Abstract
A fastening device for compressing first and second bones together includes a first member configured to extend entirely through the first bone and having a shaft that includes a distal threaded portion and an unthreaded portion. The threaded portion has an outer diameter that is not larger than the diameter of the unthreaded portion. A second member has a first threaded portion for securing to the second bone and a second threaded portion for engaging the threaded portion of the first member while the first member extends entirely through the first bone to secure the first and second members together and compress the first and second bones.
Claims40
A fastening device for compressing first and second bones together comprising:
- a first member configured to extend entirely through the first bone and including a shaft having a threaded portion and an unthreaded portion, the threaded portion having an outer diameter that is not larger than the diameter of the unthreaded portion;
- and
- a second member having a first threaded portion for securing to the second bone and a second threaded portion for engaging the threaded portion of the first member while the first member extends entirely through the first bone to secure the first and second members together and compress the first and second bones.
A fastening device for compressing first and second bones together comprising:
- a first member having a head and a shaft extending from the head, the shaft including threads for engaging the first bone, the head having a first cooperating member;
- and
- a second member having a head and a shaft extending from the head, the head having a second cooperating member that is engageable with the first cooperating member of the first member to compress the first and second bones, the shaft including threads for engaging the second bone.
A method of compressing first and second bones together comprising:
- providing a first member having a shaft including a threaded portion and an unthreaded portion, the threaded portion having an outer diameter that is not larger than an outer diameter of the unthreaded portion;
- providing a second member having a first threaded portion and a second threaded portion;
- threading the first threaded portion of the second member into the second bone to secure the second member to the second bone;
- forming a passage through the entire first bone having a diameter that is greater than the diameters of the shaft of the first member;
- inserting the first member through the passage such that the shaft of the first member extends entirely though the first bone;
- and
- threading the threaded portion of the first member into the second threaded portion of the second member to compress the first and second bones together.
A method of compressing first and second bones together comprising:
- providing a first member having a head and a shaft extending from the head, the head having a first cooperating member, the shaft including threads for engaging the first bone;
- providing a second member having a head and a shaft extending from the head, the head having a second cooperating member that is releasably engageable with the first cooperating member of the first member, the shaft including threads for engaging the second bone;
- threading the threads of the first member into the first bone to secure the first member to the first bone;
- threading the first threaded portion of the second fastener into the second bone to secure the second member to the second bone;
- and
- securing the cooperating members of the first and second members together to compress the first and second bones together.
