Metallic prosthetic implant for use in minimally invasive acromio-clavicular shoulder joint hemi-arthroplasty
A biocompatible metallic implant apparatus shaped to fit a natural contour of a shoulder joint, the implant having a cobalt-chrome convex outer surface, a porous concave inner surface and blades on the inner surface for insertion into bone. A locking screw through the implant adheres the implant to the shoulder joint.
1 . A biocompatible metallic implant shaped to fit a natural contour of an acromio-clavicular joint of a shoulder, the implant comprising:
a convex highly polished outer surface and a concave porous inner surface;
at least one blade on the inner surface for insertion into bone; and
a screw through a top surface of the implant for assistance in embedding the implant in the joint, the implant adapted for insertion through a minimally invasive anthroscopic type incision.
2 . The biocompatible metallic implant according to claim 1 , wherein the screw is a locking screw positioned through the outer surface of the implant and within an adjacent bone.
3 . The biocompatible metallic implant according to claim 1 , wherein the highly polished outer surface is a cobalt-chrome alloy.
4 . The biocompatible metallic implant according to claim 1 , wherein the highly polished outer surface is a titanium alloy.
5 . The biocompatible metallic implant according to claim 1 , positioned within an acromio-clavicular joint of a shoulder.
6 . The biocompatible metallic implant according to claim 1 , wherein there is a pair of blades on the porous inner surface for insertion into bone.
7 . A biocompatible metallic implant shaped to fit a natural contour of an acromio-clavicular joint of a shoulder, the implant comprising:
a convex highly polished outer surface and a concave porous inner surface of a substantially L-shaped metallic body;
a pair of blades on the inner surface for insertion into bone; and
a screw passing through the outer surface of the implant, the implant adapted for insertion through a minimally invasive orthoscopic type incision.
8 . The biocompatible metallic implant according to claim 7 , wherein the outer surface is a cobalt-chrome alloy.
9 . The biocompatible metallic implant according to claim 7 , wherein the outer surface is a titanium alloy.
10 . The biocompatible metallic implant according to claim 7 , attached to an acromio-clavicular joint of a shoulder with a locking screw drilled through the outer surface of the implant and into adjacent bone.
11 . The biocompatible metallic implant according to claim 7 , wherein the concave porous inner surface is adopted to promote bone growth with adjacent bone tissue.
12 . A biocompatible metallic implant inserted into a natural contour of an acrimio-clavicular joint of a shoulder, the implant comprising:
a convex brightly polished outer surface in contact with the joint and a concave porous inner surface in contact with bone;
at least one blade on the inner surface inserted into the bone; and
a screw passing through an outer surface of the implant and into bone, the implant inserted in place through an arthroscopic type incision.
13 . A biocompatible metallic implant inserted into a natural contour of a joint according to claim 12 , wherein the highly polished outer surface is a cobalt-chrome alloy.
14 . A biocompatible metallic implant inserted in a natural contour of a joint according to claim 12 , wherein there is a pair of blades on the porous unit surface inserted in bone.
15 . A biocompatible metallic implant inserted into a natural contour of a joint according to claim 12 , wherein the highly polished outer surface is a titanium alloy.
