| Background: Peripheral nerve injuries (PNI) are relatively common pathologies in clinical practice. PNIs
are rare in the lower extremity but have worse prognosis than those in the upper extremity. Electrodiagnostic
studies could help better understanding PNIs. In this study, we aimed to evaluate the distribution
of lower extremity PNI in traumatic patients in northwest of Iran.
Methods: In this prospective study, 74 patients (62 male and 12 female with mean age of 38.39 ± 14.42
years) with possible lower or lumbosacral peripheral nerve injury were studied. Patients' demographic
information and physical examination findings were recorded. Electrodiagnostic investigations including
electromyography and Nerve Conduction Study were performed for all subjects.
Results: Common chief complaints were pain and weakness. Impairment in the sensory function was
present in 59.5% and muscle force reduction in 47.3%. PNIs were present in 23.0% and mostly were severe.
Injuries in sciatic nerve were the most common PNIs (16.2%). Electrodiagnostic studies showed radiculopathy
in 48.7% and plexopathy in 8.10% of cases. In 52 patients (70.3%), the physical examination
findings were compatible with Electrodiagnostic studies.
Conclusion: Not all patients presenting with traumatic injuries have lower extremity PNIs. Due to the
nature of the trauma and the anatomical course of the nerves, sciatic nerve is more susceptible to
traumatic injuries. |
