Over the last years, the number of vertebral arthrodesis has been steadily increasing. The use of iliac crest bone autograft remains the "gold standard" for bone graft substitute in these procedures. However, this solution has some side effects, such as the problem of donor site morbidity indicating that there is a real need for adequate alternatives. This pilot study aimed to evaluate the usefulness of chitosan (Ch) porous 3D scaffolds incorporated with resolvin D1 (RvD1) as an alternative implant to iliac bone autograft. ⋯ These results demonstrate the potential of these scaffolds for bone tissue repair applications.

Review Meta Analysis
Comparison of clinical outcomes associated with spinal cord stimulation (SCS) or conventional medical management (CMM) for chronic pain: a systematic review and meta-analysis.
This study aims to evaluate the efficacy and safety of spinal cord stimulation (SCS) compared to conventional medical management (CMM) for patients diagnosed with chronic pain. Furthermore, the study seeks to compare the utilization of analgesics, as well as the long-term outcomes in terms of quality of life and functional capacity. ⋯ SCS is an effective treatment to relieve the pain level of chronic pain, decrease analgesic usage, and increase long-term quality of life and functional capacity.

Review Meta Analysis
Application of rhBMP in spinal fusion surgery: any correlation of cancer incidence? A systematic review and meta-analysis.
Safety concerns regarding the application of bone morphogenetic proteins (BMPs) have been highlighted in recent years. It is noted that both BMP and their receptors being identified as a trigger for cancer growth. Here, we aimed to determine the safety and efficacy of BMP for spinal fusion surgery. ⋯ Our study found that rhBMP was not associated with the increased risk of cancer incidence within the rhBMP cohort. Still, we did face several limitations, in which further studies are needed to confirm the result of our meta-analysis.

The purpose of this study was to evaluate the efficacy of sinuvertebral nerve blocks in the diagnosis of discogenic low back pain. ⋯ The effect of sinuvertebral nerve block as a diagnostic tool for discogenic low back pain is similar to that of discoblock, and it is a promising tool that deserves further study.

Review
Patient and surgical predictors of 3D correction in posterior spinal fusion: a systematic review.
Restoration of three-dimensional (3D) alignment is critical in correcting patients with adolescent idiopathic scoliosis using posterior spinal fusion (PSF). However, current studies mostly rely on 2D radiographs, resulting in inaccurate assessment of surgical correction and underlying predictive factors. While 3D reconstruction of biplanar radiographs is a reliable and accurate tool for quantifying spinal deformity, no study has reviewed the current literature on its use in evaluating surgical prognosis. ⋯ Rod contouring and UIV/LIV selection should be based on preoperative 3D TK in order to achieve normal postoperative alignment. Specifically, Lenke 1 patients with high-lying rotations should be fused distally at NV-1, while hypokyphotic patients with large lumbar curves and truncal shift should be fused at NV to improve lumbar alignment. Lenke 1C curves should be corrected using > 50% LIV rotation counterclockwise to the lumbar rotation. Further investigation should compare surgical correction between pedicle-screw and hybrid constructs using matched cohorts. DJK and overbending rods are potential predictors of postoperative alignment.
