Abstract
An embodiment of a body bead for a bone-fracture fixation device, such as a rodscrew, includes at least one pocket and at least one tab. Each of the at least one pocket is configured to engage a respective one of at least one tab of an adjacent body bead and to withstand, without being significantly deformed, a torque of at least three N·m while rotating with the adjacent body bead. And each of the at least one tab is configured to engage a respective one of at least one pocket of another adjacent body bead and to withstand, without being significantly deformed, a torque of at least three N·m while rotating with the other adjacent body bead.

-54. (canceled)
A fixation device, comprising:
- an elongate body comprising a plurality of interconnected beads, wherein at least some of the beads comprise:
- a base having a cylindrical shape and extending longitudinally between first and second ends, the base having a base diameter;
- at least one tab each protruding from the first end in a direction away from the base, configured to engage a respective one of at least one pocket of an adjacent body bead, and having a respective tab thickness at least one fourth the base width, wherein each of the at least one tab is positioned along a diameter of the base such that the respective tab thickness is in approximately a same dimension as the diameter;
- and
- at least one pocket each formed in the base at the second end and configured to engage a respective one of at least one tab of another adjacent body bead.
A fixation device, comprising:
- an elongate body comprising a plurality of interconnected beads, wherein at least some of the beads comprise:
- a base having a cylindrical shape, first and second ends, and a base diameter;
- at least one tab each protruding from the first end, configured to be received within a respective one of at least one pocket of an adjacent body bead, and having a respective tab thickness at least one fourth the base width,
- at least one pocket each formed in the base at the second end and configured to receive a respective one of at least one tab of another adjacent body bead;
- wherein the base has a base height from the second end to the first end;
- and
- wherein each of the at least one pocket has a height from the second end that is in an approximate range of three tenths the base height to nine tenths the base height.
A fixation device, comprising:
- an elongate body comprising a plurality of interconnected beads, wherein at least some of the beads comprise:
- a base extending longitudinally between first and second ends, a base width, and a base height from the second end to the first end;
- at least one tab each protruding from the first end in a direction away from the base, configured to engage a respective one of at least one pocket of an adjacent body bead, and having a respective tab thickness at least one fourth the base width, wherein each of the at least one tab protrudes a tab height that is in an approximate range of one fourth the base height to the base height;
- and
- at least one pocket each formed in the base at the second end and configured to engage a respective one of at least one tab of another adjacent body bead. (New) The device of claim 74, wherein the elongate body is configured to be implanted in a bone of a patient.
A fixation device, comprising:
- an elongate body comprising a plurality of interconnected beads, wherein at least some of the beads comprise:
- a base having a cylindrical shape and extending longitudinally between first and second ends, the base having a base diameter;
- at least one tab each protruding from the first end in a direction away from the base, configured to engage a respective one of at least one pocket of an adjacent body bead, and having a respective tab thickness at least one fourth the base width,
- at least one pocket each formed in the base at the second end and configured to engage a respective one of at least one tab of another adjacent body bead;
- wherein each of the at least one pocket includes a respective pocket neck having a pocket-neck width;
- and
- a respective pocket head adjacent to the respective pocket neck and having a width that is approximately twice the pocket-neck width.
