Potential efficacy and mechanisms of icariin for the animal model of osteonecrosis of the femoral head
Abstract
Introduction Icariin (ICA), one of the main active components of Epimediumis, is reported to revere osteonecrosis of the femoral head (ONFH). The aim of this study is to further explore the mechanisms and efficacy of ICA in animal models of ONFH and simultaneously analyze methodological issues in the field of researches. Methods According to the established search strategy, we searched 14 studies from eight databases from their inception dates to November 2024. The CAMARADES 10-item checklist was utilized to evaluate the methodological quality of the stuies and Rev-Man 5.3 software to analyze differences in outcome indicators. Results The quality score for the included articles ranges from 1/10 to 6/10 with an average of 4.5 and the defects in aspects of blinding assessment of outcome, randomization and sample size calculation are the main losing points. Compared with the control group, 10 stuies reported ICA could partially improve bone pathology including reducing the empty of bone lacunae, maturing osteoblasts of ONFH and decreasing chondroid bone matrix and fibrous connective tissue. Eight stuies indicates that ICA could improve bone-related parameters under imageology including F-BMD, Tb.N, Tb.Th, BV/TV and Tb. Sp. Discussion The preclinical systematic review provided preliminary evidence that ICA partially reversing ONFH in animal models probably via promoting angiogenesis, anti-apoptosis, and regulating the activities of osteoblasts and osteoclasts. Randomization,…
How strong is the evidence?
Evidence Hub reads this as a review, done in animal, not in people. Its evidence level is 5 of 5 (Very low · case / narrative / animal / in vitro / in silico). Case reports, narrative reviews, and animal, cell or computer-model studies give the weakest evidence for human health.
