Research Progress of Injectable Hydrogels Targeting Specific Pathogenesis for Osteonecrosis of the Femoral Head.
Review in International journal of nanomedicine, 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
Osteonecrosis of the femoral head (ONFH) remains a significant clinical challenge in orthopedics, characterized by the poor self-regenerative ability of necrotic bone tissue. Without timely and effective intervention, over 70% of affected patients will eventually suffer from femoral head collapse and require total hip arthroplasty(THA). ONFH arises from different pathways and causes, including traumatic vascular disruption and nontraumatic factors such as steroid-induced ONFH(SONFH) and alcohol-induced ONFH(AIONFH) . Based on these complex pathways, injectable hydrogels have emerged as a minimally invasive therapeutic option for targeted treatment. Herein, this review systematically assesses the strategically designed hydrogels targeting specific pathogenic pathways of ONFH to prevent structural collapse. This review mainly discusses the advantages of injectable hydrogel in stimulating angiogenesis and neovascularization to restore blood supply; facilitating anti-inflammatory modulation to foster a pro-regenerative microenvironment; enhancing bone mineralization through osteoconduction-osteoinduction mechanism; and regulating bone resorption. Additionally, it analyzes various injectabl hydrogel formulations for targeting distinct etiologies, along with their associated clinical studies, and offers recommendations for the future. This review establishes a targeted design for hydrogels that mimic ONFH pathological characteristics, providing a framework for developing effective, minimally invasive strategies that prevent or delay joint replacement.
