Treatment of Femoral Head Osteonecrosis with Ozone Therapy: Pilot Trial of a New Therapeutic Approach.

Background: Osteonecrosis of the femoral head (ONFH) is a progressive and painful disorder due to impaired blood supply to the femoral head, yet little is known about the effect of ozone therapy in femoral head necrosis.

Objectives: We aimed to evaluate the clinical and radiographic outcomes of ozone therapy in the treatment of ONFH.

Study Design: Nonrandomized clinical trial.

Long-Term Outcomes of Epidurals with Lidocaine With or Without Steroids for Lumbar Disc Herniation and Spinal Stenosis: A Meta-Analysis.

Background: Previous meta-analyses examined only the short-term differences between lidocaine and steroids vs lidocaine alone in treating lumbar degenerative diseases. Long-term outcomes (1-2 years) in patients with lumbar disc herniation (LDH) and lumbar central spinal stenosis (LCSS) have not yet been systematically evaluated.

Objective: The objective of our study was to assess quantitatively the difference in efficacy at 1 to 2 years between lidocaine alone vs lidocaine and steroids for the management of LDH or LCSS.

The effect of ultrasound-guided percutaneous ozone injection around cervical dorsal root ganglion in zoster-associated pain: a retrospective study.

Objective: This study was to evaluate the effectiveness of ultrasound-guided percutaneous ozone injections around the cervical dorsal root ganglions of zoster-associated pain (ZAP) patients.

Study Design: Retrospective comparative study.

Settings: The study was conducted at a pain center of a university hospital.

Changes in neurotrophic and inflammatory factors in the cerebrospinal fluid of patients with postherpetic neuralgia.

Inflammatory and neurotrophic factors are involved in postherpetic neuralgia (PHN), but the association of these factors in the cerebrospinal fluid (CSF) with the level of pain is poorly known. The present study aimed to examine the changes in neurotrophic and inflammatory factors in the CSF of patients with PHN and to study the correlation between these factors and the degree of pain. Fifty patients with PHN and 28 patients with hemifacial spasm (as controls) were recruited between May 2015 and March 2016.
