Abstract
A spinal implant includes a first member defining a longitudinal axis and including a wall that defines an axial cavity. The first member further defines at least one lateral cavity configured for disposal of an instrument and is oriented transverse relative to the longitudinal axis. A second member includes an axial surface defining gear teeth and being configured for disposal with the axial cavity such that the teeth are offset from the longitudinal axis. The instrument is engageable with the teeth to axially translate the second member relative to the first member. Surgical instruments, systems and methods are disclosed.
Claims20
A spinal implant comprising:
- a first member defining a longitudinal axis and including a wall that defines an axial cavity, the first member further defining at least one lateral cavity configured for disposal of an instrument and being oriented transverse relative to the longitudinal axis;
- a second member including an axial surface defining gear teeth and being configured for disposal with the axial cavity such that the teeth are offset from the longitudinal axis;
- and
- a lock configured to extend through the wall and into a slot in the second member such that the lock simultaneously engages opposing arcuate surfaces of the slot to independently lock the second member relative to the first member,
- wherein the teeth are configured to engage the instrument to axially translate the second member relative to the first member.
A spinal implant comprising:
- a first member defining a longitudinal axis and including a wall that includes a smooth inner surface that defines an axial cavity, the first member further defining at least one lateral cavity oriented transverse relative to the longitudinal axis;
- a second member including an axial surface defining gear teeth and being configured for disposal with the axial cavity such that the teeth are offset from the longitudinal axis;
- and
- a lock configured to extend through the wall and into a slot in the second member such that the lock simultaneously engages opposing concave surfaces of the slot to independently lock the second member relative to the first member,
- wherein the teeth are configured to engage an instrument to axially translate the second member relative to the first member in opposite directions.
A spinal implant comprising:
- a first member defining a longitudinal axis and including a wall that includes a smooth inner surface that defines an axial cavity, the first member further defining at least one lateral cavity oriented transverse relative to the longitudinal axis;
- a first endplate coupled to the first member such that the first endplate is moveable in a plurality of angular orientations relative to the longitudinal axis;
- a second member including an axial surface defining gear teeth and being configured for disposal with the axial cavity such that the teeth are offset from the longitudinal axis;
- a second endplate coupled to the second member such that the second endplate is moveable in a plurality of angular orientations relative to the longitudinal axis;
- and
- a lock that extends through a threaded opening in the wall, the lock being configured for engagement with opposing arcuate surfaces of a slot in the second member to independently fix the second member relative to the first member,
- wherein the teeth are configured to engage an instrument to axially translate the second member relative to the first member in opposite directions.
