| 摘要 |
<p>The invention relates to an artificial intervertebral disc comprising housing members (12,14) including spaced inner surfaces (16,18) facing each other and oppositely facing outer surfaces (20,22) for engaging spaced apart intervertebral surfaces; and self adjusting bearing means (23) operatively disposed between said inner surfaces for moving relative to said housing members to adjust and compensate for vertebral disc motion, further including load sharing means (32,34) disposed between said inner surfaces and about at least a portion of said bearing means for sharing absorption of compressive loads with said bearing means while limiting the relative movement of said housing members.
