Uncertainty pervades low back pain (LBP). This study aimed to explore individuals' experiences of navigating uncertainty when seeking care for their LBP, with a view to better understanding the contexts in which they experience uncertainty and gaining insight into how uncertainty may be better navigated during clinical encounters. We conducted 15 semistructured interviews with people who have experienced LBP. ⋯ Suggestions included making time to (actively) listen to, and acknowledge, patients' concerns; asking open-ended questions; being honest about uncertainty; creating management plans and returning to them; challenging assumptions; remaining curious about patients' context; and providing guidance on how to manage LBP rather than simply giving certainty that symptoms will worsen, lessen, or continue. These findings indicate that many of the uncertainties individuals with LBP experience are intertwined with relational aspects of their interactions with clinicians. Clinicians therefore may need to consider these broader and relational aspects of care when navigating uncertainty with people who experience LBP, bringing attention to the importance of drawing from knowledge produced outside of the usual hierarchy of evidence (eg, systematic reviews and randomised controlled trials).

Randomized Controlled Trial
Mechanisms of education and graded sensorimotor retraining in people with chronic low back pain: a mediation analysis.
An improved understanding of the biopsychosocial influences that contribute to and maintain pain has promoted the development of new efficacious treatments for chronic low back pain (CLBP). This study aimed to investigate the mechanisms of a new treatment-education and graded sensorimotor retraining-on pain and disability. We conducted a preplanned causal mediation analysis of a randomized clinical trial which allocated 276 participants with CLBP to 12 weekly clinical sessions of education and graded sensorimotor retraining (n = 138) or a sham and attention control (n = 138). ⋯ Five of 7 mechanisms (71%) mediated the intervention effect on disability; the largest mediated effects were for beliefs about back pain consequences (-1.66 [-2.62 to -0.87]), pain catastrophizing (-1.06 [-1.79 to -0.53]), and pain self-efficacy (-0.84 [-1.89 to -0.45]). When all 7 mechanisms were considered simultaneously, the joint mediation effect explained most of the intervention effect for both pain and disability. Optimizing interventions to target beliefs about the consequences of back pain, pain catastrophizing, and pain self-efficacy is likely to lead to improved outcomes for people with CLBP.

Observational Study
Predictive value of texture analysis on lumbar MRI in patients with chronic low back pain.
The aim of this study was to determine whether MRI texture analysis could predict the prognosis of patients with non-specific chronic low back pain. ⋯ The texture analysis of lumbar MRI could help identify patients who are more likely to improve their non-specific chronic low back pain through rehabilitation programs, allowing a personalized therapeutic plan to be established.

Da Vinci meets Globus Excelsius GPS: A Totally Robotic Minimally Invasive Anterior and Posterior Lumbar Fusion.
Minimally invasive approaches to the spine via anterior and posterior approaches have been increasing in popularity, culminating in the development of robot-assisted spinal fusions. The da Vinci surgical robot has been used for anterior lumbar interbody fusion (ALIF), with promising results. Similarly, multiple spinal robots have been developed to assist placement of posterior pedicle screws. However, no previous cases have reported on using robots for both anterior and posterior fixation in a single surgery. We present a technical note on the first reported case of a totally robotic minimally invasive anterior and posterior lumbar fusion and instrumentation. ⋯ All-robotic placement of both ALIF and posterior lumbar pedicle fixation may be safe, feasible, and efficacious.

The purpose of the study was to investigate several potential imaging biomarkers of CLBP that may be useful for diagnosis and treatment efficacy evaluation. Proton magnetic resonance spectroscopy (1H-MRS) was used to detect the content and ratio of creatine (Cr), choline (Cho), and lipid (Lip) in the multifidus muscle (Mm) in patients with CLBP and to test for relationships between these metabolites and pain severity and duration. ⋯ Using 1H-MRS, we demonstrated higher Lip and Lip/Cr ratios in the Mm of patients with CLBP, compared to asymptomatic controls. Mm Lip was correlated with CLBP intensity. An increase in Lip in the Mm may be a characteristic finding in CLBP and may offer a useful prognostic marker for guiding rehabilitation strategies.
