12/10/2023 0 Comments Tib fib fracture ankle![]() Generally, traumatic tibio-fubular fracture can be suspected as one of the common causes of peroneal neuropathy, but the mechanism of injury is not clearly identified 9 and further investigation is required. 8 According to electodiagnostic findings, types of peroneal neuropathy are reported as conduction block, axonal loss or mixed axonal loss/conduction block and the axonal loss type is the most common, reaching 60% of the entire peroneal neuropathies. These electrodiagnostic findings are closely related with the degree of damage and prognosis, and those resulted by stimulating distal portion of the lesion are different according to the duration from the onset of the nerve damage. Therefore, an electrodiagnostic study is used to make the diagnosis. It is very difficult when a patient complains of atypical symptoms. 6, 7 However, limitations always exists in differential diagnosis by means of only clinical symptoms and physical findings. 5Ĭlinically, peroneal neuropathy can be suspected when patients complain of foot drop or sensory change of dorsum of their foot, but the differential diagnosis is needed to rule out L4, 5 radiculopathies caused by the herniated nucleus pulposus of the lumbar spine, lumbosacral plexopathy or sciatic neuropathy in which a peroneal division is predominantly damaged. 3, 4 However, the peroneal nerve can be injured anywhere along its course of the leg such as the calf, ankle or foot. ![]() It is well known that peroneal neuropathy is the most common mononeuropathy in the lower limb 1, 2 and it is vulnerable to damage around the fibular head because of the anatomical position between the peroneal nerve and fibula when it winds around the fibular head.
