Chinese clinical practice guidelines for minimally invasive hip preservation techniques for femoral head osteonecrosis (2025 edition).
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
purposeOsteonecrosis of the femoral head (ONFH) frequently affects young and middle-aged adults and may progress to collapse. This guideline provides evidence-informed, expert-panel recommendations for minimally invasive hip preservation in adults, generally aged 60 years or younger, with early- to mid-stage nontraumatic ONFH.
methodsA multidisciplinary panel formulated nine clinical questions. PubMed/MEDLINE, Europe PMC, and OpenAlex were searched from inception to May 1, 2025. Systematic reviews, clinical trials, observational studies, prognostic cohorts, case series, and relevant guidelines were included. Evidence was graded using the 2009 Oxford Centre for Evidence-Based Medicine framework, and recommendations were finalized through expert consensus. The guideline primarily applies to adults aged ≤ 60 years with glucocorticoid-associated, alcohol-associated, or idiopathic ONFH at ARCO stages I-IIIA.
resultsNine recommendations were developed; all were graded C or D. Individualized ONFH hip-preserving regimens shall be built into dynamic multi-dimensional pathways centered on disease staging with integrated consideration of patient age, lesion classification and personal demands. Asymptomatic hips require imaging-based risk stratification, and surgery is not indicated solely because a lesion is asymptomatic. Routine combined postoperative pharmacological therapy is not supported. Core decompression is mainly indicated for pre-collapse disease and is preferably combined with regenerative or structural augmentation when appropriate. Bone grafting is one of the key methods to reinforce or reconstruct the lateral pillar, though relevant recommendations on bone grafting and surgical approaches are only low-level expert consensus principles. Osteotomy may be considered in selected young patients when sufficient intact weight-bearing surface can be restored. Post-operative evaluation should combine imaging and patient-reported clinical outcomes.
conclusionThese evidence-informed recommendations provide a nonmandatory framework for selected adults with nontraumatic ONFH. Most statements rely on heterogeneous or indirect evidence and should be applied through individualized assessment and shared decision-making.
