Which intramuscular injection site minimizes risk due to proximity to the sciatic nerve?

• A. Deltoid
• B. Gluteal Sites
• C. Vastus lateralis
• D. Dorsogluteal

Answer: (B)

Minimizing risk from the sciatic nerve means choosing a site where the injection path stays away from that nerve. The sciatic nerve runs deep in the posterior gluteal region, so injections in the dorsogluteal area carry a higher chance of nerve contact if the needle is too deep or misdirected. Gluteal sites, particularly when using the ventrogluteal approach, provide a broad, well-muscled area and a trajectory that avoids the nerve and major vessels. This placement reduces the likelihood of nerve injury compared to injections aimed at the dorsogluteal region, making gluteal sites the safer choice for minimizing proximity-related risk to the sciatic nerve.
