Which nerve is most commonly injured during the harvest of bone from the anterior hip?

• A. Femoral nerve
• B. Lateral cutaneous branch of iliohypogastric nerve
• C. Obturator nerve
• D. Inferior gluteal nerve

Answer: (B)

The lateral cutaneous branch of the iliohypogastric nerve is commonly injured during the harvest of bone from the anterior hip due to its anatomical location. This nerve provides sensory innervation to the skin of the lateral abdominal wall and trajectory that is often in proximity to surgical sites in the hip and iliac area. When bone is harvested from the iliac crest, the surgical approach involves incisions and dissection that can inadvertently damage nearby structures, including this nerve. Although the femoral nerve, obturator nerve, and inferior gluteal nerve are also important in the anatomy and function of the hip region, they are less frequently affected during the specific procedure of iliac bone harvesting. The femoral nerve is situated more medially, the obturator nerve is located in a deeper position within the pelvis, and the inferior gluteal nerve is typically further posterior. Hence, the potential for injury to the lateral cutaneous branch of the iliohypogastric nerve is heightened due to its route and proximity to the surgical field in this context.
