Why is this relevant?: As mentioned in the article: Gluteus Maximus: Superficial & Deep Fibers, cadaver dissections have revealed deep fibers of the gluteus maximus that only invest in the sacrum and ilium (that do not cross the hip). Further, a large majority of the cross-sectional area of the gluteus maximus can be attributed to fibers that cross both the sacrum and hip, implying that the gluteus maximus may have a special role in stabilization of the sacroiliac joint (SIJ). This study takes the next step by investigating the amount of force these fibers can generate and the resulting compressive force on the SIJ, so that we may hypothesize the contribution of the gluteus maximus to SIJ stabilization.
