a first portion fittable with respect to a second portion, said first and
said second portions to form an intervertebral implant shape having
opposing load distribution surfaces shaped for substantially even contact of
adjacent vertebra above and below an intervertebral space for insertion into
said intervertebral space;
a load cell mounted to receive a force of said first portion toward said
second portion; and
information transmission structures associated with said load cell for
transmitting information about a measured force of said first portion toward
said second portion away from said load cell.
27. An intervertebral measuring instrument for use in spine surgery
comprising:
a first portion fittable with respect to a second portion, at least a part
of said first and said second portions to form an intervertebral implant shape
having opposing load distribution surfaces shaped for substantially even
contact of adjacent vertebra above and below an intervertebral space for
insertion into said intervertebral space;
a load cell mounted on at least one of said first and second portions to
receive a force of displacement said first portion with respect to second
portion; and
information transmission structures associated with said load cell for
transmitting information about a measured force of said first portion with
respect to said second portion away from said load cell.
