Designing for Lower Torso and Leg Anatomy
Published in Karen L. LaBat, Karen S. Ryan, Human Body, 2019
Three large thigh adductors (adductor magnus, adductor longus, and adductor brevis) pull the thighs together and fill out the medial thigh. They originate on the pubic bone and insert on the femur. To feel their action: (1) sit in a chair, (2) place a something like a soccer ball between your knees, (3) place one hand over one medial (inner) thigh, and (4) squeeze the object to feel the muscles contract. The bulk of the inner thigh can completely fill the space between the upper thighs and influences the curve of the proximal pants inseam. The mass of the quadriceps, hamstrings, and adductors all contribute to the fullness needed in the upper pants leg.
Functional Anatomy and Biomechanics

Musculus adductor brevis is situated under the pectineus muscle. Insertion: The origin is on the frontal surface of the inferior ramus of the pubis. The distal insertion is on the lower two-third of the pectineal line and the upper half of the linea aspera. Action: It is an adductor of the femur and assists flexing the femur at the hip joint. Innervations are given by the obturator nerve (L2-L4).

During gait analysis, a gait is divided into eight gait events, including of heel strike, foot flat, midstance, heel off, toe off, acceleration, midswing, and deceleration (Bai and Shang 2010). There are two main methods for muscle modeling. This article mainly uses linear muscles to replace the physical model of muscles to establish the musculoskeletal system model. The default coordinate system and orientation of each minutia (Zhao et al. 2016) is the same as that of the CT machine. And totally 11 muscle models were constructed, including the Adductor longus, Adductor magnus, Adductor brevis, Vastus medialis, Vastus lateralis, Iliopsoas, Gluteus minimus, Gluteus medius, Gluteus maximus, Gastrocnemius lateralis, and Gastrocnemius medialis (Bai and Shang 2010; Ali Banijamali et al. 2015). The model of the musculoskeletal linear hip joint is shown in Figure 3 and the muscle force on the femur is shown in Table 2.
