Material and Geometric Innovations in Lumbar and Cervical Interbody Devices: A Systematic Scoping Review.
Review in Annals of biomedical engineering, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Contemporary interbody spacer designs for spinal fusion surgeries have progressed due to significant mechanical and biological constraints. This scoping review aims to identify and assess current advancements in lumbar and cervical interbody spacer designs, with a focus on geometric configurations and material compositions that minimize subsidence and stress shielding. In accordance with PRISMA-ScR principles, a comprehensive examination of scientific literature and issued patents was performed. The results indicated that the latest advancements emphasize biomechanical optimization via topological design, porosity regulation, and biomimetic architectures. Among the assessed materials, 3D-printed porous titanium and PEEK-coated Ti were identified as promising alternatives, providing a balance of mechanical stability and osseointegration. Additionally, innovative geometries, including gyroid and helicoidal structures were reported to improve stress distribution and facilitate bone ingrowth, thereby reducing implant failure. The evidence suggests a clear trend toward the development of implants that replicate the mechanical and morphological characteristics of cortical bone.
