BACKGROUND: Over the past 2 decades, the increase in the utilization of interventional techniques has been a cause for concern. Despite multiple regulations to reduce utilization of interventional techniques, growth patterns continued through 2009. A declining trend was observed in a previous evaluation; however, a comparative analysis of utilization patterns of interventional techniques has not been performed showing utilization before and after the enactment of the Affordable Care Act (ACA)...

Interbody fusion with posterior instrumentation is a common method for treating lumbar degenerative disc diseases. However, the high rigidity of the fusion construct may produce abnormal stresses at the adjacent segment and lead to adjacent segment degeneration (ASD). As such, biodegradable implants are becoming more popular for use in orthopaedic surgery. These implants offer sufficient stability for fusion but at a reduced stiffness. Tailored to degrade over a specific timeframe, biodegradable implants could potentially mitigate the drawbacks of conventional stiff constructs and reduce the loading on adjacent segments...

BACKGROUND: Low bone mass in adolescent idiopathic scoliosis patients has been well reported. Poor bone quality was regarded as a new and unique prognostic factor in aggravating the curve progression. However, the potential biomechanical correlation between them remains unclear. METHODS: Three-dimensional finite element models of idiopathic scoliotic spine with different bone mineral status were created for axial loading simulation. Axial load of three different body weights were applied on different bone mineral mass models...

Percutaneous image-guided rupture of lumbar facet synovial cysts can improve clinical outcomes and obviate the need for open surgery. This series describes eleven patients who had successful CT-guided lumbar facet synovial cyst ruptures, 82% of which experienced excellent pain relief at a minimum of one-year follow-up. Of the five patients who failed prior fluoroscopic-guided synovial cyst rupture, 80% had a successful CT-guided rupture and one-year sustained pain relief. These findings reinforce minimally invasive CT-guided treatment as an excellent option to improve patient symptoms and potentially avoid open surgery...

Radiofrequency facet ablation (RFA) has been performed using the same technique for over 50 years. Except for variations in electrode size, tip shape, and change in radiofrequency (RF) stimulation parameters, using standard, pulsed, and cooled RF wavelengths, the target points have remained absolutely unchanged from the original work describing RFA for lumbar pain control. Degenerative changes in the facet joint and capsule are the primary location for the majority of lumbar segmental pathology and pain. Multiple studies show that the degenerated facet joint is richly innervated as a result of the inflammatory overgrowth of the synovium...

Background: In the lumbar spine, degenerative spondylolisthesis or degenerative (not traumatic) slippage of one vertebral body over another is divided into 4 grades - grade I (25%), grade II (50%), grade III (75%), and grade IV (100%). Dynamic X-rays, magnetic resonance (MR), and computed tomography (CT) scans document the slip secondary to arthritic changes of the facet joint plus stenosis, ossification of the yellow ligament, disc herniations, and synovial cysts. MR best demonstrates soft tissue pathology whereas CT better delineates ossific/calcified disease...

Patient satisfaction assessments, such as the Press Ganey surveys, have been adopted by the Centers for Medicare & Medicaid Services to help determine reimbursements. It is uncertain what facets most affect survey scores among patients who have received total joint arthroplasty (TJA). This study explored which factors guide scores for TJA patients. Specifically, the authors assessed (1) which Press Ganey survey features affected the patients' overall hospital rating and (2) whether survey scores were disparate between patients who did and patient who did not have complications...

BACKGROUND: Osteoarthritis research has been most commonly performed in the setting of the articular cartilage of the knee. To the best of our knowledge, no studies have evaluated the role of adiponectin in osteoarthritis of the lumbar facet joint (FJOA). Therefore, in this study, we explored whether adiponectin was expressed in the lumbar facet joints and evaluated the role of adiponectin in FJOA. METHODS: We enrolled patients who underwent lumbar computed tomography (CT) and magnetic resonance imaging (MRI) at the Orthopedic Department of the First Affiliated Hospital of Nanchang from May 2015 to June 2016...
