This study was designed to compare the pull-out strength of simple suture stitches in human supraspinatus tendons with respect to the position of the rotator cable.
Fifty-four tests were performed on 6 intact, human supraspinatus tendons, to assess the cutout strength of a simple suture configuration in different positions; medial to, lateral to, or within the rotator cable. Tendon thickness was measured and correlated for each positioned suture.
Suture positioning lateral to or in the rotator cable showed significantly lower suture retention properties compared with positioning the suture medial to the cable (p = 0.002). In all tested specimens, the central stitch in the row medial to the rotator cable provided the optimum retention properties (mean: 191 N; SD: ± 44; p < 0.01), even after correcting for tendon thickness.
This study shows that it is desirable to identify the rotator cable and to pass sutures just medial to it, close to the middle of the tendon, which provided highest possible suture retention properties.
本研究旨在比较肩袖冈上肌腱内单纯缝线的抽出强度与旋转带电缆的位置关系。
对 6 个完整的人体冈上肌腱进行了 54 次测试，以评估不同位置（旋转带电缆内、外侧或电缆内）的简单缝线结构的切出强度。测量了肌腱的厚度，并对每个定位缝线进行了相关性分析。
与将缝线定位在电缆内侧相比，将缝线定位在电缆外侧或电缆内显示出明显较低的缝线保留性能（p = 0.002）。在所有测试的标本中，位于旋转带电缆内侧的行中央缝线提供了最佳的保留性能（平均：191N；SD：±44；p<0.01），即使在纠正肌腱厚度后也是如此。
本研究表明，理想情况下应识别旋转带电缆，并将缝线穿过其内侧，靠近肌腱的中部，以提供尽可能高的缝线保留性能。
