An interbody fusion device includes a base member, a top member, and an expansion mechanism for moving the top member relative to the base member. The expansion mechanism may include a connector drive rod assembly, a gear, a threaded rod, and a support means. The gear ring is coupled to the threaded rod and is rotatable. The expansion mechanism may also include at least one load head coupled to the threaded rod. An alternative interbody fusion device is also disclosed and includes a bottom member, a superior member, and an expansion mechanism for moving the superior member relative to the base member, wherein the expansion mechanism comprises at least one expansion assembly for moving an end of the superior member relative to the bottom member.

Multiple spindle adjustable interbody fusion devices and methods of use

Tissue spacer implants and surgical methods for inserting the implants are disclosed. The implants may include a first cylindrical body with an outer surface, an axially extending hole, and a first end, a second cylindrical body with an outer surface and an axially extending hole, and an adjustment member with an outer surface, an axial hole, and at least one helical slot. The adjustment member axial hole may be adapted to receive the first cylindrical body and the adjustment member may be configured to be inserted into the axially extending hole of second cylindrical body. The implants may also include a travel mechanism for engaging the first cylindrical body, adjustment member, and second cylindrical body along the at least one helical slot to maintain a space between two bodies of tissue.

A horizontal and vertical expandable tissue spacer implants, insertion tools, assembly methods and surgical methods are disclosed. The horizontal expandable tissue spacer implant includes a first lateral member with a first side, a second lateral member with a first side, and an intermediate spacer member. The intermediate spacer member is adapted to cooperatively engage and hold the first side of the first lateral member and the first side of the second lateral member. A vertical expandable tissue spacer implant includes a top member with a bottom surface, a bottom member with a top surface, and an intermediate spacer member with a coupling mechanism. The coupling mechanism cooperatively engages the bottom surface of the top member to the intermediate spacer member and the top surface of the bottom member to the intermediate spacer member.
