Our aim is to investigate the etiological factors and electrophysiological findings. of patients with sciatic nerve injury.
Materials and Methods: In the study, the files of the patients who referred to our electromyography (EMG) laboratory at January 2010-August 2013 were retrospectively investigated. Patients whose nerve conduction study and needle EMG were made with standard techniques were included to the study. Age, sex, etiology and history data of the cases from the files were obtained.
Results: A total of 3225 patients were screened retrospectively. The number of cases admitted with the preliminary diagnosis of sciatic nerve injury was 144 and ultimately sciatic nerve lesion was diagnosed in 50 patients. The ages of patients were between 7-88; 79.6% of patients were male and 20.4% female. Among the etiological factors, femoral fractures ranked first (38%) and intramuscular injections were second (20%). In all cases peroneal nerve injury was detected, however there was no damage of tibial nerve in 14% of the cases. All the patients with tibial nerve lesion was accompanied by the peroneal nerve injury. Also 38% of peroneal nerve injury and 18% of tibial nerve lesions were total. Fracture etiology identified as the most frequent cause with 50% ratio.
Conclusion: Etiologic evaluation and electrophysiological studies has an importanat role for the management of sciatic neuropathy in terms of early diagnosis, optimal treatment and timing.
