Knowledge about the variable course of the perforating arteries near the body of the femur is essential during surgical procedures (e.g., percutaneous cerclage wiring, plate osteosynthesis, Ilizarov technique). Our aims were to determine the number of perforating arteries, and to identify safe zones along the body of the femur within which perforating arteries are unlikely to pass toward the back of the thigh. The number of perforating arteries was determined in both legs of 100 formalin-fixed anatomic specimens of both sexes. The level of passage of perforating arteries near the body of the femur was measured in reference to a line from the anterior superior iliac spine to the medial femoral condyle. In each leg, two to seven perforating arteries were present. In 64% of legs, at least one artery divided into two to four branches before entering the back of the thigh. Thus, the total number of branches passing near the body of the femur varied between two to nine. Perforating arteries passed to the back of the thigh at every level between 14.0 and 36.5 cm from the anterior superior iliac spine (16-39% of the leg length). Within this distance, no safe zones along the body of the femur could be identified. The present study shows the high variability regarding number and course of the perforating arteries. Surgeons can be faced with an artery at every level on the posteromedial aspect of the body of the femur between 14.0 and 36.5 cm distally to the anterior superior iliac spine. Clin.

有关股骨体附近穿支动脉的多变性的知识，对于手术过程（例如经皮环扎钢丝、钢板接骨术、伊利扎罗夫技术）至关重要。我们的目的是确定穿支动脉的数量，并确定股骨体上不太可能向大腿后侧穿过的安全区域。我们在 100 具男女福尔马林固定的解剖标本的双腿上确定了穿支动脉的数量。测量了股骨体附近穿支动脉的通过位置，参考从髂前上棘到股骨内侧髁的线。在每条腿上，有 2 到 7 条穿支动脉。在 64%的腿中，至少有一条动脉在进入大腿后侧之前分为两到四个分支。因此，穿过股骨体附近的分支总数在 2 到 9 之间变化。穿支动脉在距髂前上棘 14.0 到 36.5cm 的范围内的每个水平都通向大腿后侧（占腿长的 16-39%）。在这个距离内，无法确定股骨体上的安全区域。本研究显示了穿支动脉数量和走行的高度变异性。外科医生可能会在距髂前上棘 14.0 到 36.5cm 远的股骨体后内侧的每个水平上遇到动脉。临床解剖学 33:507-515, 2020。©2019 年 Wiley Periodicals, Inc.
