Fate of sciatic nerve palsy following hip arthroplasty

Sciatic nerve palsy is a rare complication that occur after total hip arthroplasty but clinically this can result in significant functional deficit. The previous literature suggests most of the sciatic nerve palsy symptom to improve after a few weeks to a few months but in the real clinical setting, the result may vary and the symptom maybe significantly prolonged and some may not fully recover to the original state. Therefore, the current study aims assessed the fate of the patients who developed sciatic nerve palsy from hip arthroplasty operation. The authors have also looked at potential risk factors for poor outcome. This is the first case series in the Korean literature and we are reporting the result with the literature review.
