Background:
The sciatic and peroneal nerves are the most frequently injured in lower extremities, followed by tibial and femoral nerves. The aim of this study is to evaluate the functional results of acute nerve grafting in traumatic sciatic nerve injuries.
Methods:
A total of 9 patients with sciatic nerve defect were treated with primary nerve grafting. The mean age was 31.7 years. The etiologic factors were gunshot wounds, traffic accident, and penetrating trauma.
Results:
All of the patients had sciatic nerve defects ranging from 3.4 to 13.6 cm. The follow-up period ranged between 25 and 84 months. The tibial nerve motor function was "good" or "very good" (M3-M4) in 5 patients (55.6%). The plantar flexion was not sufficient for the rest of the patients. The peroneal nerve motor function was also "good" and "very good" in 3 patients (33.3%).
Conclusion:
The functional results of the acute nerve grafting of the sciatic nerve within the first week after the injury are poorer than reported in the related literature. This protocol should only be applied to select patients who have adequate soft tissue coverage and healthy nerve endings.
