Abstract
Arthroplasty devices having improved bone in growth to provide a more secure connection within the body. Different embodiments disclosed include devices having threaded intramedullary components, devices configured to receive bone growth promoting substances, devices with resorbable components, and devices configured to reduce shear stress.
Claims20
A femoral implant device for implementation into bone, comprising:
- an elongated shank having an outer surface extending between a proximal end, terminating in a flat surface having an outwardly extending stem, and a relatively narrow distal end;
- at least one inlet aperture located in said flat surface of said proximal end;
- a plurality of outlet openings located along said outer surface;
- and a plurality of channels located within said shank connecting said at least one inlet aperture with said plurality of outlet openings, such that when said device is implanted into a femur, a bone growth promoting substance can be inserted into said at least one input aperture such that said substance can travel through said channels to said outlet openings to promote bone ingrowth between said implant device and the bone.
1 more element
The device of claim, wherein said bone growth promoting substance is selected from the following list:
- TFG-α, β1,-2;
- EGF,IGF-I;
- PGDF;
- FGF;
- IL-I;
- BMP-1,-2,-3,-4,-5,-6,-7,-8,-8B,-9,-12,-13;
- and VEGF.
4 more elements
A prosthetic device for implantation in bone, comprising:
- a body having a first surface for contacting bone and a second surface;
- at least one input aperture located on said second surface;
- a plurality of outlet openings located along said first surface;
- and a plurality of channels within said body, coupling said at least one input aperture with said plurality of outlet openings,
- such that when said device is implanted into bone, a bone growth promoting substance can be inserted into said at least one input aperture such that said substance can travel through said channels within said body to said outlet openings to promote bone ingrowth between said prosthetic device and the bone.
2 more elements
A prosthetic device for implantation into bone, comprising:
- a body having a first surface for contacting bone and a second surface;
- and at least one groove located within said first surface each of which opens to said second surface,
- such that when said device is implanted into bone, a gone growth promoting substance can be inserted into said at least one groove at said second surface such that said substance can travel within said at least one groove on said first surface of said body to promote bone ingrowth between said prosthetic device and the bone.
