In this study, our aim was to examine the relationship between the arthroplasty surgeons' experience level and their aptitude to adjust the cable tension to the value recommended by the manufacturer when asked to provide fixation with cables in artificial bones that underwent extended trochanteric osteotomy (ETO).
A custom-made cable tensioning device with a microvoltmeter was used to measure the tension values in Newtons (N). An ETO was performed on 4 artificial femur bones. Surgeons at various levels of experience attending the IX National Arthroplasty Congress were asked to fix the osteotomized fragment using 1.7-mm cables and the tensioning device. The participants' demographic and experience data were investigated and recorded. The surgeons with different level of experience repeated the tensioning test 3 times and the average of these measurements were recorded.
In 19 (35.2%) of the 54 participants, the force applied to the cable was found to be greater than the 490.33 N (50 kg) value recommended by the manufacturer. No statistically significant difference was determined between the surgeon's years of experience, the number of cases, and the number of cables used and the tension applied over the recommended maximum value ( = .475, = .312, and = .691, respectively).
No significant relationship was found between the arthroplasty surgeon's level of experience and the adjustment of the cable with the correct tension level. For this reason, we believe that the use of tensioning devices with calibrated tension gauges by orthopedic surgeons would help in reducing the number of complications that may occur due to the cable.
在本研究中，我们的目的是探讨关节置换外科医生的经验水平与他们在被要求使用缆线固定接受大转子延长截骨术（ETO）的人工骨时，将缆线张力调整至制造商推荐值的能力之间的关系。
使用带有微伏计的定制缆线张紧装置来测量以牛顿（N）为单位的张力值。对4根人工股骨进行了ETO。邀请参加第九届全国关节置换大会的不同经验水平的外科医生使用1.7毫米缆线和张紧装置固定截骨片段。调查并记录参与者的人口统计学和经验数据。不同经验水平的外科医生重复进行3次张紧测试，并记录这些测量值的平均值。
在54名参与者中，有19名（35.2%）施加在缆线上的力大于制造商推荐的490.33 N（50 kg）值。在外科医生的经验年限、病例数、使用的缆线数量与超过推荐最大值施加的张力之间未确定有统计学显著差异（分别为 = 0.475， = 0.312， = 0.691）。
未发现关节置换外科医生的经验水平与将缆线调整至正确张力水平之间存在显著关系。因此，我们认为骨科医生使用带有校准张力计的张紧装置将有助于减少因缆线可能发生的并发症数量。
