Vastus Lateralis Intramuscular Injection
The vastus lateralis muscle is a common site for
intramuscular injection. To inject, first locate the greater trochanter of the
femur. The top border of the vastus lateralis muscle can be found a hand width
below the groin. The bottom border of the vasus lateralis muscle is found a
hand above the knee. The side borders are from the mid anterior thigh to the
mid lateral thigh. Squeezing the muscle before injection increases the
thickness and depth of the muscle and avoids nerve injuries. Make sure you do
not advance the needle deep to touch the bone. Aspirate before you inject.
