In response to increasing use of lumbar fusion for improving back pain, despite unclear efficacy, particularly among injured workers, some insurers have developed limited coverage policies. Washington State's workers' compensation (WC) program requires imaging confirmation of instability and limits initial fusions to a single level. In contrast, California requires coverage if a second opinion supports surgery, allows initial multilevel fusion, and provides additional reimbursement for surgical implants. There are no studies that compare population-level effects of these policy differences on utilization, costs, and safety of lumbar fusion. ⋯ Broader lumbar fusion coverage policy was associated with greater use of lumbar fusion, use of more invasive operations, more reoperations, higher rates of complications, and greater inpatient costs.

Traditional anterior spinal surgery (TASS) for the thoracolumbar spine is associated with significant morbidities. To avoid excessive tissue damage, minimal access spinal surgery (MASS) has been developed to treat a variety of anterior spinal disorders at the authors' institution. No previous reports comparing the outcomes of MASS and TASS for the treatment of infectious spondylitis were noted in the literature, to our knowledge. ⋯ Minimal access spinal surgery has been suggested to be an effective and safe technique in treating thoracic and lumbar infectious spondylitis. Minimal access spinal surgery did not need endoscopic equipments or complex surgical instruments. Furthermore, in comparison to TASS, MASS resulted in a reduced blood transfusion amount, decreased intensive care unit stay, reduced overall length of stay, and reduced surgical complication rate. Nevertheless, the risks may be increased in performing MASS on patients with multilevel involvement, which could be associated with high vascularity, alternated vascular anatomy, increased soft-tissue edema, and adhesion.

Although giant cell tumors (GCTs) are histologically benign, they may become locally aggressive bone tumors. As these lesions tend to respond poorly to radio- and chemotherapy, currently the standard surgical paradigm for the treatment of spinal GCTs involves en bloc surgical resection. Denosumab is a newly developed monoclonal antibody designed to inhibit the receptor activator of nuclear factor kappa-B ligand (RANKL) which has already been demonstrated to induce marked radiographic responses on GCTs of the appendicular skeleton. Nevertheless, the role of denosumab in the treatment algorithm of GCTs of the spine has not yet been defined. ⋯ This is the first report of sustained long-term complete clinical and radiographic regression of a GCT of the spine after treatment with the new RANKL antibody denosumab. Although future long-term follow-up studies are still necessary to establish important key points regarding the best therapeutic protocol with such a new drug (such as the optimal time frame to keep the patient under treatment), denosumab promises to bring major changes to the current therapeutic paradigm for GCTs of the spine, which, up to now, has strongly relied on en bloc surgical resection.

Prognosis of minor lumbar curve correction after selective thoracic fusion in idiopathic scoliosis is well defined. However, the prognosis of minor thoracic curve after isolated anterior fusion of the major lumbar curve has not been well described. ⋯ Selective anterior fusion of the major thoracolumbar/lumbar curve was an effective method for the treatment of Lenke Type 5C curves. Minor thoracic curves did not progress after selective fusion of thoracolumbar/lumbar curves in minimum 2-year follow-up.

High prevalence rates of depression have been found in patients with chronic spinal disorder (CSD). The biopsychosocial model has become widely adopted and, with it, the role of psychopathology in the development and/or exacerbation of CSD has become increasingly recognized. Standardized diagnostic criteria, such as the Diagnostic and Statistical Manual of Mental Disorders (DSM), have been used to diagnose major depressive disorder (MDD). Many measures of MDD (and depressive symptom inventories) have been developed during the past 50 years, but their comparative utility in CSD populations is still unclear. ⋯ Compared to the HRSD, both BDI and PHQ-9 are relatively short and easy to self-administer. The cut-off scores established in this study may be used to reliably determine whether a person should be evaluated more thoroughly for an MDD diagnosis. Using an acknowledged "gold standard," the HRSD, BDI and PHQ-9 showed similar validity to recommend their use for future clinical and research purposes. The SF-36 is less appropriate for diagnosing MDD.
