Percutaneous radiofrequency destruction of the obturator nerve for treatment of pain caused by coxarthrosis.

Pain and restriction of movements in the hip joint due to coxarthrosis are common causes of patients' visits to their doctors. During the past few years, endoprosthetic surgery has been the most common surgical method for the treatment of this disease. Endoprosthetic operation is contraindicated for some patients in view of their excessive body weight or the presence of concurrent somatic diseases. In order to eliminate pain due to coxarthrosis, we have developed a new operation--percutaneous radiofrequency destruction of the obturator nerve--carried out at the point of its exit from the small pelvis through the obturator canal.
