As a hip flexor, the pectineus is an extremely important muscle because of its involvement in the postural distortion pattern known as lower crossed syndrome. Because of the location of the pectineus medially, it is also considered to be part of the adductor group. As such, the pectineus is an excellent example of a transition muscle, being located within two functional groups.
