摘要:
Disclosed are surgical tools, tool sets and methods for percutaneously accessing and preparing treatment sites within the spine for subsequent treatment procedures. The treatment site may be an inter-vertebral motion segments in the lumbar and sacral regions of the spine. The tool set may comprise introducer tools and bone dilators for accessing and tapping into a targeted site, such as, for example, the anterior surface of the S1 vertebral body. The tool set may also comprise cutters and extractors for preparing the treatment site for subsequent treatment procedures. The tool set may additionally comprise a bone graft inserter, an exchange system, and/or a temporary distraction tool for further preparing the treatment site for subsequent treatment procedures.

The invention provides an implantable spinal distraction/fusion rod with varied thread pitch and diameters along different portions of its length that it is capable of distracting two or more vertebral bodies relative to each other and/or facilitating the procedure of fusing the vertebral bodies together from within the spine. The present invention also provides for methods of using the rod to distract and/or fuse two or more vertebral bodies from within the spine.

Surgical tools, tool sets and methods for percutaneously accessing and preparing treatment sites within the spine. A method of treating the spine, comprising the steps of percutaneously accessing an anterior target site on the surface of the sacrum, forming a lumen from the access site through the sacrum, through a disc and into at least one vertebra, advancing a fusion device comprising a distal portion, a proximal portion and an intermediate portion between the distal and proximal portion through the anterior target site on the surface of the sacrum and into the spine, rotating the distal portion of the device into a superior vertebral body and the proximal portion of the device in an inferior vertebral body to increase a distance between the superior and inferior vertebral bodies, and inserting through a percutaneous access site a posterior column fixation device into the spine.

An alignment jig that creates a plurality of parallelograms may be used to align an external alignment line with an internal target path. The internal target path is within the patient's body and may be defined by two guide pin tips. The alignment jig may be created so that it creates the external alignment line to be co-linear with the internal target path or the external alignment line may be parallel to the internal target path by offset a distance from being co-linear. The external alignment line may be used in the provision of therapy such as the delivery of a screw to a precise location in the provision of therapy to a portion of the spine.
摘要:
A device for treating a facet joint of a patient, the facet joint including opposing, superior and inferior faces. The device includes a superior component and an inferior component each defining an anchoring surface configured to engage bone at a face of the facet joint and an articulating surface. The device is configured for percutaneous insertion into the facet joint, with the articulating surfaces abutting one another in a sliding interface. One or more instruments are included with the device as part of a percutaneous implantation kit, such as a dilator, a guide wire, and a sheath.
