Femoral Stem Dislocation Caused by Trunnionosis Along with Adverse Local Tissue Reaction: A Case Report and a New Technique of Head to Cone Cementing.
Article in The archives of bone and joint surgery, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
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
In total hip replacement (THR), fretting and corrosion at the modular head-neck junction (trunnionosis) may cause adverse local tissue reaction (ALTR). In this report, we presented a 34 years woman with a history of THR eight years ago, presenting with acute pain and limping. The radiographic assessment revealed stem-head dislocation for which a revision hip surgery was planned. Surprisingly, we observed pseudotumor and tissue necrosis resulting from the body's reaction to cobalt-chromium alloy. The revision surgery entailed pseudotumor debridement and replacing the femoral head with a new metal head (size 36, long). Due to the separation of the femoral head on a stem, we fixed it on a stem using bone cement. The stem (Omnifit®, Stryker®) was well-fixed and retained to avoid fractures and infection risk. This technique revealed an acceptable outcome without recurrence of ALTR after a one-year follow-up. Our findings suggest that stem dislocation secondary to trunnionosis might be a long-term complication after THR with subsequent ALTR.
