Nerve Injuries conditions

Common Fibular (Peroneal) Nerve Injury (L4-S2)Common Fibular (Peroneal) Nerve Injury (L4-S2) involves damage to the nerve causing foot drop, sensory loss over the lateral leg and dorsum of the foot, often from trauma or compression.Femoral Nerve Injury (L2-L4)Femoral nerve injury (L2-L4) causes weakness in hip flexion and knee extension with sensory loss over the anterior thigh and medial leg, often from pelvic trauma.Genitofemoral Nerve Injury (L1-L2)Genitofemoral nerve injury (L1-L2) causes sensory loss in the upper anterior thigh and genital region, often from pelvic surgery or trauma.Iliohypogastric Nerve Injury (T12-L1)Iliohypogastric nerve injury (T12-L1) causes lower abdominal and groin pain with sensory loss, often from abdominal surgery or trauma affecting motor and sensory fibers.Inferior Gluteal Nerve Injury (L5-S2)Inferior Gluteal Nerve Injury (L5-S2) involves damage to the nerve supplying the gluteus maximus, causing weakness in hip extension and difficulty rising from sitting.Lateral Femoral Cutaneous Nerve Injury (L2-L3)Lateral femoral cutaneous nerve injury (L2-L3) causes meralgia paresthetica with numbness and burning pain over the anterolateral thigh due to nerve entrapment.Nerve Injury (C5-C6 Roots)Nerve injury of the C5-C6 roots involves damage to the upper brachial plexus causing weakness in shoulder abduction, external rotation, and elbow flexion with sensory loss.Nerve Injury (C8-T1 Roots)Nerve Injury C8-T1 Roots involves damage to the lower brachial plexus causing weakness in hand muscles and sensory loss along the medial arm and forearm.Nerve Injury (Distal Median Nerve)Nerve Injury (Distal Median Nerve) involves damage to the median nerve at the wrist, causing sensory loss and motor deficits in the hand's lateral digits and thenar muscles.Nerve Injury (Distal Ulnar Nerve)Distal ulnar nerve injury causes sensory loss in the medial hand and motor deficits like claw hand due to impaired intrinsic hand muscles.Nerve Injury (Long Thoracic Nerve, Roots C5-C7)Nerve Injury of the Long Thoracic Nerve (Roots C5-C7) causes scapular winging and shoulder weakness due to serratus anterior muscle paralysis.Nerve Injury (Lower Trunk and Subclavian Vessels)Injury to the lower trunk of the brachial plexus and subclavian vessels causes claw hand and vascular compromise, often from trauma or thoracic outlet syndrome.Nerve Injury (Proximal Median Nerve)Nerve Injury (Proximal Median Nerve) involves damage to the median nerve near the elbow causing forearm and hand motor deficits and sensory loss in the lateral palm.Nerve Injury (Proximal Ulnar Nerve)Nerve Injury (Proximal Ulnar Nerve) involves damage to the ulnar nerve near the elbow causing sensory loss and weakness in the hand and forearm muscles.Obturator Nerve Injury (L2-L4)Obturator nerve injury (L2-L4) involves damage to the nerve causing medial thigh pain, weakness in thigh adduction, and sensory loss over the medial thigh.Pudendal Nerve Injury (S2-S4)Pudendal nerve injury (S2-S4) involves damage to the nerve supplying the perineum, causing pain, numbness, or dysfunction in the genital and anal regions.Sciatic Nerve Injury (L4-S3)Sciatic nerve injury (L4-S3) causes lower limb pain, weakness, and sensory loss, often from trauma or compression affecting motor and sensory branches.Superior Gluteal Nerve Injury (L4-S1)Superior Gluteal Nerve Injury (L4-S1) involves damage to the nerve supplying hip abductors, causing weakness, Trendelenburg gait, and difficulty with hip stabilization.Tibial Nerve Injury (L4-S3)Tibial nerve injury (L4-S3) causes foot plantarflexion weakness and loss of sensation on the sole, often from trauma or compression near the knee.
