Traction pin assemblies, components, systems, and methods

A traction pin assembly, the traction pin assembly comprising:

• a traction pin including a shaft that extends between an end of the traction pin and a tip of the traction pin;
• the tip of the traction pin having a diamond shape;
• an adapter through which a first portion of the shaft of the traction pin extends, the adapter to couple with a driver to axially retain the traction pin relative to the driver;
• and
• a guide coupled with the traction pin between the adapter and the tip of the traction pin, the guide defining a passage through which a second portion of the shaft of the traction pin extends and comprising a surface to grip the guide, the surface having a larger surface area than a surface of the second portion of the shaft, the guide removably coupled with the traction pin while the adapter remains coupled with the traction pin and the driver.

A method, comprising:

• providing an apparatus, including:
• a traction pin including a shaft that extends between an end of the traction pin and a tip of the traction pin;
• and
• an adapter through which a first portion of the shaft of the traction pin extends, the adapter to couple with a driver to axially retain the traction pin relative to the driver;
• coupling a guide with the traction pin between the adapter and the tip of the traction pin, the guide including a first half and a second half pivotably coupled together with a hinge, wherein the hinge separates the guide into a first portion of the guide on a first side of the hinge and a second portion of the guide on a second side of the hinge, and wherein at least a portion of each of the first half and the second half of the guide include at least one tab to limit an amount by which the first half and the second half of the guide can pivot towards each other;
• and
• inserting the traction pin into tissue.

A traction pin, comprising:

• a first portion of the traction pin to couple with a driver, the driver to rotate the traction pin;
• a tip;
• a shaft;
• a first end to be received by the driver to couple the first portion of the traction pin with the driver;
• a second end, toward the shaft, to engage an adapter, the adapter to slidably dispose on the shaft between the tip and the first portion of the traction pin, and the adapter to couple with the driver to engage the second end and to retain the first portion of the traction pin in the driver;
• and
• the shaft including a guide to couple with the shaft between the adapter and the tip, the guide to define a passage through which a portion of the shaft extends and including a surface to grip the guide, the surface having a larger surface area than a surface of the portion of the shaft, the guide to removably couple with the shaft while the adapter remains coupled with the shaft and the driver.
