Traditional brain connectivity studies have focused mainly on structural connectivity, often relying on tractography with diffusion MRI (dMRI) to reconstruct white matter pathways. In parallel, studies of functional connectivity have examined correlations in brain activity using fMRI. However, emerging methodologies are advancing our understanding of brain networks. Here we explore advanced connectivity approaches beyond conve...

Purpose Osteonecrosis of the femoral head (ONFH) requires effective removal of necrotic tissue to improve surgical outcomes. Conventional curettes often fail to address clinical needs due to limitations in cutting capability, strength, and adaptability. This study introduces a disposable multi-angle eccentric curette designed to enhance necrotic bone removal during core decompression surgery. Methods The curette was designed w...
