Abstract
The disclosure generally relates to a modular disc that is insertable by sections into a disc space located between vertebral bodies. The primary segments of the modular disc are one or more middle members engageable with first and second side members. The first and second side members are successively inserted into and positioned in the disc space one at a time. The middle member is then slidably engaged on rails extending from the respective first and second side members. Eventually, the middle member is moved along the guides and positioned between the respective first and second side members and the guides or rails are detached. Optionally, a cushioning and/or biasing member may be located between upper and lower portions of the side members and/or middle member.

33. A method of inserting a spinal disc between vertebral bodies, the method comprising:
-
inserting a first side member into a first portion of a disc space located between the vertebral bodies, the first side member having an engagement member with a first engagement portion and a second engagement portion, the first engagement portion coupled to the first side member and locatable within the disc space, the second engagement portion extending from the first engagement portion and protrudable from the disc space in a first direction;
inserting a second side member into a second portion of the disc space, the second side member having an engagement member with a first engagement portion and a second engagement portion, the first engagement portion coupled to the second side member and locatable within the disc space, the second engagement portion extending from the first engagement portion and protrudable from the disc space in substantially the first direction;
slidably engaging a middle member with the second engagement portions of the first and second side members;
sliding the middle member along the second engagement portions of the first and second side members;
sliding the middle member along the first engagement portions of the first and second side members until the middle member is located within the disc space; and
detaching the second engagement portions of the first and second side members. - View Dependent Claims (34, 35, 36)
