Thumb Reconstruction Using Osseointegrated Dental Implants for Prosthetic Retention Following Gunshot Amputation: 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. 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
Thumb amputations severely compromise hand function, particularly grip and opposition. Osseointegration, originally developed for dental implantation, has become a promising method for directly anchoring prostheses to bone. This technique uses a two-stage protocol: first, a dental implant is placed into the medullary canal and allowed to integrate with the surrounding bone; once stable osseointegration is confirmed, a skin-penetrating abutment and custom prosthesis are attached. This approach provides secure fixation even when bone stock is limited and offers several advantages over conventional prosthetics, including improved retention, stronger grip and pinch function, increased range of motion, and enhanced osseoperceptive feedback. We present the case of a 38-year-old male who sustained a gunshot injury resulting in amputation at the base of the proximal phalanx of the right thumb. The first stage of reconstruction included metacarpophalangeal joint arthrodesis and first web-space widening using a four-flap Z-plasty. A dental implant was placed across the fusion site to provide both fixation for the arthrodesis and a stable anchoring platform for a custom prosthesis. This case suggests that osseointegrated dental implants may provide a feasible retention option for thumb prosthetic reconstruction, particularly when conventional reconstructive strategies are limited or contraindicated.
