摘要： A spinal implant is provided and includes a body portion defining a longitudinal axis. The body portion includes a distal end portion, a proximal end portion, opposed side surfaces that extend between the distal and proximal end portions, and top and bottom surfaces configured and adapted to engage vertebral bodies. The top and bottom surfaces have a surface roughness between 3-4 μm. A cavity extends through the top and bottom surfaces defining a surface area that is at least 25% of a surface area of the top surface or the bottom surface. First orifices are defined through the top surface and second orifices are defined through the bottom surface. The second orifices are connected to the first orifices by a plurality of channel.

摘要： A method of repairing a pars fracture includes docking a needle guide on a lamina of the pars, inserting a needle at least partially through the needle guide, inserting a stylet at least partially through the needle, inserting a guidewire at least partially through the needle, removing the needle from the needle guide, removing the needle guide, positioning a screw assembly in contact with the lamina and co-axially with the guidewire, rotating an elongated portion of the screw assembly with respect to the lamina to move the screw assembly distally with respect to the lamina such that a distal end of the elongated portion of the screw assembly travels through an interior portion of the pars and into a superior portion of the pars, and approximating the distal end of the elongated portion of the screw assembly and a collar of the screw assembly to approximate the interior portion of the pars and the superior portion of the pars.

摘要： A fixation system for repairing a pars fracture includes a needle guide configured to be docked on a lamina of the pars, a needle, a guidewire, and a screw assembly. A portion of the needle is configured for insertion through a passage of the needle guide. A portion of the guidewire is configured for insertion through a passage of the needle. The screw assembly includes a collar and an elongated portion, the collar being movable with respect to the elongated portion. A portion of the screw assembly is configured to contact the lamina co-axially with the guidewire.
