“…Despite lack of conclusive evidence with respect to the number of nutrient foramina of femur, the fixed location of femoral dominant nutrient foramina on the posterior and medial aspects in the mid‐third of femur is presumably related to the requirements for continuous blood supply to the group of thigh muscles involved in the upright posture and bipedal gait, which are inserted in this region (Kizilkanat, Boyan, Ozsahin, Soames, & Oguz, 2007; Polguj, Bliźniewska, Jędrzejewski, Majos, & Topol, 2013; Santolini et al, 2014; Sołtysiak, 2015; Theodorou, Theodorou, & Resnick, 2006). More blood supply is critical to repair microfractures that are caused by the mechanical loading factors (Hu, Nelson, Snelling, & Seymour, 2018). The principal source of nourishment is via large calibre nutrient arteries originating from the perforating branches of the profunda femoris artery that passes through the nutrient foramen (Kawasaki, Kinose, Kato, Sakai, & Ichimura, 2019).…”
