Observational Study
Percutaneous vertebroplasty combined with percutaneous pediculoplasty for lytic vertebral body and pedicle lesions of metastatic tumors.
Percutaneous pediculoplasty (PP) consists of the injection of Poly(methyl methacrylate) (PMMA) into the fractured pedicle or lytic vertebral pedicle lesions, as a technique derived from vertebroplasty. ⋯ PV and PP via the transpedicular approach for infiltrated vertebral bodies and infiltrated pedicles of metastatic tumors may be considered a valid therapeutic option.

Randomized Controlled Trial
Effectiveness of Parasagittal Interlaminar Epidural Local Anesthetic with or without Steroid in Chronic Lumbosacral Pain: A Randomized, Double-Blind Clinical Trial.
Epidural injections (EI) are the most commonly performed minimally invasive intervention to manage chronic low back pain (CLBP) with lumbosacral radicular pain (LRP). Local anesthetic (LA) and/or steroids are frequently used injectates for EI and are reported with variable effectiveness. The majority of earlier studies have used either caudal, transforaminal (TF), or undefined interlaminar approaches for EI. The parasaggital interlaminar (PIL) approach route is reported to have good ventral epidural spread and comparable effectiveness to the TF route. However, there is a lack of head-to-head comparative effectiveness research of LA with or without steroid for managing CLBP with LRP using a PIL approach. ⋯ Using a PIL approach and the addition of steroid to LA for EI may provide superior effectiveness in terms of extent and duration of pain relief for managing CLBP with unilateral LRP, even though, local anesthetic alone also was effective.

Randomized Controlled Trial
Intravenous parecoxib and continuous femoral block for postoperative analgesia after total knee arthroplasty. A randomized, double-blind, prospective trial.
Up until now, the optimal strategy for postoperative pain management after total knee arthroplasty (TKA) remains to be elucidated. ⋯ According to our findings intravenous parecoxib in combination with continuous femoral block provided superior analgesic efficacy and opioid sparing effects in patients undergoing TKA.

Comparative Study
Economic Analysis of Kiva VCF Treatment System Compared to Balloon Kyphoplasty Using Randomized Kiva Safety and Effectiveness Trial (KAST) Data.
Vertebral compression fractures (VCFs) are the most common osteoporotic fractures and cause persistent pain, kyphotic deformity, weight loss, depression, reduced quality of life, and even death. Current surgical approaches for the treatment of VCF include vertebroplasty (VP) and balloon kyphoplasty (BK). The Kiva® VCF Treatment System (Kiva System) is a next-generation alternative surgical intervention in which a percutaneously introduced nitinol Osteo Coil guidewire is advanced through a deployment cannula and subsequently a PEEK Implant is implanted incrementally and fully coiled in the vertebral body. The Kiva System's effectiveness for the treatment of VCF has been evaluated in a large randomized controlled trial, the Kiva Safety and Effectiveness Trial (KAST). The Kiva System was non-inferior to BK with respect to pain reduction (70.8% vs. 71.8% in Visual Analogue Scale) and physical function restoration (38.1 % vs. 42.2% reduction in Oswestry Disability Index) while using less bone cement. The economic impact of the Kiva system has yet to be analyzed. ⋯ This first-ever economic analysis of the KAST data showed that the Kiva System for vertebral augmentation is hospital resource and cost saving over BK in a hospital setting over 2 years. These savings are attributable to reduced risk of developing adjacent-level fractures with the Kiva System compared to BK.

Pain interventionists can interrupt pain through anesthetic blockade of neural transmission to virtually any part of the body. Temporary pain relief can be achieved by the direct application of targeted anesthetic. Diagnostically, nerve blocks help identify specific pain generators, refine differential diagnosis, and disrupt the neural transmission mechanisms to stop pain generation peripherally. ⋯ This study's results support the hypothesis that a combined interventional and cognitive motivational counseling treatment program can be effective in decreasing spine pain, reducing prescription pain medication use, and improving overall quality of life in chronic spine pain patients.
