Gluteus gluteus maximus m. Gluteus maximus
Unbends the hip in the hip joint, turning it slightly outward. By cutting the upper part of the gluteus major muscle, the thigh is retracted. The lower part of the large gluteus muscle, contracting, helps to pull the bent femur against a large load. Gluteal muscles contract in the case when the balance of the center of gravity of the body (walking and standing on uneven soil, etc.) favorable for equilibrium is disturbed. Especially significant is the function of these mice when climbing a mountain, running, climbing a ladder, moving from a sitting position to a standing position, jumping, etc. When walking on a straight line on a flat surface, and when standing calmly, both large gluteal muscles are relaxed. Thus, without the involvement of the gluteus maximus muscle, one can not run or walk on an inclined plane, one can not rise from the chair without the help of hands. As in all places of greatest friction, between the large gluteus muscle and the large trochanter there is a large mucous bag.
Beginning: iliac bone (area behind Linea glutaea posterior). Sacrum, coccyx, Lig. Sacrotuberal
Attachment: fascia latae, Tuberositas glutaea femoris
Innervation: spinal nerves L5-S2 - sacral plexus - n gluteus inferior
Diagnostics: Trigger zones are most often localized: at the point of attachment of the muscle to the sacrum, over the ischial tubercle (the most frequent site of injury), in the most medial and inferior muscle fibers, attached mainly to the coccyx. Trigger zones in this muscle are available for palpation, local convulsive responses are often clearly visible. The patient lies on the side of the muscle being examined upward, the hip is slightly bent. Trigger zones of the first two (localizations are investigated by plane palpation, for which the thumb is drawn across the fibers.) The search and examination of the last trigger zones is carried out by the tick-like palpation: the muscle fibers are compressed between the thumb and the remaining fingers.
Reflex pain is usually localized in the gluteal region. The pain from the trigger zones located at the place of attachment to the sacrum, is localized around the interannual gap with the capture of the region of the sacroiliac joint. The reflected pain from the trigger zones located above the ischial tubercle, is localized throughout the gluteus muscle, extending deep into the gluteal region, imitating the lesion of the deep gluteus muscles. This pain never grabs the anal region and the coccyx. Trigger zones in the medial and lower muscle fibers are often the cause of cocciogeny, which can also be caused by the presence of trigger zones in the coccygeal muscle.
