摘要:
A bone fastener includes a receiver defining a longitudinal axis and extending between a proximal end and a distal end, the proximal end including a first wall and a second wall that define an implant cavity, each wall having a proximal face. At least one of the first wall and the second wall include an extension extending proximally from the proximal face along the longitudinal axis, the extension having a distal end integral with the proximal face and a proximal end including a first locking part configured for fixation with a second locking part of an instrument. A bone penetrating member has a proximal end and a distal end, the proximal end of the bone penetrating member being connected with the distal end of the receiver.

An intervertebral implant comprises a first component and a second component. The second component includes an actuator and a third component comprises a first ramp and a second ramp axially spaced apart from the first ramp. The third component comprises rails including at least a portion of the ramps. At least one of the ramp portions disposed with the first rail has a first height and at least one of the ramp portions disposed with the second rail has a second height. The first height is greater than the second height. The actuator is engageable with the third component to effect axial translation such that the ramps engage at least one of the components between a first configuration and a second configuration. Methods of use are disclosed.
摘要:
An intervertebral implant is provided. The intervertebral implant comprises a first component comprising an outer tissue engaging surface and an inner surface. A second component is connected to the first component, and is relatively moveable thereform. The second component comprises an outer tissue engaging surface and an inner surface. The second component includes an actuator. A third component is disposed for engagement and is movable relative to the first and second components. The third component comprises at least a first ramp and a second ramp axially spaced apart from the first ramp. The actuator is engageable with the third component to effect axial translation of the wedge such that the ramps engage the inner surface of at least one of the first component and the second component to move the components between a first, collapsed configuration and a second, expanded configuration. Methods of use are disclosed.

Embodiments of the invention include expandable implants incorporated into a system for deploying the expandable implants to replace skeletal structures such as one or more vertebrae or portions of the spine or vertebrae. Some embodiments include related methods of implanting devices using deployment systems.
摘要:
Embodiments of the invention include a medical implant having a vertebral body replacement device, alone or in combination with other complimentary elements, configured to deliver one or more therapeutic substances. The one or more therapeutic substances may be contained in the medical implant or be ported to the medical implant.
摘要:
Embodiments of the invention include a device for supplementing or replacing a spinal structure and therapeutically delivering radiation to tissue. Some embodiments include a radiation source and a combination of members surrounding the radiation source that move relative to one another to permit or restrict emission of radiation from the device.
摘要:
A flexible spinal implant for insertion into an intervertebral disc space for sagittal and/or coronal intervertebral stabilization is provided comprising a flexible implant which enables bending of the flexible implant to facilitate insertion of the flexible spinal implant into the disc space via a spinal surgical procedure. The flexible spinal implant comprises a leading end, a trailing end flexibly connected to the leading end, a locking mechanism, wherein the implant is deformable at or about a flexible section to thereby permit a substantially straight entry of the implant into the disc space, and delivered to the selected disc space at a desired insertion angle of approach via a spinal surgical procedure. The implant can have a leading end comprising a curved or bullet shaped configuration, and the flexible section may be comprised of a flexible material or flexible sections which may be lockingly engaged.
摘要:
A spinal rod system includes a first rod and a second rod engaged to a connector with the first and second rods extending axially therefrom in opposite directions from one another. The connector is mountable to a mounting anchor and securable thereto with an engaging member. The connector secures the first rod in the mounting anchor and the connector is clampingly engaged between the engaging member and the first rod. The second rod is engageable in a receiving portion of the connector adjacent to the mounting anchor.
摘要:
A side-loading bone anchor is provided, which may be used in cervical, thoracic, lumbar or sacral areas of the spine or other orthopedic locations. In one embodiment, the anchor includes an anchoring portion, a receiving portion, and an internal piece that is rotatable with respect to the receiving portion at least to a degree. The anchoring portion is attached to a bone. A rod or other elongated support member is received in the receiving portion in contact with the internal piece. The rod and internal piece may be rotated for variability substantially in a plane, and a set screw is threaded into the receiving portion to lock the rod within the receiving portion.
