Abstract
The present application is directed to vertebral rods and methods of use. In one embodiment, the rod includes upper and lower sections that are separated by an intermediate section. The intermediate section may include one or more members, and may have a variety of configurations. An elastic member may be positioned within the intermediate section. The intermediate section and the elastic member may provide for variable resistance during movement of the upper and lower sections. In one embodiment, the resistance increases the further away the upper and lower sections move from a first orientation. In one embodiment, the extent of movement of the upper and lower sections is limited.
Claims33
A vertebral rod comprising:
- a first elongated section;
- a second elongated section;
- an intermediate section positioned between the first and second sections, the intermediate section comprising a member with a turn and an upper section and a lower section;
- and
- an elastic member positioned within the intermediate section;
- the intermediate section and elastic member configured to provide variable resistance to movement of the first and second sections.
A vertebral rod comprising:
- a first section;
- a second section;
- an intermediate section positioned between the first and second sections, the intermediate section comprising a member with a turn and an upper section and a lower section;
- and
- an elastic member positioned within the intermediate section between the upper and lower sections;
- the intermediate section movable between a first position with the upper and lower sections spaced a first distance apart, and a second position with the upper and lower sections spaced a second, different distance apart, the elastic member applying a force in the second position to return the intermediate section towards the first position.
A vertebral rod comprising:
- an upper section;
- a lower section;
- an intermediate section extending between the upper and lower sections, the intermediate section comprising first and second members;
- an interior section formed between the first and second members;
- and
- an elastic member positioned within the interior section;
- the first and second members and the elastic member providing resistance to movement of the upper and lower sections.
A vertebral rod comprising:
- a first section;
- a second section;
- and
- an intermediate section positioned between the first and second sections, the intermediate section comprising a member comprising an overlapping configuration and an elastic member;
- the intermediate section and elastic member configured to provide variable resistance to movement of the first and second sections.
