To evaluate change in fear of movement and the relationship of fear of movement and pain intensity to low back disability and general health-related quality of life over a 2-year period. ⋯ We found that greater levels of fear of movement were related to greater levels of low back disability, following lumbar spine surgery, in a longitudinal study. This shows the need to address fear of movement in prehabilitation/rehabilitation pre- or postsurgically to improve health outcomes for patients who undergo lumbar spine surgery.

Postoperative CSF Leak After Lumbar Total Disc Replacement (TDR): A Diagnostic and Management Challenge.
Lumbar total disc replacement is increasingly becoming a more common treatment for discogenic low back pain refractory to conservative measures. Nevertheless, several complications have been reported, including, among others, wound infection, vascular injury, retrograde ejaculation, postsympathectomy syndrome, ileus, and cerebrospinal fluid (CSF) leak. Although CSF leakage is rare, we discuss a case of CSF leakage and the diagnosis and management of CSF leakage after lumbar total disc replacement. ⋯ Our patient ultimately required device removal, direct repair, and replacement with a different prosthesis to treat his CSF leak.

Chronic inflammation increases the production of cytokines and activates proinflammatory pathways which may lead to nonspecific low back pain (LBP). We systematically reviewed the literature to investigate whether inflammatory biomarkers are associated with nonspecific LBP. ⋯ Our findings support the notion of a positive association between inflammatory biomarkers and nonspecific LBP, specifically for CRP, TNFs, and IL-6. Although further high quality longitudinal studies are needed to confirm these findings and evaluate the magnitude of these associations, our findings suggest a role of inflammation in the pathogenesis of nonspecific LBP.

The Illness Invalidation Inventory (3*I) was designed to assess individuals' perceived invalidation regarding chronic pain experiences. However, no study has yet investigated the psychometric properties of the 3*I among individuals with chronic low back pain (CLBP). Given the personal and societal impact of CLBP and the potential for invalidation associated with this condition, the current study sought to examine the psychometric properties of the 3*I among individuals with CLBP. ⋯ The 2-factor model of the 3*I "family members" subscale identified in the current study reflects previous findings and extends the psychometric validity of the 3*I to a US multiethnic sample of individuals with CLBP.
