Purpose: The spine is an important source of pain and disability, affecting two thirds of adults at some time in their lives. Treatment in these patients is mainly conservative medical management, based on medication, physical therapy, behavioral management, and psychotherapy, surgery being limited to elective cases with neurologic deficits. This study was carried out to evaluate the efficacy of percutaneous nucleoplasty in patients affected by painful diskal protrusions and contained herniations. Methods: From February 2004 to October 2005, 72 patients (48 men, 24 women; mean age 48 years) affected by lumbar disk herniation were treated with nucleoplasty coblation. All patients were evaluated clinically and with radiography and MRI in order to confirm the presence of lumbalgic and/or sciatalgic pain, in the absence of major neurologic deficit and with lack of response after 6 weeks of conservative management. Results: Average preprocedural pain level for all patients was 8.2 (on a visual analog scale of 1 to 10), while the average pain level at 12 months follow-up was 4.1. At the 1 year evaluation, 79% of patients demonstrated a statistically significant improvement in numeric pain scores (p < 0.01): 17% (12 patients) were completely satisfied with complete resolution of symptoms, and 62% (43 patients) obtained a good result. Conclusion: Our data indicate that nucleoplasty coblation is a promising treatment option for patients with symptomatic disk protrusion and herniation who present with lumbalgic and/or sciatalgic pain, have failed conservative therapies, and are not considered candidates for open surgery.Key words: Diskogenic back pain-Interventional radiology-Lumbar pain-Nucleoplasty-SpineThe spine is an important source of pain, suffering, and disability, affecting two thirds of adults at some time in their lives [1,2]. In these individuals the treatment remains mainly conservative, including medication, physical therapy, behavioral management, and psychotherapy.In recent years the general trend in spinal surgery has been toward reduction and minimalization. In fact minimally invasive techniques for the treatment of degenerative pathology of the spine have come to be preferred by surgeons since the destructive effect on bony structures is eliminated and scar formation is greatly reduced [3]. Nucleoplasty is new minimally invasive therapeutic option that has been used for spinal procedures since July 2000.The following study was carried out to evaluate the efficacy of nucleoplasty, performed under local anesthesia, in patients affected by diskal protrusions and contained herniations.
