Nerve | Site of compression | Symptoms | Signs | Additional features |
---|---|---|---|---|
Lateral cutaneous nerve (L2-3) | Under the inguinal ligament or against the ASIS | Neuropathic pain or paraesthesia lateral thigh, often worse with standing or walking | sensory loss lateral thigh | Associated with prolonged hip flexion (lithotomy) |
Femoral (L2-4) | Under the inguinal ligament or against the ASIS | Altered sensation in the femoral distribution, difficulty with climbing stairs | sensory loss in nerve distribution, knee extension weakness, decreased patellar reflex | Associated with prolonged hip flexion, bilateral in 25%. |
Obturator (L2-4) | Lateral wall of lesser pelvis | Groin pain and difficulty walking | Sensory loss inner thigh, weakness of hip adduction and internal rotation | bilateral in 25%, commonly associated with femoral nerve injury |
Lumbosacral plexus (L4-S3) | Posterior pelvic brim against the sacral ala | Abnormal sensation in the lumbosacral distribution. Tripping due to foot drop | Sensory loss lateral aspect of the leg and dorsum of the foot, weakness of dorsiflexion and eversion | Usually unilateral |

Common peroneal (L4-5, S1-2) | Head of fibula | Tripping due to foot drop | Sensory loss in nerve distribution, weakness of dorsiflexion and eversion | Associated with poor lithotomy positioning |
