Abstract

A spacer apparatus for maintaining an interspinous spacing is provided. The spacer apparatus includes a first member and a second member. The first member includes a first body section supporting the upper spinous process, a first upper wing section supporting one side of the upper spinous process, a first lower wing section supporting one side of the lower spinous process, and a protrusion laterally extending from the first body section. The second member includes a second body section having an insertion hole through which the protrusion is inserted, a second upper wing section supporting the other side of the upper spinous process, and a second lower wing section supporting the other side of the lower spinous process.

Dependent claims

A spacer apparatus for maintaining an interspinous spacing, the spacer apparatus comprising:

a first member and a second member,
the first member having:
a first body section located between an upper-side spinous process and a lower-side spinous process so as to support the upper-side spinous process;
a first upper wing section extending upwards from the first body section so as to support one side of the upper-side spinous process;
a first lower wing section extending downwards from the first body section so as to support one side of the lower-side spinous process;
and a protrusion laterally extending from the first body section,
the second member having:
a second body section having an insertion hole through which the protrusion is inserted;
a second upper wing section extending upwards from the second body section so as to support the other side of the upper-side spinous process;
and a second lower wing section extending downwards from the second body section so as to support the other side of the lower-side spinous process.
