Abstract
The wire mesh reinforcement is provided with a wire mesh lattice having wire-like structures for embedding in a bone cement bed as well as a plurality of spike-like fixing elements which project from the lattice for securement in a bone. The fixing elements serves to anchor the lattice in place before introduction of a bone cement.
Claims13
A wire mesh reinforcement for a bone cement bed comprising
- at least two curved and corrugated structures of wire shape disposed in perpendicular crossing relation to each other to define a hemi-spherical lattice with unobstructed spaces between said structures for receiving bone cement;
- and
- a plurality of fixing elements of spike shape disposed at least along one of said structures for securing said structures to a bone.
A wire mesh reinforcement for a bone cement bed comprising
- a wire mesh hemi-spherical lattice having a plurality of corrugated structures of wire shape disposed in crossing relation forming latitude lines and a plurality of rings secured on latitude lines for embedding in a bone cement bed;
- and
- a plurality of fixing elements of spike shape projecting from said lattice for securement in a bone.
A wire mesh reinforcement for a bone cement bed comprising
- at least two curved and corrugated structures of wire shape disposed in perpendicular crossing relation to each other to define a hemispherical lattice with unobstructed spaces between said structures for bone cement;
- and
- at least one fixing element of spike shape disposed at a pole of said lattice for securing said lattice to a bone for subsequently receiving bone cement.
