Medication administered via intramuscular injection is not subject to the first-pass metabolism effect which affects oral medications. Common sites for intramuscular injections include the deltoid muscle of the upper arm and the gluteal muscle of the buttock. In infants, the vastus lateralis muscle of the thigh is commonly used. The injection ...
The gluteus maximus arises from the posterior gluteal line of the inner upper ilium, and the rough portion of bone including the crest, immediately above and behind it; from the posterior surface of the lower part of the sacrum and the side of the coccyx; from the aponeurosis of the erector spinae (lumbodorsal fascia), the sacrotuberous ligament, and the fascia covering the gluteus medius.
The buttocks are formed by the masses of the gluteal muscles or "glutes" (the gluteus maximus muscle and the gluteus medius muscle) superimposed by a layer of fat. The superior aspect of the buttock ends at the iliac crest , and the lower aspect is outlined by the horizontal gluteal crease .
The anterior gluteal line is the middle curved gluteal line on the hip bone. It is the longest of the three gluteal lines, begins at the iliac crest , about 4 cm. behind its anterior extremity, and, taking a curved direction downward and backward, ends at the upper part of the greater sciatic notch.
The gluteal muscles include the gluteus maximus, gluteus medius, gluteus minimus, and tensor fasciae latae.They cover the lateral surface of the ilium.The gluteus maximus, which forms most of the muscle of the buttocks, originates primarily on the ilium and sacrum and inserts on the gluteal tuberosity of the femur as well as the iliotibial tract, a tract of strong fibrous tissue that runs ...
The most common cause is an iatrogenic injury during hip surgery or an intramuscular injection. Lesions of the inferior gluteal nerve occur through iatrogenic injuries like surgery, trauma, hernias, or pelvic tumors. This condition may result in a functional deficiency of the gluteus maximus muscle, leading to difficulties climbing the stairs ...
Subcutaneous injection sites. Commonly used injection sites include: [3]: 723 The outer area of the upper arm. The abdomen, avoiding a 2-inch circle around the navel. The front of the thigh, between 4 inches from the top of the thigh and 4 inches above the knee. The upper back. The upper area of the buttock, just behind the hip bone.
The functional purpose of the buttocks musculature is to establish a stable gait (balanced walk) for the person who requires the surgical correction of either a defect or a deformity of the gluteal region; therefore, the restoration of anatomic functionality is the therapeutic consideration that determines which gluteoplasty procedure will effectively correct the damaged muscles of the buttocks.
