摘要： A spinal interbody device (IBD) includes a solid wall that at least partially defines a boundary of the IBD and a porous body connected to the solid wall. The porous body includes a plurality of sections that form at least a portion of both a superior and inferior bone interface side of the IBD. Each section of the porous body has a different porosity than an adjacent section such that the porosities increase toward a center of the IBD.

摘要： A virtual surgical cutting guide may have first and second slots defining first and second axes respectively. The virtual surgical cutting guide may be positioned away from a vertebral body such that the first and second axes intersect at a distal point located in an interior of the vertebral body. The virtual surgical cutting guide may include the virtual surgical cutting guide with first and second cutting instruments. A method of performing a pedicle subtraction osteotomy may include the steps of placing the virtual surgical cutting guide over the first and second cutting instruments.

摘要： An expandable rod system includes a first rod portion having an internal cavity, a second rod portion sealingly positioned within the internal cavity of the first rod portion and moveable in a first axial direction relative to the first rod portion, and an osmotic chamber for receiving an osmotic agent to facilitate movement of the second rod portion to expand the rod system. The rod system includes a lock assembly engageable with the second rod portion to prevent the second rod portion from moving in a second axial direction. The lock assembly includes a tapered ramped portion and a bearing member that is moveable within the tapered ramped portion such that when compression forces are imparted on the second rod portion, the bearing member becomes wedged in the tapered ramped portion.

摘要： A spinal implant that allows for fluid injection of material is disclosed. The implant includes a fitting with a passage and holes that are in fluid communication with the passage. The holes extend through upper and lower surfaces and/or into a central cavity of the implant. The implant allows for material to be introduced into the implant after initial implantation thereof. Methods of implanting the implant are also disclosed.

摘要： Implants including non-resorbable frameworks and resorbable components, as well as methods of use thereof are disclosed. The embodiments include different combinations of a non-resorbable framework (in some case structural and in other cases non-structural), and a resorbable component embedded within and/or around the framework (again, in some cases structural and in other cases non-structural). The disclosed implants provide an efficient means of providing structural support for the vertebral bodies post-implantation, as well as encouraging resorption of the implant and fusion of the associated vertebral bodies without negative side effects and/or failure, such as subsidence of the implant or cracking/fracturing of a portion of the implant when implanted.

摘要： A device for loading bone graft material into a delivery tube is provided herein. The device includes a housing defining a reservoir for receiving bone graft, a magazine at least partially disposed within the housing, and an actuation member coupled to the housing for discharging the bone graft material into the delivery tube. The magazine defines a first chamber and a second chamber and is moveable between a first position in which the first chamber is in communication with the reservoir and a second position in which the second chamber is in communication with the reservoir. The actuation member includes a plunger configured to slide into the first chamber and the second chamber to discharge bone graft material, when bone graft material is contained therein, into the delivery tube. Methods of loading bone graft material are also provided.
