A surgical kit comprising:
- a fixation device configured to be implanted into the scaphoid and lunate of a patient in need and comprising a first plate having inward and outward faces and configured to be implanted into the scaphoid and a second plate having inward and outward faces and configured to be implanted into the lunate, wherein said inward faces of the first and second plates are coupled together by a lateral, rotatable, rod having first and second ends individually coupled to the first and second plates, wherein said first plate comprises a first hole and the second plate comprises a second hole laterally aligned with said first hole, wherein said first and second holes comprise a larger perimeter than a cross-section of the rod, wherein the rod's first and second ends are passed through said first and second holes respectively and are individually coupled to the outward faces of the first and second plates respectively;
- and a cutting jig having an aperture having an outline of the entire fixation device and configured to allow a health provider to cut the shape of the fixation device into the scaphoid and lunate.
A surgical kit for implanting a fixation device into the scaphoid and lunate of a patient in need comprising:
- a fixation device having first and second plates connected by a rotatable rod having first and second end pieces, wherein said first plate is configured to be entirely implanted into the scaphoid and said second plate is configured to be entirely implanted into the lunate, wherein said first plate comprises a first hole and the second plate comprises a second hole laterally aligned with said first hole, wherein said first and second holes comprise a larger perimeter than a cross-section of the rod, wherein said rod is passed through said first and second holes such that said first and second end pieces are respectively positioned inside a hollowed out section within the first and second plates, such that the end pieces are allowed to rotate within said hollowed out section;
- and a cutting jig having an aperture having an outline of the entire fixation device and configured to allow a health provider to cut the shape of the fixation device into the scaphoid and lunate.
