Sartorius may be absent (Macalister 1875; Bergman et al. 1988; du Plessis and Loukas 2016; Standring 2016). This muscle can vary in its course as it descends in the anterior thigh (Macalister 1875). Sartorius may be partially or fully split into two longitudinal portions, and the additional portion can have a separate insertion onto the tibia, the femur, the fascia lata, the patellar ligament, the semitendinosus tendon, or the tendon of the other sartorius portion (Hallett 1848; Macalister 1875; el-Badawi 1987; Bergman et al. 1988; du Plessis and Loukas 2016; Coban et al. 2019). This bifurcation may be confined to its origin or insertion or comprise over half of the muscle (Hallett 1848; Macalister 1875; Knott 1883b; Kedzia et al. 2011; du Plessis and Loukas 2016; Coban et al. 2019). Macalister (1875) notes that Kelch and Kyrtl observed a central tendinous intersection in sartorius. An extra head of sartorius may originate from the pubis, pectineal line, femoral sheath, below the anterior superior iliac spine, or from the inguinal ligament (Macalister 1875; Bergman et al. 1988; du Plessis and Loukas 2016; Standring 2016).
Salter's osteotomy and Dega osteotomy
Published in K. Mohan Iyer, Hip Preservation Techniques, 2019
The Sartorius muscle could usually be reflected medially with the cartilaginous iliac apophysis. If it is difficult to do so, or if more distal exposure is desired, the Sartorius is detached from the anterior superior iliac spine, its free margin is marked with whip sutures for later re-attachment, and the muscle is medially and distally reflected.
General plastic
Published in Tor Wo Chiu, Stone’s Plastic Surgery Facts, 2018
There are several described variations on the use of the sartorius muscle: Simple mobilisation without detaching origin. This has been called a ‘myoplasty’, but the use of this term is inconsistent.Detach origin and advancement of muscle – ‘transposition’.Detach origin and rotate muscle medially/internally. This sartorius ‘twist’ aims to leave the posterior medial vessels untouched and preserve the vascular supply as much as possible.

We present the case of a 55-year-old female patient with a history of breast cancer, adenomyosis of the uterus, and gastroesophageal reflux, with normal renal function, and not taking warfarin. She initially bruised the lateral area of her right thigh, which became a painful and indurated nodule with redness (Figure 1a). Gradually, she experienced severe radiating pain and numbness over her entire right lower limb and was referred to a local orthopedic hospital. The relevant medication history included agents containing activated vitamin D3 and calcium supplementation for osteoporosis. Computed tomography (CT) revealed extensive soft tissue calcification and inflammation reaching the sartorius muscle at the initial lesion site (Figure 1b). A partial excision biopsy was performed, and pathological examination revealed diffuse necrosis and calcareous deposits in the lesion.

In this study, the muscles with high activities, including gluteus maximus, semitendinosus, Rectus femoris, iliopsoas, vastus lateralis and sartorius, were analyzed, and those muscles with low activities or small muscle tissues were not taken into account. Gluteus maximus has a wide and thick quadrilateral shape, and mainly drives the extension and external rotation of the thigh. Semitendinosus is located at the back of the thigh and helps the extension of the hip joint and bending of the knee joint. Rectus femoris is located in the front of the thigh, whose main function is to extend the knee joint and bend the thigh. Iliopsoas is composed of psoas major muscle and iliacus, which is mainly responsible for the external rotation of the thigh and forward flexion of the pelvis and trunk. The sartorius is flat and banded, and is one of the longest in the leg muscles, starting from the anterior superior iliac spine, passing through the inner side of the knee joint, and finally to the inner side of the upper end of the tibia. The main function of sartorius is for the bending of the hip and knee.

In a cadaveric study by Morris et al, increased femoral torsion and acetabular version resulted in premature contact between the femoral neck and acetabulum.10 However, increased acetabular version does not imply posterior acetabular overcoverage, especially in hips with a lateralized femoral head. Therefore, the relationship between the posterior acetabular wall and center of the femoral head was utilized in the present study as a more logical contributor than acetabular version to limited HE. A limitation in the aforementioned cadaveric study was the inclusion of specimens without ligamentous or musculotendinous structures.10 The absence of an obvious osseous etiology in 35 (38%) hips with HE in our study indicates the fundamental role of musculotendinous and ligamentous structures in limiting HE. Tightness of the musculotendinous structures such as the iliopsoas, sartorius, rectus femoris, or tensor fascia lata muscle should be considered in patients with limited HE.4–6 The rectus femoris, sartorius, and tensor fascia lata muscles cross both the hip and knee joint, and the degree of knee flexion should be controlled during hip physical examination and assessment of HE. Increased terminal HE by extending the knee may indicate a contribution of one of the aforementioned musculotendinous structures in limiting HE. Long-lasting limited HE due to osseus etiologies may also lead to the subsequent tightening of anterior ligamentous and musculotendinous structures.
