[Nerve lesions following total hip replacement and other hip-joint operations].

Nerve lesions occurred in 17 patients who had undergone hip-joint operations (especially total replacement). The femoral nerve was most commonly affected, followed by sciatic and gluteal nerves, with combined pareses in six. As differential diagnosis from pseudoparesis is not always possible, electromyography should be performed in all cases. Stretching and/or squeezing are the most important causes. The operation results are significantly impaired by such nerve lesions. However, long-term results are usually satisfactory in the majority of cases. Early diagnosis and treatment are important in ensuring good therapeutic results.
