股骨颈动力交叉钉系统治疗中青年PauwelsⅡ型Ⅲ型股骨颈骨折的临床价值分析

To Analyze the Clinical Value of Femoral Neck Power Cross-nailing System in Treating Pauwels TypeⅡand TypeⅢFemoral Neck Fractures in Young and Middle-aged People

目的探究股骨颈动力交叉钉系统治疗中青年PauwelsⅡ型Ⅲ型股骨颈骨折的临床价值。方法随机选取2020年1月—2022年7月于三明市中西医结合医院接受治疗的155例中青年PauwelsⅡ型Ⅲ型股骨颈骨折患者为研究对象,通过随机数表法分为对照组(n=80)及治疗组(n=75),分别行空心螺钉内固定治疗、股骨颈动力交叉钉系统。对临床指标、并发症发生情况展开观察。结果两组患者住院时间对比,差异无统计学意义(P>0.05)。治疗组手术时间[(45.57±4.44)min]短于对照组、骨折愈合时间[(3.61±0.87)个月]早于对照组、Harris髋关节功能评分[(92.49±5.51)分]高于对照组、股骨颈缩短长度[(4.91±1.05)mm]短于对照组,差异有统计学意义(t=38.498、5.657、4.304、7.786,P均<0.05)。对照组术中出血量[(17.32±5.21)mL]少于治疗组、切口总长度[(3.51±0.82)cm]短于治疗组,差异有统计学意义(t=11.380、6.032,P均<0.05)。治疗组并发症发生率(2.67%)低于对照组,差异有统计学意义(χ^(2)=4.326,P<0.05)。结论空心螺钉内固定治疗以及股骨颈动力交叉钉系统治疗中青年PauwelsⅡ型Ⅲ型股骨颈骨折在住院时间不具有明显差异,空心螺钉内固定术可减少患者术中出血量并缩短切口总长度,而股骨颈动力交叉钉系统则可缩短手术时间、骨折愈合时间、股骨颈缩短长度、提高Harris评分、降低并发症发生率。

Objective To investigate the clinical value of femoral neck power cross-nailing system for the treatment of Pauwels typeⅡand typeⅢfemoral neck fractures in young and middle-aged people.Methods 155 cases of young and middle-aged patients with PauwelsⅡtypeⅢfemoral neck fracture treated in Sanming Integrated Medical Hospital from January 2020 to July 2022 were randomly selected as study subjects,and were divided into the control group(n=80)and the treatment group(n=75)by the method of randomized number table,and underwent internal fixation of the hollow screw and femoral neck power cross-nailing system,respectively.The clinical indexes and the occurrence of complications were compared between the two groups.Results There was no statistically significant difference in the comparison of hospitalization time between the two groups(P>0.05).In the treatment group,the operation time[(45.57±4.44)min]was shorter than that of the control group,the fracture healing time[(3.61±0.87)months]was earlier than that of the control group,the Harris Hip Function Score[(92.49±5.51)points]was higher than that of the control group,and the femoral neck shortening length[(4.91±1.05)mm]was shorter than that of the control group,and the differences were statistically significant(t=38.498,5.657,4.304,7.786,all P<0.05).Intraoperative bleeding[(17.32±5.21)mL]in the control group was less than that in the treatment group,and the total length of incision[(3.51±0.82)cm]was shorter than that in the treatment group,and the differences were statistically significant(t=11.380,6.032,both P<0.05).The complication rate of the treatment group(2.67%)was lower than that of the control group,and the difference was statistically significant(χ^(2)=4.326,P<0.05).Conclusion Internal fixation with hollow screws as well as femoral neck power cross-nailing system for the treatment of young and middle-aged Pauwels typeⅡand typeⅢfemoral neck fractures did not have significant differences in hospitalization time.Internal fixation with hollow screws reduces intraoperative bleeding and shortens the total length of the incision,while the femoral neck power cross�nailing system reduces operative time,fracture healing time,femoral neck shortening length,improves the Harris score,and reduces the complication rate.
