MODULAR DISC DEVICE

摘要

The disclosure generally relates to a modular disc (300) 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 (302) engageable with first and second side members (302,304) . 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 (308) may be located between upper and lower portions of the side members and/or middle member.
