Abstract
The present invention discloses fusion systems and methods of assembly and use. The fusion systems include a first fastener, a second fastener, and an elongate member with a first end and a second end. The first end being secured to the first fastener and the second end being secure to the second fastener. The method of assembling a fusion system and methods of using the fusion systems are also disclosed.

A fusion system, comprising:
- a first fastener comprising a first head with a first slot, a first shaft and a first neck coupling the first head to the first shaft, and wherein the first head comprises a body portion defining an interior surface and a top surface, and a base portion extending below the body portion defining an concave interior surface defined by a first radius, wherein the interior surfaces of the body portion and first base portion of the first head cooperatively forming a first cavity, and wherein the first slot extends through the body portion from the top surface thereof and through a portion of the base portion to the first cavity;
- a first locking cap comprising a bottom surface with a concave first recess defined by a second radius, the first locking cap threadably engaged with the body portion of the first head within the first cavity;
- a second fastener comprising a second head with a second slot, a second shaft and a second neck coupling the second head to the second shaft, and wherein the second head comprises a body portion defining an interior surface and a top surface, and a base portion extending below the body portion defining a concave interior surface defined by a third radius, wherein the interior surfaces of the body portion and the base portion of the second head cooperatively forming a second cavity, and wherein the second slot extends through the body from the top surface thereof and through a portion of the base portion to the second cavity;
- a second locking cap comprising a bottom surface with a concave second recess defined by a fourth radius, the second locking cap threadably engaged with the body portion of the second head within the second cavity;
- and
- an elongate member comprising a first spherical end, a second spherical end, and a coupling shaft extending between the first and second spherical ends,
- wherein the first spherical end of the elongate member is secured to the first head of the first fastener within the first cavity via the first locking cap, and the second spherical end of the elongate member is secured to the second head of the second fastener within the second cavity via the second locking cap,
- wherein the first spherical end is defined by a fifth radius and includes a diameter that is larger than a diameter of the coupling shaft, and the second spherical end is defined by a sixth radius and includes a diameter that is larger than a diameter of the coupling shaft,
- wherein the diameter of the first spherical end is larger than a width of the first slot, and the diameter of the second spherical end is larger than a width of the second slot, and
- wherein the fifth radius of the first spherical end is larger than the first radius of the first head and the second radius of the first locking cap, and wherein the sixth radius of the second spherical end is larger than the third radius of the second head and the fourth radius of the second locking cap.
