Question

The nerve most apt to be affected during an injection in the buttocks is the?

1) Sciatic nerve
2) Femoral nerve
3) Obturator nerve
4) Peroneal nerve

Answer 1

The sciatic nerve is most vulnerable to injury during an injection in the buttocks, being the longest and thickest nerve in the body running from the sacral plexus across the hip and gluteal region.

Step-by-step explanation:

The nerve most susceptible to injury during an injection in the buttocks is the sciatic nerve. This systemic nerve from the sacral plexus is a combination of the tibial and fibular nerves and extends across the hip joint and gluteal region into the upper posterior leg. In contrast, the femoral nerve supplies the anterior leg, the obturator nerve is typically less exposed in this region, and the peroneal nerve (a branch of the sciatic nerve) is located further down the leg. The sciatic nerve is the longest and thickest nerve in the body and, if injured, can result in a painful condition known as sciatica, which is due to inflammation or compression of the sciatic nerve or any of the spinal nerves that contribute to it.
