摘要：
An intervertebral disc implant with upper and lower bearing members with an articulation interface between the members for providing relative motion therebetween. In one form, a securing member with an elongate shaft and a bone-engaging member on the shaft is disposed on one of the bearing members. The bone-engaging member is deployable into a bone-engaging position via rotational displacement of the shaft. In another form, a bone-engaging member is deployable via an actuator inserted into the implant body. In another form, the securing member secures an intervertebral implant in intervertebral space via deformation of the securing member causing a bone-engaging member of the securing member to be deployed into contact with an adjacent vertebra.
