Amandys® pyrocarbon interposition wrist arthroplasty: a systematic review of clinical outcomes and complications.
Review in Journal of hand and microsurgery, 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
Background: Pyrocarbon interposition arthroplasty (Amandys®) has been proposed as a motion-preserving salvage procedure for advanced wrist degeneration. However, its clinical outcomes, complication profile, and role within the contemporary wrist salvage algorithm remain incompletely defined. Objective: To systematically review the clinical outcomes, complications, and revision patterns associated with Amandys® pyrocarbon interposition wrist arthroplasty, without performing a direct comparative analysis with other wrist salvage procedures, and to clarify its role among current treatment options. Materials and methods: A systematic review of the literature was conducted using PubMed, Scopus, and Web of Science databases. The search term "Amandys" was used without additional filters. Clinical studies reporting outcomes of Amandys® wrist arthroplasty were included. Data extraction focused on study characteristics, clinical outcomes, complications, and revision procedures. Methodological quality was assessed using the Coleman Methodology Score. Results: Ten clinical studies met the inclusion criteria, comprising a total of 224 wrists treated with Amandys® interposition arthroplasty. Pain reduction and improvement in patient-reported outcome measures were consistently reported across studies, with preservation of wrist range of motion. Complication rates were substantial, with approximately one fifth of wrists experiencing postoperative complications and nearly one fifth requiring reoperation. Most secondary procedures were related to early mechanical instability and consisted of technically oriented revisions rather than implant removal. Conversion to total wrist arthrodesis occurred less frequently. The overall methodological quality of the included studies was moderate. Conclusion: Amandys® pyrocarbon interposition arthroplasty provides clinical improvement and preserves wrist motion but is associated with a relevant and less predictable rate of complications and reoperations. When feasible, proximal row carpectomy remains the preferred motion-preserving procedure. Amandys® arthroplasty should be regarded as a highly selective salvage option, particularly in patients unsuitable for proximal row carpectomy-based solutions, with careful patient selection being essential to optimize outcomes.
