Spinal implant system and method

摘要

An extender comprises an outer member including a lateral opening, first and second extensions defining first and second axial cavities, the axial cavities including a first portion, a second portion and a third portion. An inner member includes a body defining a tab, first and second arms having first and second projections. The inner member is configured for axial translation relative to the outer member between a first position, a second position and a third position. The tab is movable into at least one locking cavity of the lateral opening to fix the inner member relative to the outer member. Methods of use are disclosed.

1. An extender comprising:
an outer member defining a longitudinal axis and including a body defining a lateral opening, the outer member further including a first extension defining a first axial cavity and a second extension defining a second axial cavity, each of the axial cavities including a first portion, a second portion and a third portion; and an inner member including a body defining a tab configured for disposal in the lateral opening, the inner member further including a first arm having a first projection disposed for movement within the first axial cavity and a second arm having a second projection disposed for movement within the second axial cavity, wherein the inner member is configured for axial translation relative to the outer member such that the projections are disposable between a first position such that the projections are disposed with the first portions of the respective axial cavity and the outer member is disposed in a non-expanded orientation, a second position such that projections are disposed with the second portions of the respective axial cavity and the outer member is disposed in an expanded orientation, and a third position such that the projections are disposed with the third portions of the respective axial cavity and the outer member is disposed in an expanded orientation, wherein the lateral opening includes a locking cavity comprising a plurality of lock slots such that the tab is movable into the locking cavity to fix the inner member relative to the outer member in each of the positions.
