A 67-year-old patient has been given a course of antibiotics by gluteal intramuscular injections after a major abdominal surgery.To avoid damaging the sciatic nerve during an injection, the needle should be inseed into which of the following areas?

To avoid damaging the sciatic nerve during an intramuscular injection, the clinician should inse the needle in the upper lateral quadrant of the gluteal region. The inseed needle in the lower medial quadrant may damage the pudendal and sciatic nerves. The inseed needle midway between the ischial tuberosity and the lesser trochanter may damage the sciatic and posterior femoral cutaneous nerves on the quadratus femoris. The inseed needle over the sacrospinous ligament may damage the pudendal nerve and vessels.
