Introduction
ONFH, debilitating disease
OSTEONECROSIS OF THE FEMORAL HEAD
Osteonecrosis of the femoral head (ONFH) is a rapidly progressive and debilitating disease [Non-vascularized bone grafting (NVBG) is a viable treatment for pre- and early post-collapse ONFH [The concept of radiomics has emerged as a promising approach to medical imaging with the rapid development of medical artificial intelligence technology [Our institution has been performing NVBG using the Phemister procedure and lightbulb procedure, with a large number of cases, detailed clinical and radiographic data, and medium to long-term follow-up. Therefore, we developed a visual and quantitative assessment approach using data from patients and evaluated its performance internally. Our study aims to provide valuable insights into the optimal selection and efficacy of NVBG procedures for hip preservation using CT radiomics and clinical predictors. We seek to determine suitable patients for hip preservation with NVBG, to identify the most appropriate procedure, and to explore strategies to improve the success rate of hip preservation.
