Lower Limb Muscles

Taylor et al. (2015) describe an accessory muscle in a female cadaver that was surrounded by a fascial sheath. It arose from the deep fibers of the inferior portion of gluteus maximus and converged into a tendon that had a contribution from the iliotibial tract. The tendon inserted onto the proximal aspect of the femur lateral to the intertrochanteric crest just superior to the gluteal tuberosity.

The anterior of the capsule of the hip joint is attached to the intertrochanteric line, but posteriorly the capsule does not reach as far as the intertrochanteric crest, being attached halfway along the back of the femoral neck. Fracture of the neck disrupts blood vessels that supply the head of the femur.

A tough fibrous capsule encloses the joint; this is under maximum tension when the hip is extended. Superiorly and posteriorly it attaches directly to bone immediately peripheral to the labrum. Inferiorly and anteriorly it attaches to bone, the outer labral surface and the transverse acetabular ligament. Distally, the capsule attaches anteriorly to the intertrochanteric line, and posteriorly it attaches approximately 1.25 cm proximal to the intertrochanteric crest. Therefore the posterolateral one-third of the femoral neck is extracapsular. The capsule consists of two sets of fibres – the circular zona orbicularis and longitudinal fibres. The iliofemoral, pubofemoral and ischiofemoral ligaments reinforce the capsule (Fig. 17.1). The ligamentum teres is intra-articular and is attached proximally to the margins of the acetabular fossa and the transverse ligament. Distally it attaches to the femoral head at the fovea, carrying the artery of the ligamentumteres. Synovial membrane covers the intraarticular portion of the femoral neck and is reflected onto the internal surface of the capsule and the external surface of the ligamentum teres.

QF along with the other deep hip external rotators are stabilizers of the hip and primarily contribute to providing support during hip movements, thus acting as “postural” muscles (Semciw et al. 2015). The QF arises from the lateral margin of the ischial tuberosity and inserts into the intertrochanteric crest (Yoo et al. 2015). However, several variations in their proximal and distal attachment sites have been described by different anatomy books, with a paucity of description in the literature (Yoo et al. 2015). It is interesting to note that anatomical anomalies such as complete unilateral or bilateral absence of QF have been reported in case studies (Yoo et al. 2015). It is unknown if the patient in this case report had any anatomical anomalies, thus forming a limitation of physical examination and of this case report. Also, the exact cause of MPS of the QF is unknown in this patient.
