OBJECTIVE: We aimed to evaluate the effectiveness of ultrasound-guided facia iliaca compartment (FIC) and erector spinae plane (ESP) blocks in managing postoperative pain following total hip arthroplasty surgery. METHODS: A total of 60 patients were randomized into two groups (n = 30): FIC and ESP blocks were performed with 30 mL 0.25% bupivacaine at the end of the surgery. The patients received intravenous tramadol and patient-controlled postoperative analgesia...

BACKGROUND: Chronic pain in the context of certain factors may be associated with potential for nonmedical prescription opioid use; however, identifying this risk can be challenging and complex. Several variables alone have been associated with non-prescribed opioid use, including depression, anxiety, pain interference, and trauma exposure. Prior research has often failed to integrate these assessments together, which is important as these factors may cluster together in important and complex ways...

INTRODUCTION: Interspinous process devices (IPDs) were developed as minimally invasive alternatives to open decompression surgery for spinal stenosis. However, given high treatment failure and reoperation rates, there has been minimal adoption by the spine surgeons. This study leveraged a national claims database to characterize national IPD usage patterns and postoperative outcomes following IPD implantation. METHOD: Using the PearlDiver database, we identified all patients who underwent 1- or 2-level IPD implantation between 2010 and 2018...

INTRODUCTION: Complex Regional Pain Syndrome (CRPS) most frequently affects the upper limb, with high associated disability. Delays to diagnosis and appropriate treatment can adversely impact prognosis and quality of life, but little is known about the healthcare experiences of people with CRPS. This study aimed to explore lived experiences of diagnosis and treatment for people with upper limb CRPS. METHODS: Participants were recruited through online support groups and multiple public and private healthcare settings in the Greater Wellington Region, New Zealand...

BACKGROUND: In response to the opioid crisis, U.S. states have passed laws requiring urine drug testing (UDT) when opioid analgesics are prescribed for chronic pain. We sought to identify state law UDT requirements. METHODS: We searched NexisUni legal database using terms related to UDT, chronic pain, and opioids. We included laws effective during spring 2022 that required UDT when opioids were prescribed for chronic pain. We performed deductive content analysis, coding laws for mandated UDT frequency, type of clinician and type of payer to whom the law applied, and circumstances under which UDT was mandated...

OBJECTIVE: Chronic low back pain (CLBP) is multifactorial in nature, with recent research highlighting the role of multifidus dysfunction in a subset of nonspecific CLBP. This review aimed to provide a foundational reference that elucidates the pathophysiological cascade of multifidus dysfunction, how it contrasts with other CLBP etiologies and the role of restorative neurostimulation. METHODS: A scoping review of the literature. RESULTS: In total, 194 articles were included, and findings were presented to highlight emerging principles related to multifidus dysfunction and restorative neurostimulation...

BACKGROUND: Genicular nerve radiofrequency ablation (GNRFA) is an effective treatment for chronic knee pain. However, there has been minimal investigation of real-world, long-term outcomes and factors that predict treatment success after GNRFA. OBJECTIVES: To evaluate the effectiveness of GNRFA for chronic knee pain in a real-world population and identify predictive factors. METHODS: Consecutive patients who underwent GNRFA at a tertiary academic center were identified...

BACKGROUND: The aim of this study was to a) evaluate the time between onset of occipital neuralgia symptoms and nerve decompression surgery, b) perform a cost comparison analysis between surgical and non-surgical treatment of occipital neuralgia and c) report postoperative results of nerve decompression for occipital neuralgia. METHODS: 1,112 subjects who underwent screening for nerve decompression surgery were evaluated for occipital neuralgia. 367 (33%) patients met the inclusion criteria...

BACKGROUND: Osteoarthrosis of the lateral atlanto-axial joint (LAAJ) may be a cause of upper neck pain and headache. Intra-articular injection of steroids may provide only short-lasting relief. For intractable pain, arthrodesis of the joint might be considered. OBJECTIVE: To determine the success rates of arthrodesis of the lateral atlanto-axial joint for relieving neck pain and disability. DESIGN: Practice audit. SETTING: Private practice of senior author...

OBJECTIVE: The purpose of this study was to apply network analysis methodology to better understand the relationships between pain-related measures among people with chronic pain. METHODS: We analyzed data from a cross-sectional sample of 4,614 active duty service members with chronic pain referred to one military interdisciplinary pain management center between 2014 and 2021. Using a combination of Patient-Reported Outcomes Measurement Information System measures and other pain-related measures, we applied the 'EBICglasso' algorithm to create regularized partial correlation networks that would identify the most influential measures...
