Claim:
1. A method for rigidly fixing one or more fragments of a pars interarticularis to one another comprising: providing a plate having a continuous, unbroken elongate peripheral rim having an outer edge and an inner edge, the inner edge enclosing an open area therewithin, said continuous, unbroken elongate peripheral rim defining a pedicle plate section and a lamina plate section, the open area defining a crescent-shaped pedicle screw receiving hole having a closed proximal portion bounded by the inner edge of the peripheral rim and a narrowed open neck portion that opens into a lamina open area, said crescent-shaped pedicle screw receiving hole and said lamina open area in fluid communication with each other through said open neck portion; placing said plate over a single lamina having a bone fracture that divides a pars area of the lamina into fractured pieces; exposing said bone fracture under said open area; inserting a pedicle screw through the pedicle screw receiving hole to fix said plate to a pedicle; inserting at least one lamina screw through the lamina plate section; rigidly fixing the pedicle to the lamina with said plate to close and fasten the fractured pieces together; and facilitating healing of the fracture by allowing access to the fracture through the open area.
