Design features of the rotating head total hip arthroplasty by Weber-Huggler- a forgotten technical solution to reduce wear.
Review in Archives of orthopaedic and trauma surgery, 2025. 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
Total hip arthroplasty (THA) is a very successful operation. Once the problem of implant fixation was solved with the use of bone cement, the next development steps focused on improving the bearing. Weber, a Swiss surgeon, introduced the first modular heads in THA. His design improved reconstruction of the patients' anatomy using various neck lengths, eased revision as well-fixed stems could be preserved, and also reduced wear due to a cylindrical, rotating connection between the head and neck. The features and results of this exceptional design are reviewed. However, as newer material combinations greatly mitigated the problem of wear and as the dimensions of the cylindrical connection limit range of motion, it was supplanted by the nowadays well-established Morse taper connection, which also is less complex to manufacture. As Weber's design was associated with good long-term results, the technical features of this technical solution should not be forgotten.
