A pedicle insulator implant is designed to protect the nerves and surrounding tissue from injury by pedicle screws or other surgical devices and instruments. The implant is configured to shield a fixture, reduce nerve root irritation, and diminish loosening of the fixture, when the fixture is implanted into the void of a target site. The implant includes features for stabilizing and securing the implant within the void at the target site. For example, in one embodiment, the implant includes one or more ridges and one or more teeth sections that stabilize the implant against rotational and extractive forces that could disturb the implant.

An interbody spinal implant including a body portion having a superior side, an inferior side and a lateral side connecting the superior side and the inferior side, at least one of the superior side or the inferior side comprises a bone contacting surface operable to be coupled to an anatomical structure of a patient; and a plurality of uniform features formed in the bone contacting surface, wherein each uniform feature of the plurality of uniform features comprise a planar peak or a round peak and are dimensioned to increase a surface area of the bone contacting surface to promote bone growth.

The present invention provides a method for stabilizing a fractured bone. The method includes positioning an elongate rod in the medullary canal of the fractured bone and forming a passageway through the cortex of the bone. The passageway extends from the exterior surface of the bone to the medullary canal of the bone. The method also includes creating a bonding region on the elongate rod. The bonding region is generally aligned with the passageway of the cortex. Furthermore, the method includes positioning a fastener in the passageway of the cortex and on the bonding region of the elongate rod and thermally bonding the fastener to the bonding region of the elongate rod while the fastener is positioned in the passageway of the cortex.

A stemmed implant system can include a stem component and an accessory component. The stemmed component can include a first portion adapted to be anchored within a medullary canal of a bone and a second portion including a mounting boss defining an inner coupling surface. The accessory component can define an outer coupling surface adapted to engage the inner coupling surface of the mounting boss of the stem component to secure the accessory component to the stem component.

Methods and devices for correcting wear pattern defects in joints. The methods and devices described herein allow for the restoration of correcting abnormal biomechanical loading conditions in a joint brought on by wear pattern defects, and also can, in embodiments, permit correction of proper kinematic movement.

Systems for distracting a facet joint and positioning a permanent implant in the joint are disclosed. The implants serve to retain a distracted position of the facet joint which is achieved with positioning of the leading end of a distraction tool in the facet joint and then distracting or enlarging the joint a desired amount. The permanent implant could be part of the distraction mechanism which can be separated from the delivery tool once the joint has been distracted or an auxiliary implant may be positioned before the distraction mechanism is removed from the distracted joint. The permanent implants can be solid, mechanical devices that may have fixation means thereon to hold them in place or injected fluids such as hydrogels or fluids confined within balloons.

Systems and tools for inserting and securing an implant within the intervertebral space. An intervertebral disc implant with upper and lower bearing members with an articulation interface between the members for providing relative motion therebetween. The implant may be provided with various securing members for fixing the implant within the intervertebral space. A tool may be used to insert the implant, which includes a plurality of shiftable implant engaging members that are shiftable between non-engaging and engaging configurations to alternatively release or hold the implant.

This present invention concerns a transforaminal intersomatic cage for an intervertebral fusion graft, and an instrument and method for implanting the cage, an embodiment of the cage having a body in the shape of a circular arc and comprising a lateral concave surface, a lateral convex surface, a straight upper surface, a straight lower surface and an end wall having at least one hole, called the end hole, designed to receive a rod of an instrument for implanting the cage between the vertebrae, wherein: the end hole has an orientation that is more or less tangential to the circular arc described by the body; the extremity opposite to the end wall of the body includes a return part extending the body toward the centre of the circle on which the circular arc described by the body lies.
