摘要： An intramedullary assembly for intraosseous bone fusion includes a hybrid screw member and a lag screw member. The hybrid screw member is aligned along a longitudinal axis, and includes a first shaft, a threaded portion, and a head portion having a first internal surface of a first spherical radius and a second tapered internal surface of a second radius. The first internal surface is coupled to the second internal surface to enclose a bore extending through the head portion along a bore axis. The lag screw member includes a second shaft, a bulbous portion, and a threaded portion. The lag screw member is adapted to be inserted into bore and forms an acute angle with the longitudinal axis.
