Introduction: Femoral nerve block, when used solely or as a supplement to general anaesthesia, provides anaesthesia and analgesia to the anterior thigh. In spite of its established benefits, femoral nerve block is still underutilized in Nigeria. Our objective was to study the dimension of femoral nerve at the level of the inguinal ligament and inguinal crease using a cadaveric model; no such data exists in Nigeria. Materials and Methods: Using 7 adult human cadavers (6 males and 1 female), the depth and thickness of the femoral nerve were measured at the levels of inguinal ligament and inquineal crease. The spatial relationship of femoral nerve to the surrounding structures was also observed. Results: The study showed a significant wider thickness and shorter depth of the femoral nerve at the level of inquinal crease relative to inguinal ligament. Conclusion: We Nigerians are unavailable, the inguinal crease level where the femoral nerve is more superficial and wider in thickness would be the landmark of choice compared to the inguinal ligament level.
