摘要： A bone fusing implant device includes an elongated body extending along a longitudinal direction. The elongated body includes a first segment having an outer surface with cortical threads, a second segment having an outer surface with cancellous threads, a top segment and a bottom segment. The first segment is adjacent to the second segment along the longitudinal direction and is configured to engage a cortical bone with the cortical threads and the second segment is configured to engage a cancellous bone with the cancellous threads. The elongated body has one or more elongated fusing gutters extending along the longitudinal direction on an outer surface of the elongated body covering the first and second segments, a central opening extending along the longitudinal direction through the elongated body's center and one or more through-openings that extend horizontally and intersect with the one or more fusing gutters.
