摘要:
The invention comprises an implant having a first end section and a second end section, where the first end has a cancellous thread for implantation in a first section of bone and the second end includes expansion slots and barbs or wings, that that resist movement out of a second section of bone. These anchors expand outwardly when a rigid wire, such as a k-wire is fed through a central cannulation in the implant and either the wire expands in diameter or the cannulation decreases in diameter. The implant also includes a collar intermediate to the first and second section which includes one or more surfaces to allow the first section to be screwed into a first bone section.
