摘要:
Devices and methods for replacing one or more spinous processes of a patient include a replacement body with a lamina portion positionable anteriorly toward the spinal canal along with a spinous process portion extending posteriorly from the lamina portion to replace a removed spinous process. Connecting elements extend from opposite sides of the body for connection to the vertebral body with anchors.
摘要:
Posterior spinal stabilization devices and methods include first and second elongate elements engageable along the spinal column and a spinous process replacement body positionable between the elongate elements. Connection mechanisms are provided to adjustably connect the spinous process replacement device to the elongate elements so that the spinous process replacement device can be moved to the desired location between the connecting elements and secured in the desired location.

One technique of the present application includes: evaluating a patient having a previously implanted spinal construct and corresponding spinal fusion from an earlier procedure and determining a spinal segment adjacent to the spinal fusion is degenerating after completion of the earlier procedure. After this determination, the previously implanted spinal construct is augmented by attaching a flexible polymer elongated member to the spinal segment adjacent to the spinal fusion with a bone fastener and by coupling the flexible polymer elongated member to one or more elements of the previously implanted spinal construct. In one form, the elongated member is at least partially comprised of polyetheretherketone.

Devices and methods for spinal stabilization include first and second anchors engageable to respective ones of first and second vertebrae and a connector assembly engageable with the anchors to provide a desired stabilization effect. The connector assembly includes a pair of bumper assemblies extending between the bone anchors and a connecting element extending through the bumper assemblies and connecting the first and second bone anchors to one another.
摘要:
Methods and systems for performing a surgical procedure using implantable sensors are disclosed. The method includes providing one or more implantable sensors, each sensor configured for implantation adjacent to an anatomical feature of a patient; imaging the patient to determine the relative positions of the one or more implantable sensors relative to the anatomical features of the patient; inserting an implant adjacent to at least one of the anatomical features; and tracking the position of the implant relative to the at least one anatomical feature during the inserting of the implant using the implantable sensors.
摘要:
An implant is disclosed and can include a body and a plurality of pellets disposed within the body. The implant can be moved between an unmolded, relaxed configuration wherein the body is not conformed to a bone and a molded, relaxed configuration wherein the body is at least partially conformed to the bone.
摘要:
An interspinous implant kit includes a receiver body and multiple modules. The receiver body is adapted to be implanted between a spinous processes and includes corresponding saddles with an intermediate section therebetween. The intermediate section includes a module-receiving bay. The modules are configured to be interchangeably received in the bay. The first module may have a sensor adapted to generate measurement data indicative of at least one of forces acting on said receiver body and strain when mated to said receiver body. The second and third modules have mechanical material properties that are the of the same type, but different. One of the modules is advantageously mated to the receiver body to form a long-term implant.

A prosthetic device for insertion in a spinal column includes a first, second, and third members. The first member includes an inferiorly extending tab and is of a relatively flexible material. The second member includes a superiorly extending tab and is of a relatively flexible material. The third member defines a superior opening for receiving the inferiorly extending tab and an inferior opening for receiving the superiorly extending tab and is of a relatively stiff material. The device also includes a means for providing a rigid connection of the third member to a vertebra.
摘要:
A surgical implantation procedure and a device for performing same according to which an expandable member is inserted between anatomical structures and expanded in one plane to cause relative movement between the structures. The expansion is terminated when the structures are in a predetermined spatial relationship.
