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 greater sciatic notch is a notch in the ilium, one of the bones that make up the human pelvis. It lies between the posterior inferior iliac spine (above), and the ischial spine (below). The sacrospinous ligament changes this notch into an opening, the greater sciatic foramen .
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 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 ...
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 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 gluteal region encompassing the buttocks, the femoral region encompassing the thigh, the popliteal region encompassing the back of the knee, the sural region encompassing the back of the lower leg, the calcaneal region encompassing the heel, the plantar region encompassing the sole of the foot. Some regions are combined into larger regions.
The ischial tuberosity (or tuberosity of the ischium, tuber ischiadicum), also known colloquially as the sit bones or sitz bones, [1] or as a pair the sitting bones, [2] is a large posterior bony protuberance on the superior ramus of the ischium. It marks the lateral boundary of the pelvic outlet.
