Because of its ability to superimpose imaging data on a patient, while anchoring the user's view to the immediate surroundings, augmented reality (AR) has the potential to dramatically improve the accuracy and reduce the time required for preoperative planning and performance of minimally invasive spine surgeries and procedures. Described and reported herein is the direct clinical application of AR navigation on a series of common percutaneous image-guided spine procedures. ⋯ This data set suggests that AR navigation, utilizing a VN, is an emerging, accurate, valuable additive method for surgical and procedural planning for percutaneous image-guided spinal procedures and has potential to be applied to a broad range of clinical and surgical applications.

Randomized Controlled Trial Multicenter Study
Long-term outcomes following intraosseous basivertebral nerve ablation for the treatment of chronic low back pain: 5-year treatment arm results from a prospective randomized double-blind sham-controlled multi-center study.
Damaged or degenerated vertebral endplates are a significant cause of vertebrogenic chronic low back pain (CLBP). Modic changes are one objective MRI biomarker for these patients. Prior data from the treatment arm of a sham-controlled, RCT showed maintenance of clinical improvements at 2 years following ablation of the basivertebral nerve (BVN). This study reports 5-year clinical outcomes. ⋯ CLBP patients treated with BVN ablation exhibit sustained clinical improvements in function and pain with high responder rates at a mean of 6.4 years following treatment. BVN ablation is a durable, minimally invasive treatment for vertebrogenic CLBP.

Individuals with low back pain (LBP) often turn to complementary and alternative medicine (CAM) to seek relief. The purpose of this study was to determine mention of CAM in LBP clinical practice guidelines and assess the quality of CAM recommendations using the Appraisal of Guidelines, Research and Evaluation II (AGREE II) instrument. ⋯ The majority of LBP guidelines made CAM recommendations. The quality of CAM recommendations is significantly lower than overall recommendations across all domains with the exception of scope and purpose and editorial independence. This difference highlights the need for CAM recommendation quality improvement. Future research should identify CAM therapies which are supported by sufficient evidence to serve as the basis for guideline development.

Multicenter Study
Development and validation of a prediction tool for pain reduction in adult patients undergoing elective lumbar spinal fusion: a multicentre cohort study.
On average, 56% of patients report a clinically relevant reduction in pain after lumbar spinal fusion (LSF). Preoperatively identifying which patient will benefit from LSF is paramount to improve clinical decision making, expectation management and treatment selection. Therefore, this multicentre study aimed to develop and validate a clinical prediction tool for a clinically relevant reduction in pain 1 to 2 years after elective LSF. ⋯ Using the developed nomogram surgeons can estimate the probability of achieving a clinically relevant pain reduction 1 to 2 years after LSF and consequently inform patients on expected outcomes when considering treatment.

Observational Study
Back pain "red flags": which are most predictive of serious pathology in the Emergency Department?
To determine the frequency of red flag signs and symptoms in patients presenting with back pain to the Emergency Department (ED) and association with serious pathologies and investigations performed. ⋯ The majority of this study cohort had back pain of benign cause. Some red flags were associated with greater risk of serious pathology, others were not. Further evidence regarding red flags and their association with serious pathology is required, to better inform clinical guidelines.
