The Effects of Lumbar Spinal Fusion on Spinopelvic Biomechanics Years After Primary Total Hip Arthroplasty: A Case Report.
Article in Cureus, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
Spinopelvic biomechanics are critically important for hip stability following total hip arthroplasty (THA). Lumbar spinal fusion, particularly multilevel fusion, alters the dynamic relationship between the spine, pelvis, and hip, resulting in reduced pelvic mobility and increased risk of prosthetic instability. We present the case of an 85-year-old woman with a well-functioning right THA that remained stable for 11 years until she underwent L2-L5 laminectomy and posterior spinal fusion with L4-L5 transforaminal lumbar interbody fusion. Within the subsequent two years, she experienced two distinct episodes of posterior prosthetic hip dislocation, each occurring during forward flexion. This case highlights the biomechanical consequences of lumbar fusion, reviews the underlying mechanisms of altered spinopelvic mobility, and discusses strategies for preventing and addressing hip instability in patients with spinal stiffness or fusion.
