Analysis of disk volume before and after CT-guided intradiscal and periganglionic ozone-oxygen injection for the treatment of lumbar disk herniation.
To quantify the change in volume in herniated lumbar disk after computed tomography (CT)-guided intradiscal and periganglionic ozone-oxygen injection and to assess the effects of patient age, sex, and initial disk volume on disk volume changes. ⋯ Intradiscal administration of medical ozone is associated with a statistically significant volume reduction of the herniated lumbar disk. The volume-reduction effect of ozone correlates negatively with the patient's age and positively with initial disk volume.

Multicenter StudyStaff doses in interventional radiology: a national survey.
To present the results of occupational radiation doses investigated through a national survey promoted by the National Society of Interventional Radiology in Spain. ⋯ For under-apron and hand readings, extrapolated median values were below 30% of annual dose limits, but in the case of over-apron readings, the extrapolated median dose was higher than the newly recommended limit for the eye lens of 20 mSv per year. This study mainly highlights the need to use radiation protection tools and personal dosimeters to protect staff and monitor eye lens doses.

Case ReportsPercutaneous treatment of lumbar compression fracture with canal stenosis and neurogenic intermittent claudication: combining kyphoplasty and interspinous spacer.
Vertebral compression fractures (VCFs) can cause symptomatic spinal canal stenosis secondary to posterior wall retropulsion. This report describes four patients with VCF and lumbar stenosis secondary to posterior wall retropulsion who were treated with combined kyphoplasty and percutaneous interspinous spacer (IS) placement. ⋯ Outcomes were favorable. Combined kyphoplasty and percutaneous IS implant represents a minimally invasive, safe, and efficient option to treat VCF with symptomatic spinal stenosis.

Randomized Controlled Trial Multicenter Study Comparative StudyDoes age of fracture affect the outcome of vertebroplasty? Results from data from a prospective multicenter FDA IDE study.
To evaluate whether the age of a fracture is a variable that can identify patients for whom vertebroplasty would be most beneficial. ⋯ Results of the study showed that the age of a fracture does not independently affect the outcomes of vertebroplasty.

Comparative StudyPercutaneous vertebroplasty and kyphoplasty for pathologic vertebral fractures in the Medicare population: safer and less expensive than open surgery.
To compare cost and outcomes of surgical and percutaneous treatments of pathologic vertebral fractures. ⋯ In a Medicare population with bony malignancy and vertebral fractures, percutaneous therapy predicted significantly reduced cost and length of stay versus surgery. Patients who underwent percutaneous therapy were significantly less likely to die, be transferred, or be discharged to rehabilitation facilities, and were more likely to be discharged to home or hospice.
