 the body includes a first plate comprising the first vertebral engaging surface and a second plate comprising the second vertebral engaging surface, the first plate defining a first axis, the second plate defining a second axis, the spinal implant being movable between a closed configuration in which the first axis extends parallel to the second axis and an open configuration in which the first axis extends at an acute angle relative to the second axis;   the surgical site is a vertebral space; and   the spinal implant is delivered into the vertebral space with the implant in the closed configuration, the implant moving from the closed configuration to the open configuration after the spinal implant is delivered into the vertebral space.   
     
     
         26 . A method as recited in  claim 17 , wherein:
 the body includes an opening extending continuously between and through the vertebral engaging surfaces; and   the method further comprises packing the opening with bone graft after the spinal implant is delivered.   
     
     
         27 . A method as recited in  claim 26 , wherein the opening is packed with the bone graft from a trajectory that the spinal implant was delivered along to the surgical site. 
     
     
         28 . A method as recited in  claim 17 , wherein the body includes a first plate comprising the first vertebral engaging surface and a bottom surface opposite the first vertebral engaging surface, the body including a second plate comprising the second vertebral engaging surface and a top surface opposite the second vertebral engaging surface, the body including first and second cavities each extending into the bottom surface and third and fourth cavities each extending into the top surface. 
     
     
         29 . A method as recited in  claim 28 , wherein delivering the spinal implant comprises inserting a male mating portion of an inserter into the first and second cavities and delivering the spinal implant adjacent the surgical site using the inserter. 
     
     
         30 . A method as recited in  claim 28 , wherein delivering the spinal implant comprises inserting a male mating portion of an inserter into the third and fourth cavities and delivering the spinal implant adjacent the surgical site using the inserter. 
     
     
         31 . A method as recited in  claim 28 , wherein the first and third cavities are aligned to define a first female mating portion configured for engagement with a male mating portion of an inserter, the second and fourth cavities being aligned to define a second female mating portion configured for engagement with the male mating portion. 
     
     
         32 . A method as recited in  claim 24 , wherein the body comprises a first aperture extending into the top surface and a second aperture extending into the bottom surface, the first and second apertures defining a passageway positioned between the first female mating portion and the second female mating portion. 
     
     
         33 . A method as recited in  claim 28 , wherein the body comprises a first aperture extending into the top surface and a second aperture extending into the bottom surface, the first and second apertures defining a passageway positioned between the first cavity and the second cavity and between the third cavity and the fourth cavity. 
     
     
         34 . A method comprising the steps of:
 providing a spinal implant comprising a first plate including a first vertebral engaging surface and a bottom surface opposite the first vertebral engaging surface, the spinal implant including a second plate including a second vertebral engaging surface and a top surface opposite the second vertebral engaging surface, a pin extending through the first plate and the second plate such that the first plate is rotatable relative to the second plate about the pin, the spinal implant including a first cavity extending into the bottom surface and second cavity extending into the top surface;   positioning an end of an inserter into the first and second cavities to connect the spinal implant to the inserter; and   delivering the spinal implant into a vertebral space using the inserter.   
     
     
         35 . A method as recited in  claim 34 , wherein:
 the first plate defines a first axis and the second plate defines a second axis, the spinal implant being movable between a dosed configuration in which the first axis extends parallel to the second axis and an open configuration in which the first axis extends at an acute angle relative to the second axis; and   the spinal implant is delivered into the vertebral space with the implant in the closed configuration, the implant moving from the closed configuration to the open configuration after the spinal implant is delivered into the vertebral space.   
     
     
         36 . A method comprising the steps of:
 providing a spinal implant comprising a first plate including a first vertebral engaging surface and a bottom surface opposite the first vertebral engaging surface, the spinal implant including a second plate including a second vertebral engaging surface and a top surface opposite the second vertebral engaging surface, a pin extending through the first plate and the second plate such that the first plate is rotatable relative to the second plate about the pin, the spinal implant including a first cavity extending into the bottom surface and second cavity extending into the top surface, the spinal implant including an opening extending continuously between and through the vertebral engaging surfaces; and   positioning an end of an inserter into the first and second cavities to connect the spinal implant to the inserter;   delivering the spinal implant into a vertebral space using the inserter; and   packing the opening with bone graft after the spinal implant is delivered into the vertebral space.   
     
     
         37 . A method as recited in  claim 36 , wherein:
 the first plate defines a first axis and the second plate defines a second axis, the spinal implant being movable between a dosed configuration in which the first axis extends parallel to the second axis and an open configuration in which the first axis extends at an acute angle relative to the second axis;   the spinal implant is delivered into the vertebral space with the implant in the closed configuration, the implant moving from the closed configuration to the open configuration after the spinal implant is delivered into the vertebral space; and   the opening is packed with the bone graft from a trajectory that the spinal implant was delivered along into the vertebral space.
