BACKGROUND/AIM: The supratrochlear foramen (STF) is an important variation in the lower end of the humerus where the septum separating the coronoid and olecranon fossa is perforated. There are no studies in the literature on the STF of the Jining population. This study will make a contribution to anatomy and anthropology by adding new data.
STF was studied in detail in 262 adult dried humeri of unknown sex and age. The topographical anatomy of the STF was studied, morphometric measurements were taken, and the specimens were photographed with a digital camera.
The prevalence of the STF was 10.3%, with 18 cases on the left side and 9 cases on the right side. The STF occurred in 4 shapes: oval, 19 cases; round, 4 cases; triangular, 2 cases; and rectangular, 2 cases. The mean transverse diameter of STF was 4.47 mm and 3.26 mm on the left and right sides, respectively; the mean vertical diameter of STF was 5.07 mm and 3.56 mm on the left and right sides, respectively; and the average surface area of STF was 13.1 mm2 and 18.43 mm2 on the left and right sides, respectively.
The STF of the Jining population was more common on the left side, with oval being the most common shape. The two sides did not show any statistically significant differences. The findings of this study may be of clinical significance to surgeons and osteologists and may have anthropological or forensic importance.
背景/目的：滑车上孔（STF）是肱骨下端的一个重要变异，此处分隔冠状突和鹰嘴窝的隔被穿孔。文献中尚无关于济宁人群 STF 的研究。本研究将通过提供新的数据为解剖学和人类学做出贡献。
详细研究了 262 具未知性别和年龄的成人干肱骨中的 STF。研究了 STF 的局部解剖学，进行了形态测量，并使用数码相机对标本进行了拍摄。
STF 的患病率为 10.3%，左侧 18 例，右侧 9 例。STF 有 4 种形状：椭圆形，19 例；圆形，4 例；三角形，2 例；和矩形，2 例。STF 的平均横径为左侧 4.47 毫米和右侧 3.26 毫米；STF 的平均垂直直径为左侧 5.07 毫米和右侧 3.56 毫米；STF 的平均表面积为左侧 13.1 平方毫米和右侧 18.43 平方毫米。
济宁人群的 STF 更常见于左侧，以椭圆形最为常见。两侧之间没有统计学上的显著差异。本研究的发现可能对外科医生和骨骼学家具有临床意义，并且可能具有人类学或法医学意义。
