Review Meta Analysis
The efficacy of primary sacroiliac joint fusion for low back pain caused by sacroiliac joint pathology: a systematic review and meta-analysis.
Conduct a systematic review to quantify the effect of primary sacroiliac joint fusion (SIJF) for the treatment of sacroiliac (SI) joint pathology on patient reported outcomes. ⋯ CRD42020206149 (25th September 2020).

Review Meta Analysis
The impact of traumatic herniated discs in cervical facets dislocations treatments: systematic review and meta-analysis.
Traumatic facet dislocations in the subaxial cervical spine, also known as locked facets, are commonly associated with neurological deficits. The fear of the presence of an associated traumatic disc herniation and consequent neurological worsening usually causes a delay in the spinal realignment. This study's aim is an analysis of safety and efficacy when treating acute cervical traumatic facet dislocations using cranial-cervical traction or posterior open reduction and fixation in the presence of disc herniations. ⋯ Traumatic disc herniation in cervical facet dislocations is not an absolute contraindication of cranial-cervical traction or posterior open reduction. Early realignment of the spine could bring more neurological benefits than waiting for an MRI or surgical discectomy. However, caution is needed in this review's data interpretation until prospective and well-designed studies are performed.

Review Meta Analysis
Lumbar plexus safe working zones with lateral lumbar interbody fusion: a systematic review and meta-analysis.
Significant risk of injury to the lumbar plexus and its departing motor and sensory nerves exists with lateral lumbar interbody fusion (LLIF). Several cadaveric and imaging studies have investigated the lumbar plexus position with respect to the vertebral body anteroposterior plane. To date, no systematic review and meta-analysis of the lumbar plexus safe working zones for LLIF has been performed. ⋯ This is the first comprehensive systematic review and meta-analysis of the lumbar neural components and safe working zones for LLIF. Our analysis suggests that the lumbar plexus is significantly displaced ventrally with the supine compared to lateral decubitus position, and that MRI may overestimate ventral encroachment of lumbar plexus.

To determine whether the open or the minimally invasive transforaminal lumbar interbody fusion (O-TLIF, MI-TLIF) is the favored treatment, we provide first meta-analyses using prospective studies with at least two years follow-up only and present the clinical relevance of statistical results for the first time. ⋯ After at least two years, O-TLIF and MI-TLIF can be considered equally efficacious, which simplifies surgeons' decision between both treatments, however, with the safety outcome measure postoperative complications per case and the perioperative outcome measures EBL and LOS in favor of MI-TLIF. LEVEL OF EVIDENCE I: Well conducted meta-analyses, systematic reviews, or RCTs with a low risk of bias.

Interbody fusion is commonly utilized for arthrodesis and stability among patients undergoing spine surgery. Over the last few decades, interbody device materials, such as titanium and polyetheretherketone (PEEK), have been replacing traditional autografts and allografts for interbody fusion. As such, with the exponential growth of bioengineering, a large variety cage surface technologies exist. Different combinations of cage component materials and surface modifications have been created to optimize interbody constructs for surgical use. This review aims to provide a comprehensive overview of common surface technologies, their performance in the clinical setting, and recent modifications and material combinations. ⋯ Interbody devices have rapidly evolved over the last few decades. Biomaterial and biomechanical modifications have allowed for continued design optimization. While titanium has a high osseointegrative capacity, it also has a high elastic modulus and is radio-opaque. PEEK, on the other hand, has a lower elastic modulus and is radiolucent, though PEEK has poor osseointegrative capacity. Surface modifications, material development advancements, and hybrid material devices have been utilized in search of an optimal spinal implant which maximizes the advantages and minimizes the disadvantages of each interbody material.
