Purpose Of Review: To summarize the history of titanium implants in spine fusion surgery and its evolution over time.
Recent Findings: Titanium interbody cages used in spine fusion surgery have evolved from solid metal blocks to porous structures with varying shapes and sizes in order to provide stability while minimizing adverse side effects. Advancements in technology, especially 3D printing, have allowed for the creation of highly customizable spinal implants to fit patient specific needs. Recent evidence suggests that customizing shape and density of the implants may improve patient outcomes compared to current industry standards. Future work is warranted to determine the practical feasibility and long-term clinical outcomes of patients using 3D printed spine fusion implants. Outcomes in spine fusion surgery have improved greatly due to technological advancements. 3D printed spinal implants, in particular, may improve outcomes in patients undergoing spine fusion surgery when compared to current industry standards. Long term follow up and direct comparison between implant characteristics is required for the adoption of 3D printed implants as the standard of care.

Study Design: This is a retrospective single-center study.
Purpose: The purpose is to investigate the incidence of distal junctional kyphosis (DJK) when fused proximal to the stable sagittal vertebra (SSV) in adolescent idiopathic scoliosis (AIS) patients undergoing selective thoracic fusion.
Methods: We retrospectively reviewed a consecutive cohort of surgically treated AIS patients with Lenke 1-2 A/B curves between 2011 and 2022 with a minimum of 2 years of follow-up.

Purpose: To investigate the images and treatment differences for Type IIIa atlantoaxial rotary dislocation (AARD) by comparing the imaging characteristics of patients with Type III and Type IIIa AARD.
Methods: The present study retrospectively analyzed a cohort of 35 patients who underwent posterior C1-C2 intra-articular fusion due to AARD from our hospital database. Among them, 23 patients were diagnosed with Type III AARD, while the remaining 12 patients were diagnosed with Type IIIa AARD.

Background Sacroiliac joint fusion is performed to stabilize and fuse the joint in patients with degenerative sacroiliitis and joint dysfunction. While several posterior techniques and implants exist as alternatives to lateral approaches, biomechanical and clinical performance data for these systems used as standalone remains limited. This article provides a preliminary cadaveric and clinical assessment of a novel posterior intra-articular sacroiliac fusion implant system.

For lumbar spinal canal stenosis, endoscopic spine surgery typically employs a unilateral approach. While this approach has the advantage of early access to the lamina, it risks damage to the facet joint on the entry side. Additionally, decompression of the ipsilateral lateral recess can be challenging, sometimes resulting in inadequate decompression laterally, leading to incomplete symptom relief.
