INTERBODY IMPLANT WITH INDEPENDENT CONTROL OF EXPANSION AT MULTIPLE LOCATIONS

Expandable spinal interbody implants (10) include a body (11) and at least one extendable support element (22a) connected thereto. Such an implant (10) may include a second extendable support element (22b) and a tool (63) selectively positionable with respect to the implant (10) so as to independently or simultaneously expand both extendable support elements (22a, 22b). In another example, such an implant may include, at each of a first and second location, a respective movable member and a respective locking element. The at least one extendable support element (22a, 22b) may be actuatable to expand so as to induce movement of at least one of the movable members away from the body. The locking elements at each of the first and second locations may be selectively lockable such that, when locked, the locking element restrains movement of the associated movable member at that location away from the body without restraining movement of the other movable member away from the body.
