Laminoplasty Hinges

A surgical implant device configured to be adjustable in size and orientation so as to be adaptable to a surgical site, the implant device, comprising:

• a base and an extension adjustably connectable to the base to enable adjustment of both planar and angular orientation of the surgical implant device;
• the base having a seat and a back extending from the seat;
• and
• the extension having an elongated body with a head at an end of the elongated body of the extension, the head being pivotally or movably mountable or both to the extension to permit a plurality of different configurations of the implant device.

A surgical implant device configured for use at complete cut location of an open door laminoplasty surgical site to span between a lamina of a vertebrae and an open mass of a vertebrae, the implant device configured to be adjustable in size and orientation so as to be adaptable to the open door laminoplasty surgical site at the time of surgery, the implant device, comprising:

• a base and an extension adjustably connected to the base to enable adjustment of planar orientation or angular orientation or both of the surgical implant device,
• the base having a seat and a back having a length axis and extending from the seat in a reclined relationship, a pair of spaced apart and aligned elongate slots located at a distal end of the back of the base, the elongate slots having aligned length axes that are located along and aligned with the length axis of the back, a hook configured to be able to hook onto the lamina of the vertebrae and a foot configured to be able to be able to buttress against the lateral mass of the vertebrae, and
• the extension having an elongated body with a head at an end of the elongated body of the extension, the head having oppositely extending arms, the head of the elongated body of the extension being positionable between the slots of the base so that the arms of the head of the elongated body span between the slots of the back of the base,
• wherein when the head of the extension is positioned between the slots of the base when the implant device is installed in a patient during surgery, the head of the extension is freely pivotable within the slots of the base to permit a plurality of angular orientations of the implant device and the head is movable along the elongate length of the slots to provide adjustment of the planar orientation of the implant device based on the location of the head along the elongate length of the slots.
