Abstract
A repair apparatus for repairing bone defects includes a bioabsorbable scaffold having first and second ends that spans a space between spaced apart first and second bone fragments. The first end of the scaffold envelops an end of the first bone fragment and the second end of the scaffold envelops an end of the second bone fragment.
Claims20
A repair apparatus for repairing bone defects consisting of spaced apart first and second bone fragments of a bone, the repair apparatus comprising:
- a bioabsorbable scaffold having first and second ends spanning the space between the spaced apart bone fragments, wherein the first end of the scaffold envelops an end of the first bone fragment and the second end of the scaffold envelops an end of the second bone fragment;
- a first screw fixing the scaffold to the first bone segment;
- and
- a second screw fixing the nail to the second bone segment.
A method of repairing a bone defect comprising:
- manufacturing a scaffold with first and second sockets at first and second ends thereof;
- positioning the scaffold in a space between first and second bone fragments of the critical bone defect;
- inserting an end of the first bone fragment into the first socket defined at a first end of the scaffold;
- inserting an end of the second bone fragment into the second socket defined at a second end of the scaffold;
- and
- pressing an intramedullary nail through the scaffold and into axial cavities in the first and second bone fragments.
A repair apparatus for repairing bone defects consisting of spaced apart first and second bone fragments of a bone, the repair apparatus comprising;
- a scaffold extending from an end of the first bone segment to an end of the second bone fragment, the scaffold having a first socket at a first end thereof extending over and enveloping a portion of the first bone fragment and having a second socket at a second end thereof extending over and enveloping a portion of the second bone fragment, and;
- a fastener extending through at least one of the first and second sockets into the corresponding first or second bone fragment.
