When an intramuscular injection is given in the anterior aspect of the thigh then the injection may be in the vastus lateralis muscle or rectus femoris because on the anterior aspect of the thigh there is vastus lateralis and rectus femoris both are present but vastus lateralis is slightly laterally present and rectus is present in mid of the anterior aspect, so , it can be rectus femoris or can be vastus lateralis.

Rectus femoris and Vastus lateralis muscle both are used for the intramuscular injection in the infants but vastus lateralis is used more commonly.
