Randomized Controlled Trial
The Potential Impact of Venobasillar System Morphology and Applied Technique on Epidural Cement Leakage with Percutaneous Vertebroplasty.
Bone cement leakage during vertebroplasty is a frequently reported complication with the potential for neural injury. ⋯ The type of venobasillar system should be taken into account when planning a vertebroplasty procedure as a magistral type of venobasillar system is associated with the increased rate of epidural cement leakage. It is important to try and achieve a large distance between the needle tip and the midline, especially when a magistral type of venobasillar system is present, to reduce the risk of epidural cement leakage.

Randomized Controlled Trial
A New Look on Adding Dexamethasone as an Adjuvant to Caudal Bupivacaine; Efficacy on Postoperative Pain and Vomiting in Pediatric Patients.
Controlling postoperative pain and vomiting in children remains a great challenge. ⋯ Analgesic and antiemetic effects of dexamethasone as an adjunct to caudal block with bupivacaine (0.25%) 0.5 mL/kg is similar whether administered intravenously 0.5 mg/kg or caudally 0.1 mg/kg.

It is well documented that epidural adhesion is associated with spinal pain. However, the underlying mechanism of spinal pain generation by epidural adhesion has not yet been elucidated. ⋯ The current study clearly demonstrated that epidural adhesion causes significantly increased stress in the spinal nerves, especially at the DRG. We believe that the increased stress on the spinal nerve might elicit more pain under similar magnitudes of lumbar disc protrusion.

Clinical Trial
Stimulation of the Spinal Cord and Dorsal Nerve Roots for Chronic Groin, Pelvic, and Abdominal Pain.
Chronic neuropathic groin pain is a common problem. It can arise following surgery or trauma, or spontaneously as part of various pelvic pain syndromes. A number of different stimulation techniques have been reported in the literature to treat this area, but due to the complex anatomy of the region, it can be difficult to target effectively with paresthesias. ⋯ Dorsal nerve root stimulation is an effective long-term treatment for neuropathic groin pain.

Painful vertebral compression fractures (VCF) caused by osteoporosis are a common health problem in the elderly population. If conservative treatments are unsuccessful, surgical treatments like vertebroplasty or kyphoplasty are recommended. But the use of Polymethylmethacrylat (PMMA) bone cement for augmentation surgery is associated with risks. ⋯ The study results demonstrate that the clinical outcome of VAS and ODI of using the silicon polymer VK100 is comparable or slightly better than using PMMA. VK 100 shows a trend to minor additional fractures during the follow-up. However, height restoration is not satisfactory in comparison to PMMA, although vertebral height stayed more or less constant in the VK group. To address the augmentation success further, it would be necessary to study a larger patient group over a longer study period and to assess additional parameters such as bone density and injected amount of filling material.
