This results in increased degrees of knee flexion in order to clear the ground. Weaknesses in gluteus medius often result in a Trendelenburg sign, an abnormal gait cycle where the hip of the swinging leg drops down, rather than raises up. It is also referred to as a ball and socket joint and is surrounded by muscles, Iliopsoas is sometimes classified as two muscles, Iliacus and Psoas major, with Iliacus arising from the Ilium and Psoas from the vertebrae. The gluteus maximus extends, laterally rotates, abducts (upper fibers), and adducts (lower fibers) the thigh at the hip joint. Figure 37. This blog post article is an overview of the motions of the joints of the pelvis: the paired left and right sacroiliac joints and the symphysis pubis joint.

Anterior view of the right iliopsoas muscle. It functions best as a hip flexor when the knee is flexed. For example, when flexing the thigh at the hip joint to lift the foot up into the air anteriorly, the brain usually co-orders the pelvis to drop into posterior tilt because this facilitates bringing the foot even higher. However, some pelvic floor musculature (coccygeus and levator ani) are partially accessible from the outside, inferior to the piriformis. Hip Flexors. The articular cartilage is kept slick by fluid made in the synovial membrane (joint lining).

The Tensor Fasciae Latae (TFL) is a small muscle on the outside of the hip. Other pelvic muscles, such as the psoas major and iliacus, serve as flexors of the trunk and thigh at the hip joint and laterally rotate the hip as well. Pectineus is positioned between the Iliopsoas and Adductor Longus muscles and is part of the short adductor group with adductors brevis and longus. Pelvic floor muscle spasm in women is called vaginismus. This means it flexes the hip or trunk & tilts the pelvis anteriorly like iliacus. Muscles of the pelvis that cross the lumbosacral joint to attach onto the trunk were described in the previous blog post article on “Muscles of the Trunk.” Their reverse action pelvic motions occur when their superior trunk attachment is fixed, and the pelvic attachment moves instead. Before doing that, it is important to first place muscles of the pelvis into their three major categories. Manual Therapy for the Low Back and Pelvis – A Clinical Orthopedic Approach (2015).

(B) Deep. As with the discussion of these muscles from the perspective of the trunk, understanding pelvic rotation motions by these muscles requires visualizing the horizontal component to the fiber direction of the muscles. The various muscles which attach to or cover the hip joint generate the hip’s movement. The flexors are located anteriorly, extensors posteriorly, abductors laterally, and adductors medially. These muscles primarily rotate the hip externally. The sciatic nerve passes underneath this muscle on its route down to the posterior thigh. Extension – the reverse of flexion, moving the leg down and backwards. These are the gluteus maximus, gluteus medius, gluteus minimus, and tensor fasciae latae. It attaches inferiorly (underneath/below) to the long thick strip of fascia, known as the iliotibial band (ITB).
