| 目的：探讨 G 型臂 X 线机辅助经皮微创置钉在股骨颈骨折空心钉固定术中的应用价值。方法：回顾性收集 64 例采用经皮空心钉固定治疗的成人股骨颈骨折患者的资料。其中 33 例术中采用 G 型臂 X 线机透视下辅助置钉，为 G 臂组； 31 例术中采用 C 型臂 X 线机透视下辅助置钉，为 C 臂组。采用 Harris 评分评估髋关节功能情况，比较 2 组术中操作 X 线机次数、手术时间、术后住院时间、末次随访时疼痛视觉模拟评分及 Harris 评分。结果：2 组手术均顺利完成，G 臂组解剖复位 31 例，功能复位 2 例；C 臂组解剖复位 28 例，功能复位 3 例。64 例获得随访，平均随访（5.7±0.6）个月。G 臂组术中操作X 线机次数（t = 6.287，P = 0.000）、手术时间（t = 6.482，P =0.000）少于C 臂组（P<0.05）；2 组术后住院时间（t=0.568， P=0.571）、末次随访时疼痛视觉模拟评分（t=0.530，P=0.597）及 Harris 评分（t=0.714，P=0.477）差异均无统计学意义（P>0.05）。结论：股骨颈骨折空心钉固定术中采用 G 型臂 X 线机辅助置钉，具有中术操作X 线机次数少、手术时间短的优点，可取得满意治疗效果。 |

| Abstract: |
| Objective To investigate the value of G-arm X-ray machine assisted percutaneous minimally invasive screw fixation in cannulated screws of femoral neck fractures. Methods The adult femoral neck fractures ( 64 cases) treated with percutaneous cannulated screws were retrospectively collected. Thirty-three cases assisted by ?uoroscopy of G-arm X-ray machine in the placement of percutaneous cannulated screws were recorded as the G-arm group. Thirty-one cases assisted by ?uoroscopy of C-arm X-ray machine in the placement of percutaneous cannulated screws were recorded as the C-arm group. Harris score was used to evaluate the hip function. The intraoperative operating X-ray machine times, operative time, postoperative hospital stay, pain visual analogue score and Harris score at the last follow-up were compared. Results Both group' s operations were successfully completed. The G-arm group had 31 cases of anatomical reduction, 2 cases of functional reduction, while the C-arm group had 28 cases of anatomical reduction and 3 cases of functional reduction. All patients were followed up for an average of ( 5 . 7 ± 0 . 6 ) months. In the G-arm group, the intraoperative operating X-ray machine times (t=6.287, P=0.000) and operation time (t=6.482, P=0.000) were less than those in the C-arm group (P < 0. 05). There was no signi?cant difference in the postoperative hospital stay (t =0.568, P = 0 . 571 ), pain visual analogue scale (t =0.530, P = 0 . 597 ) and Harris score (t =0.714, P = 0 . 477 ) at the last follow-up between the two groups (P >0.05). Conclusion The use of G-arm X-ray machine assisted the placement during cannulated screws ?xation for femoral neck fractures has the advantages of fewer intraoperative operating X-ray machine times and shorter operative time, and can achieve satisfactory therapeutic results. |
