Pyelonephritis
Pyelonephritis is a common presentation to the Emergency Department. The most important consideration is renal tract imaging to rule out an obstructive cause, which can rapidly lead to severe sepsis.
Tibial nerve lesions
Tibial nerve lesions cause plantarflexion weakness, sensory loss in the sole, and can result from trauma, compartment syndrome, or systemic neuropathy
Renal colic
Renal colic (or nephrolithiasis) is an extremely common presenting problem to the Emergency Department. The immediate priority will be pain relief.
Sciatic nerve lesions
Sciatic nerve lesions cause motor loss below the knee and sensory loss in the foot and leg. Most commonly injured in the buttock, often from trauma or injection.
Obturator nerve lesions
Obturator nerve lesions cause impaired thigh adduction and medial thigh sensory loss, most often from pelvic trauma, compression, or compartment syndrome.
Femoral nerve lesions
Femoral nerve injury causes leg extension weakness, impaired hip flexion, and sensory loss over the anterior thigh and medial leg. Often traumatic in origin
Common Peroneal Nerve Lesions
Common peroneal nerve injury causes foot drop and sensory loss over the lateral leg and foot. Often due to trauma or compression near the fibular neck
Ulnar Nerve Lesions
Ulnar nerve lesions cause claw hand, sensory loss in the medial hand, and weakness of grip. Most often due to trauma, compression, or neuropathy.
Radial Nerve Lesions
Radial nerve lesions typically cause wrist drop and sensory loss over the dorsum of the hand. Commonly due to trauma, compression, or systemic disease.
Median Nerve Lesions
Median nerve lesions cause weakness in forearm pronation, wrist/finger flexion, and thumb opposition, with characteristic sensory loss in the lateral hand
Axillary Nerve Lesions
Axillary nerve lesions typically cause deltoid weakness and sensory loss over the lateral shoulder, often following shoulder trauma or dislocation.
