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.

Fixation systems and methods of repairing a pars fracture

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.
