【摘要】：目的:通过临床模拟的方法,测量有经验的临床医师使用小夹板技术治疗模拟肱骨干骨折时扎带捆绑的各项力学数据,并探讨数据之间的关系,为小夹板技术治疗的标准化、改进及其推广提供参考基准数据。方法:召集45名骨科临床医师依次模拟捆绑10名志愿者,通过电测法测量不同体位及功能锻炼24h后扎带的张力以及扎带对内侧夹板的压力。结果:(1)扎带的张力:不同体位及功能锻炼24h后,组内重复测量方差分析差异较大,差异有统计学意义(P0.01)。不同职称组组间方差分析结果差异无统计学意义。故推荐两组均值为临床参考值:捆绑即刻中立位扎带张力为(847.96±79.01)g;捆绑即刻屈肘握拳位扎带张力为(1 412.11±137.57)g。(2)扎带对内侧夹板压力:组间与组内方差分析结果与扎带张力相同。故同理推荐两组均值为临床参考值:捆绑即刻中立位扎带对内侧夹板压力为(692.36±63.47)g;捆绑即刻屈肘握拳位扎带张力为(1 222.67±120.37)g。(3)扎带的张力与扎带对内侧夹板压力之间关系:即刻中立位,两者呈线性相关。回归方程为:y=13.682+0.800x(y为捆绑即刻中立位的扎带对内侧夹板压力,x为捆绑即刻中立位的扎带张力)。结论:职称因素并不影响小夹板扎带捆绑的力学效果。小夹板扎带的张力与内侧夹板压力呈直线相关。
[Abstract]:Objective: to measure the mechanical data of ligation and binding in the treatment of humeral shaft fracture with small splint technique by clinical simulation, and to discuss the relationship between the data, and to standardize the treatment of small splint technique.Improve and popularize to provide reference datum.Methods: 45 orthopedic clinicians were recruited to simulate and bind 10 volunteers in turn. The tension of the band and the pressure of the band on the medial splint were measured by electrometric method after 24 hours of different posture and functional exercise.Results the tension of strapping band: after 24 hours of different posture and function exercise, the variance analysis of repeated measurement within the group was significant (P 0.01).There was no significant difference in the results of ANOVA among groups with different titles.Therefore, the mean value of the two groups was recommended as the clinical reference value: the tension of the immediate neutral band was 847.96 卤79.01 g, the tension of the band in the immediate elbow bending position was 1 412.11 卤137.57 g 路m-2) the pressure of the band to the medial splint was the same as that of the strapping band. The results of variance analysis between groups were the same as the tension of the band.There is a linear correlation between the two.The regression equation was: 1: yyyong 13.682 0.800x(y for the binding of the immediate neutral position and the pressure of the inner splint x for the binding tension of the immediate neutral position.Conclusion: professional title does not affect the mechanical effect of small splint binding.The tension of the small splint band is linearly related to the pressure of the inner splint.
