017 to January 2019. They were divided randomly into DHS group (n=30) and PFNA group (n=30) according to random number table method. Both groups were given routine preoperative preparation and postoperative treatment, DHS group were treated with DHS internal fixation, PFNA group were treated with PFNA internal fixation. The discharged patients were followed up for half a year. The difference of surgical indicators between the two groups, and the complications of the two groups were compared. Half a year after discharge, the fracture healing indicators and the Harris scores were also compared. Chi-square test and t test were used for analysis.

Results

The operation time, bleeding volume and incision length of PFNA group were shorter than or less than those of DHS group (t=3.029, 9.416, 8.945, all P<0.01). Half a year after discharge, the fracture healing time and weight-bearing time of PFNA group were shorter than those of DHS group (t=2.118, 3.227, both P<0.05). The total Harris scores of PFNA group and DHS group were higher than those of DHS group half a year after discharge, and PFNA group were higher than that of DHS group, the difference was statistically significant (t=2.485, P<0.05). Postoperative complications were both 10% in PFNA group and DHS group.

Conclusions

PFNA and DHS can treat intertrochanteric fractures of femur. PFNA internal fixation has obvious advantages over DHS, which shows shorter operation time, less bleeding, less trauma, higher healing rate and higher Harris score and improves the limb function.
