Mononeuropathies are a form of peripheral neuropathy characterized by sensory disturbances and/or motor deficits in the distribution of the affected nerve. They can occur secondary to direct trauma, compression, stretch injury, ischemia, infection, or inflammatory disease. [1] In the lower extremity, peroneal neuropathy is the most common isolated mononeuropathy and the third most common mononeuropathy overall. Peroneal mononeuropathy may result in the clinical complaint of pain and sensory disturbances in the lateral lower limb and dorsal foot, and weakness of the ankle dorsiflexors and evertors. The peroneal nerve is also known as the superficial peroneal nerve and more recently the superficial fibular nerve. [2]
