Efficacy of Selective Arterial Perfusion Combined With Core Decompression in Managing Osteonecrosis of the Femoral Head

At 12 months of follow-up, compared with CD alone, SAP combined with CD demonstrated better clinical performance in nontraumatic ONFH patients at ARCO stages 1-2, accompanied by a higher effective rate, lower femoral head collapse rate, more significant reductions in lesion size and improved hip joint function, while maintaining a comparable safety profile. This combined regimen provides a valuable option for hip-preservation treatment in early-stage ONFH, with potential clinical implications for optimizing minimally invasive intervention strategies.
