Final answer:
Compression of the lateral femoral cutaneous nerve leads to meralgia paresthetica, and should not be confused with sciatica, which affects the sciatic nerve.
Step-by-step explanation:
Compression of the lateral femoral cutaneous nerve results in meralgia paresthetica, a condition characterized by tingling, numbness, and burning pain in the outer thigh. This is distinct from sciatica, which involves the sciatic nerve and results in pain that radiates along the sciatic nerve from the lower back, through the hip and buttocks, and down the leg. The sciatic nerve is a systemic nerve from the sacral plexus that is a combination of the tibial and fibular nerves and extends across the hip joint and gluteal region into the upper posterior leg. Meralgia paresthetica specifically involves the lateral femoral cutaneous nerve, not the sciatic or other nerves listed in the options.
