The location of the gluteal injection is located in the gluteus maximus muscle, because the gluteus maximus muscle is thicker compared to other gluteal muscle tissues and is far away from the sciatic nerve and large blood vessel tissues, which can avoid injuring the nerves and blood vessels to the greatest extent and reduce the muscle pain, spasm and other undesirable symptoms that may be brought about by the muscle injection. For determining the location of gluteus maximus, the following methods can be adopted for positioning. First, the cross positioning method, you can keep the patient sitting flat, select the starting position of the gluteal fissure of the caudate of the patient’s hip, draw a horizontal line in each of the two major directions to the left and right, and then select a quarter of the location above the vertical horizontal line from the apex of the iliac spine for muscle injection operation. Second, by means of the connecting line method, a third of the site on the line is selected as the injection point on the horizontal vertical line from the top of the caudal hip to the anterior superior iliac spine.
