Abstract
An intramedullary nail for treating long bone fractures. The nail includes a proximal portion that may have a plurality of segments. The segments may be rotatable 360 degrees about a longitudinal axis of the nail such that the position of bone screw openings in the segments can be adjusted to a desired orientation. Locking rings or other locking mechanisms may be provided between the segments to lock the segments in place and allow the segments to be unlocked for readjustment of the position of the segments. The bone screw openings may be configured to allow further angular adjustment of the bone screws with respect to the longitudinal axis of the nail. Inserts may be placed within the bone screw openings to support the bone screws in position.
Claims25
A nail comprising:
- a proximal portion and a distal portion, said proximal portion and said distal portion defining a longitudinal axis, wherein said proximal portion comprises a plurality of segments along said longitudinal axis, each of said plurality of segments having an opening;
- wherein at least one of said plurality of segments is rotatable with respect to said distal portion about said longitudinal axis;
- wherein the nail comprises an insert in at least one of the openings for supporting a bone screw.
A nail comprising:
- a proximal portion and a distal portion, said proximal portion and said distal portion defining a longitudinal axis, wherein said proximal portion comprises a plurality of segments along said longitudinal axis, each of said plurality of segments having an opening;
- wherein at least one of said plurality of segments is rotatable with respect to said distal portion about said longitudinal axis;
- wherein said nail further comprises means for locking said at least one rotatable segment for preventing said at least one rotatable segment from rotating with respect to said distal portion;
- and
- wherein said means for locking said at least one rotatable segment comprises a locking ring.
A nail comprising:
- a proximal portion and a distal portion, said proximal portion and said distal portion defining a longitudinal axis, wherein said proximal portion comprises a plurality of segments along said longitudinal axis, each of said plurality of segments having an opening;
- wherein at least one of said plurality of segments is rotatable with respect to said distal portion about said longitudinal axis;
- wherein said plurality of segments comprise a first segment, a second segment, and a third segment;
- wherein the first segment and the second segment each comprise a sidewall defining a chamber;
- wherein the second segment and the third segment each comprise a connector for being received in said chamber;
- and
- wherein the connectors each comprise a ledge, and the chambers each comprise a slot for receiving the ledge.
A nail comprising:
- a proximal portion and a distal portion, said proximal portion and said distal portion defining a longitudinal axis, wherein said proximal portion comprises a plurality of segments along said longitudinal axis, each of said plurality of segments having an opening;
- wherein at least one of said plurality of segments is rotatable with respect to said distal portion about said longitudinal axis;
- wherein said plurality of segments comprise a first segment, a second segment, and a third segment;
- wherein the first segment and the second segment each comprise a sidewall defining a chamber;
- and
- wherein the sidewalls comprise a threaded exterior surface.
An intramedullary nail for treating bone fractures, said intramedullary nail comprising:
- a proximal portion and a distal portion, said proximal portion and said distal portion defining a longitudinal axis, wherein said proximal portion comprises at least one segment that is rotatable with respect to said distal portion about said longitudinal axis;
- and
- means for locking said at least one segment for preventing said at least one segment from rotating with respect to said distal portion;
- wherein said means for locking said at least one segment comprises a locking ring.
