A system for use in a laminoplasty procedure, the system comprising: a laminal implant (10, 110) comprising a first body (20, 120) and a second body (30, 130), the first (20, 120) and second (30, 130) bodies adapted to slide relative to one another to expand or compress the implant (10, 110); and an implantation instrument (150, 250), characterized in that the implantation instrument (105, 250) comprises: a shaft (155, 255) having a longitudinal length, a proximal end, a distal end and a hollow throughbore along at least a portion of its length; a handle (170, 270) positioned on the proximal end of the shaft; an actuator rod (165, 265) having a proximal portion and a distal portion, the actuator rod being positioned within the hollow throughbore of the shaft (155, 255); a knob (160, 260) engageable with the proximal portion of the actuator rod (165, 265); a first connector (183, 283) engageable with the distal portion of the actuator rod (165, 265); and a second connector (182, 282) fixedly secured to the distal end of the shaft (155, 255), wherein one of the first or second connectors (183, 283, 182, 282) is removeably coupleable to one of the first (20, 120) or second bodies (30, 130), and the other of the first or second connectors (183, 283, 182, 282) is removeably coupleable to the other of the first (20, 120) or second (30, 130) bodies, wherein actuation of the knob (160, 260) slides at least one of the first (20, 120) or second (30, 130) bodies relative to the other. a laminal implant (10, 110) comprising a first body (20, 120) and a second body (30, 130), the first (20, 120) and second (30, 130) bodies adapted to slide relative to one another to expand or compress the implant (10, 110); and an implantation instrument (150, 250), characterized in that the implantation instrument (105, 250) comprises: a shaft (155, 255) having a longitudinal length, a proximal end, a distal end and a hollow throughbore along at least a portion of its length; a handle (170, 270) positioned on the proximal end of the shaft; an actuator rod (165, 265) having a proximal portion and a distal portion, the actuator rod being positioned within the hollow throughbore of the shaft (155, 255); a knob (160, 260) engageable with the proximal portion of the actuator rod (165, 265); a first connector (183, 283) engageable with the distal portion of the actuator rod (165, 265); and a second connector (182, 282) fixedly secured to the distal end of the shaft (155, 255), a shaft (155, 255) having a longitudinal length, a proximal end, a distal end and a hollow throughbore along at least a portion of its length; a handle (170, 270) positioned on the proximal end of the shaft; an actuator rod (165, 265) having a proximal portion and a distal portion, the actuator rod being positioned within the hollow throughbore of the shaft (155, 255); a knob (160, 260) engageable with the proximal portion of the actuator rod (165, 265); a first connector (183, 283) engageable with the distal portion of the actuator rod (165, 265); and a second connector (182, 282) fixedly secured to the distal end of the shaft (155, 255), wherein one of the first or second connectors (183, 283, 182, 282) is removeably coupleable to one of the first (20, 120) or second bodies (30, 130), and the other of the first or second connectors (183, 283, 182, 282) is removeably coupleable to the other of the first (20, 120) or second (30, 130) bodies, wherein actuation of the knob (160, 260) slides at least one of the first (20, 120) or second (30, 130) bodies relative to the other.
