Outcomes of dual mobility arthroplasty in thumb basal joint arthritis: a clinical and radiographic study of one hundred and fifty prostheses with four-years follow-up.
Observational study in International orthopaedics, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 papers, 1 of them a synthesis that pooled it.
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
This study evaluated the outcomes of double mobility trapeziometacarpal prostheses for treating osteoarthritis (OA) of the trapeziometacarpal (TMC) joint. A prospective observational analysis was conducted on 150 implants with a maximum follow-up of four years, including a clinical and radiographic assessment and an evaluation of complications. The results indicate a prosthesis survival rate of 97.9% after the first two years post-surgery, calculated using the Kaplan-Meier method. Significant improvements were observed in pain reduction (mean VAS at 3 months post-surgery 2,9 and 1.5 after 6 months), hand grip strength (25.93 kg at 6 months post-surgery), and range of motion (Kapandji score from 8.8 to 9.2, comparing the preoperative mean with the mean after the first postoperative month). The complication rate was low, with only two cases of cup migration and one case of trapezium resorption. Patient satisfaction was high due to the rapid functional recovery and reduced invasiveness compared to traditional techniques. Double-mobility prostheses offer a highly effective treatment for stage II and III TMC OA according to the Eaton-Littler classification, with minimal need for revision surgeries.
