Abstract
A bone fixation system includes a bone fastener and a tower including a frangible or detachably linked distal section with a thread formed on an inner surface thereof, the tower having at least one flexible section and at least one rigid section to accommodate and/or mitigate tower interference and/or collision during surgical procedures. The distal section can desirably be separated and/or detached from the tower to function as a head locking unit of the bone fixation assembly, with the detached distal section capable of accommodating set screws, fixation rods and/or other spinal hardware.
Claims30
A bone fixation system, comprising:
- a bone fastener having an externally threaded shank and a generally spherical head;
- a tower having a tower body with at least one flexible section and at least one rigid section;
- a connection element attached to the tower body by a frangible linkage, the connection element having a distal opening sized to accommodate the shank of the bone fastener, the connection element further having an internal threadform formed on an inner surface therein;
- and
- a set screw having an external set screw thread configured to mate with the internal threadform of the connection element.
A bone fixation system, comprising:
- a bone fastener having an externally threaded shank and a generally spherical head;
- a tower having a tower body with at least one flexible section and at least one rigid section, at least a portion of the tower body including an internal tower thread;
- a connection element attached to the tower body by a frangible linkage, the connection element having a distal opening sized to accommodate the shank of the bone fastener, the connection element further having an internal threadform formed on an inner surface therein, the internal threadform extending across the frangible linkage and mating with the internal tower thread;
- and
- a set screw having an external set screw thread configured to mate with the internal threadform of the connection element.
A bone fixation system comprising:
- an elongated tower body with at least one flexible section and at least one rigid section;
- a screw head housing element attached to the tower body by a frangible linkage, the screw head housing element having a distal opening and an internal threadform formed on an inner surface therein;
