Rotator cuff tears are one of the common etiologies of shoulder pain. Rotator cuff repair is recommended for a patient who failed conservative treatment. Proper knowledge of the rotator cuff footprint is needed in restoring correct anatomy during the repair. The size of the footprint is important in determining the kind of repair.
This study aimed to define the average measurements of the rotator cuff footprint on the humerus in Filipino cadavers.
This is a descriptive, cross-sectional study of preserved human cadaver upper extremity specimens. We measured the length, width, and shape of the supraspinatus, infraspinatus, subscapularis, and teres minor.
We obtained 27 upper extremity specimens. The median age of the source cadavers was 50.5 years with the equal male-to-female distribution. The mean measurement of the supraspinatus is 22.92 mm in length and 10.17 mm in width. The shape of the supraspinatus was found to be trapezoidal. The infraspinatus length was found to be 17.20 mm and the width at 10.72 mm. Its shape was found to be trapezoidal. The teres minor length was measured at 15.15 mm and the width at 11.04 mm. The shape was mostly trapezoidal but some were triangular. Finally, the subscapularis length was 17.68 mm while the width was 11.26 mm. The shape was trapezoidal or comma-shaped.
The average measurement of the rotator cuff footprint was found to be smaller in our study than reported in terms of length and width. The footprint shape was similar to the studies reported.
肩袖撕裂是肩部疼痛的常见病因之一。对于保守治疗失败的患者，建议进行肩袖修复。在修复过程中恢复正确的解剖结构需要对肩袖足迹有充分的了解。足迹的大小对于确定修复方式很重要。
本研究旨在确定菲律宾尸体肱骨上肩袖足迹的平均测量值。
这是一项对保存的人体尸体上肢标本进行的描述性横断面研究。我们测量了冈上肌、冈下肌、肩胛下肌和小圆肌的长度、宽度和形状。
我们获得了27个上肢标本。来源尸体的中位年龄为50.5岁，男女分布均等。冈上肌的平均测量长度为22.92毫米，宽度为10.17毫米。发现冈上肌的形状为梯形。冈下肌长度为17.20毫米，宽度为10.72毫米。其形状为梯形。小圆肌长度测量为15.15毫米，宽度为11.04毫米。形状大多为梯形，但有些为三角形。最后，肩胛下肌长度为17.68毫米，宽度为11.26毫米。形状为梯形或逗号形。
在我们的研究中，发现肩袖足迹的平均测量值在长度和宽度方面比报道的要小。足迹形状与报道的研究相似。
