Ventrogluteal injection site

The child should be in the prone position on the parent/caregiver's lap or the clinic table with the arms tucked against their chest and the legs dangling towards the floor. The knee and hip should be turned inward to relax the muscle. The injection site should be completely exposed. Identify the following anatomic markers: anterior superior iliac spine (ASIS), the greater trochanter of the femur, and the iliac crest.
(A) For infants and small children: Place the web between the index and middle finger over the greater trochanter, the index finger on the ASIS, and the middle finger on the iliac crest. The injection site is in the center of this triangle.
(B) For larger children, adolescents, and adults: Place the palm over the greater trochanter with the thumb pointing towards the umbilicus, the index finger pointing toward the ASIS, and the middle finger pointing toward the iliac crest, forming a "V" outlining the ventrogluteal triangle. The injection site is in the center of this triangle.
