Abstract
A medical apparatus having a bar, the bar having a slot extending laterally along the bar; and a plurality of hooks, wherein the bar is an arch bar that is configured to be attached to a mandible or a maxilla. Such medical apparatuses may also have a plurality of arch bar fasteners, wherein each arch bar fastener is a bone screw having a threaded shaft and a compound head, the compound head having a threaded bore configured to receive a set screw. The medical apparatus may be used in methods to fixate a maxillary or mandibulary arch, or to aid in reducing a fracture of the mandible or maxilla.
Claims11
A medical apparatus comprising:
- a first curved arch bar configured to be placed on a mandible, the first arch bar including a first longitudinal axis, a plurality of elongated first slots extending laterally along the first longitudinal axis and defined by a plurality of first lateral supports and a plurality of integrally formed first hooks, each of the first hooks being free of holes;
- a second curved arch bar configured to be placed on a maxilla, the second arch bar including a second longitudinal axis, a plurality of elongated second slots extending laterally along the second longitudinal axis and defined by a plurality of second lateral supports and a plurality of integrally formed second hooks, each of the second hooks being free of holes;
- a plurality of first bone screws each including a first threaded shaft, the first bone screws extending through the first slots such that the first threaded shafts extend into the mandible;
- and
- a plurality of second bone screws each including a second threaded shaft, the second bone screws extending through the second slots such that the second threaded shafts extend into the maxilla.
A medical apparatus comprising:
- a first curved arch bar configured to be placed on a mandible, the first arch bar including a first longitudinal axis, two elongated first slots laterally extending along the first longitudinal axis and defined by a plurality of first lateral supports and two integrally formed first hooks each being free of holes;
- a second curved arch bar configured to be placed on a maxilla, the second arch bar including a second longitudinal axis, two elongated second slots laterally extending along the second longitudinal axis and defined by a plurality of second lateral supports and two integrally formed second hooks being free of holes;
- two first bone screws configured to extend through a different of the first slots and into the mandible;
- two second bone screws configured to extend through a different of the second slots and into the maxilla;
- a first wire connecting one of the first hooks to one of the second hooks;
- and
- a second wire connecting another of the first hooks to another of the second hooks.
