The Effect of Medial Branch Block on Postoperative Residual Pain Relieve After Percutaneous Kyphoplasty: A Randomized Controlled Trial With 12-Month Follow-up.
Percutaneous kyphoplasty (PKP) is a minimally invasive technique, and effective treatment, for an osteoporotic vertebral compression fracture (OVCF). Residual back pain is the most common complication of PKP. Medial branch block (MBB) is a treatment option for painful OVCF, it can break the vicious cycle to release short- or long-term pain. ⋯ MBB can effectively relieve back pain and reduce the incidence of residual back pain in OVCF patients after PKP surgery. Besides, it can also significantly improve postoperative physical function and patients' satisfaction with treatment.

The Effect of Normal Saline Injection Volumes on the Optic Nerve Sheath Diameter during Thoracic Epidural Analgesia.
Saline or local anesthetic injection into the epidural space increases intracranial pressure (ICP), at least transiently. Measurement of the optic nerve sheath diameter (ONSD) using ocular ultrasonography is one of the noninvasive methods for ICP assessment. ⋯ Twenty milliliters of normal saline epidural injection resulted in a significant increase of ONSD, as compared to the 5 mL and 10 mL groups. Our results also indicate that an increase of ONSD occurs in accordance with the injected volume of normal saline.

Three Needles Approach-A New Technique of Genicular Nerves Radiofrequency Ablation for Pain Relief in Advanced Chronic Knee Osteoarthritis: A Randomized Trial.
Ablation of the genicular nerves (GN) has emerged as a useful alternative therapeutic modality in chronic knee osteoarthritis (OA) specially for high-risk patients. However, in some cases due to the presence of other articular branches or anatomical variability, it may have a poor impact in relieving pain. Ablation of other or additional articular branches might have different outcomes. ⋯ Compared to the conventional single-needle GN ablation technique, the 3-needle approach appears to be a promising, safe, and more effective ablation technique for patients with chronic knee OA.

Vitamin D deficiency has been linked to nonspecific low back pain (Ns-LBP); however, the role of inflammation as a possible mediator between vitamin D levels and Ns-LBP is not well understood. ⋯ Patients with Ns-LBP had lower vitamin D and higher inflammatory marker levels. This association between hypovitaminosis D and Ns-CLBP may be mediated by IL-6. Therefore, large-scale clinical trials are warranted to investigate the clinical efficacy of vitamin D supplementation for decreasing inflammation and relieving Ns-LBP.

Comparison of Intravascular Injection Incidences and Technical Easiness Between Anteroposterior and Oblique Approaches During S1 Transforaminal Epidural Injection.
Transforaminal epidural injection (TFEI) is a useful intervention for radicular leg pain. Compared to TFEI in lumbar level, S1 TFEI is reported to have higher incidence rates of intravascular injection as well as technical difficulties. ⋯ Our study demonstrated reduced incidence rates of intravascular injection and reduced foramen passage time and radiation dosage with the use of OB view method during S1 TFEI.
