An adjustable intervertebral implant for implantation into a patient's spine in-between first and second adjacent or neighboring vertebrae. The implant may include one or more of the following features: (i) inner and outer members coupled by a radiographically imagable expansion ring, (ii) detachable endplates coupled to the implant via a polygonal press-fit coupling interface that accommodate a range of lordotic endplates to be applied to the implant using any surgical approach, (iii) an interference pre-loaded set screw for selectively locking the height of the construct, (iv) a radiographically imagable marker for determining the expansion of the implant, and (v) an asymmetric thread coupling between the expansion ring and the inner member.

Surgical instrument

An adjustable intervertebral implant () for implantation into a patient's spine in-between first and second adjacent or neighboring vertebrae. The implant may include one or more of the following features: (i) inner () and outer () members coupled by a radiographically imageable expansion ring (), (ii) detachable endplates () coupled to the implant via a polygonal press-fit coupling interface that accommodate a range of lordotic endplates to be applied to the implant using any surgical approach, (iii) an interference pre-loaded set screw () for selectively locking the height of the construct, (iv) a radiographically imageable marker () for determining the expansion of the implant, and (v) an asymmetric thread coupling () between the expansion ring and the inner member.

An apparatus for use with a spinal implant includes a handle structure with a passage. A shaft with a screw thread is moveable within the passage in the handle structure. A pusher block is linked to the shaft, and has a forward surface configured to engage the spinal implant. A screw-threaded clutch member is supported on the handle structure for movement into and out of engagement with the screw thread on the shaft.

Implant insertion apparatus and method of use

An apparatus for use with a spinal implant includes a handle structure with a passage. A shaft with a screw thread that is moveable within the passage in the handle structure. A pusher block is linked to the shaft, and has a forward surface configured to engage the spinal implant. A screw-threaded clutch member is supported on the handle structure for movement into and out of engagement with the screw thread on the shaft.

A system for performing a less invasive surgical procedure and, in particular, devices and methods for spinal fixation. The system comprises dilation tool(s), at least one working/insertion cannula, a plurality of screws, at least one fixation rod for connecting the screws, and a rod inserter. The dilation tool(s) may be used to dilate an incision made in a patient to form an opening. An insertion cannula may be attached to a screw and inserted into the opening. The screws may be polyaxial screws and may be inserted into the vertebrae using a screwdriver. An operator may then move the insertion cannula to manipulate a head portion of the screws such that the head portions may be aligned to receive a fixation rod. A rod inserter may be used to insert a fixation rod into the head portions.

Less invasive surgical system and methods

Tools for use in the creation of cavities in bones. The tools include a probe, a cannula that provides percutaneous passageway to the interior of the treated bone, a bone tamp, and a system for delivering bone filler material into the cavity. The bone tamp has a shaft that is inserted into the bone through the cannula. The end of the shaft that is inserted into the bone may have a flapper tip that extends out of axial alignment with the shaft upon deployment by the physician. Once the tip is deployed, the bone tamp can be rotated to form the cavity. The cavity may then be treated with a medicament, filled with bone filler material, or both. Other tools and materials described herein may be used to lift or restore the treated bone closer to its natural anatomy.

Tools and methods for creating cavities in bone

The present invention is directed to a surgical drill guide. The drill guide may include a first drill guide body having a distal end for placement substantially adjacent a bone, a second drill guide body slidable with respect to the first drill guide body and having a proximal end for contacting a portion of a drill bit, a handle associated with at least one of the first drill guide body and the second drill guide body, and a detent mechanism for releasably retaining the position of the first drill guide body with respect to the second drill guide body in predefined increments. Additionally or alternatively, the drill guide may include a locking member movable between a first position where it substantially prevents sliding of the second drill guide body with respect to the first drill guide body, and a second position where it permits sliding of the second drill guide body with respect to the first drill guide body. The locking member may be resiliently biased to the first position. Other features for improving the drill guide are disclosed and claimed as well.
