Femoral osteotomies for hip joint preservation.
Review in International orthopaedics, 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
purposeFemoral osteotomy represents one of the most distinctive achievements of Japanese orthopaedic surgery in hip preservation. Despite the remarkable advances in total hip arthroplasty (THA), preservation of the native hip joint remains an important therapeutic goal in young and active patients. This review provides a comprehensive overview of femoral osteotomies developed in Japan.
methodsRelevant literature on Japanese femoral osteotomies was reviewed, focusing on their historical development, therapeutic principles, indications, clinical outcomes, and future perspectives.
resultsJapanese surgeons developed two distinctive femoral osteotomy procedures, transtrochanteric rotational osteotomy and curved varus osteotomy. These procedures have become important joint-preserving options and are currently performed primarily for osteonecrosis of the femoral head, with selected applications to other hip disorders. Long-term studies have demonstrated favorable outcomes in appropriately selected patients. However, technical complexity, demanding rehabilitation, and the widespread success of THA have limited their global adoption.
conclusionFemoral osteotomy remains a valuable strategy for hip preservation and represents a unique legacy of Japanese hip surgery. Continued technological innovation and effective transmission of surgical expertise will be essential to sustain and further develop this contribution to hip-preserving surgery in the modern arthroplasty era.
