Abstract: An improved guide system and method permits a user to insert a fixation device, such as a pin, screw, wire and/or the like, into a bone portion. A guide system may comprise a handle portion and a body portion, wherein the body portion comprises one or more channels configured to facilitate placement and insertion of a fixation device.

Abstract: An improved bone screw is disclosed which includes a shaft with distal portion having a threaded surface thereon, a sleeve having an opening which receives the shaft such that the shaft is able to move within the sleeve without moving the sleeve. A compressive device may be incorporated between the sleeve and the proximal portion of the shaft such that the compressive device forces the shaft and sleeve towards at least a portion each other, thereby maintaining the compressive load at the union of the fracture. As additional compression is exerted on the load from weight bearing, the force may be reduced, but the head of the sleeve is still substantially maintained against the lateral cortex.

Abstract: A system and method for facilitating the fixation of bone fractures is disclosed. The anchor component includes a tip, cutting threads and mating threads which are inserted into the far cortex of the bone. A wire extends from the anchor component and exits from the near cortex. A cap device includes a tension spring, a ratcheting mechanism, a lever clutch, and/or at least one wedge, wherein the tension spring, ratcheting mechanism, lever clutch, and/or at least one wedge is configured to assert friction against the wire when the cap is translated in one direction, but minimal friction against the wire when the cap is translated in the opposite direction. The cap is threaded over the wire such that the cap is restricted from backwards movement.

Abstract: A system and method for facilitating the fixation of bone fractures is disclosed. The head component includes a tip, cutting threads and mating threads which are inserted into the far cortex of the bone. A wire extends from the head component and exits from the near cortex. A cap device includes a tension spring, wherein the tension spring is configured to assert friction against the wire when the cap is translated in one direction, but minimal friction against the wire when the cap is translated in the opposite direction. The cap is threaded over the wire such that the cap is restricted from backwards movement. Tension is then applied to the wire while the cap is tightened against or within the bone surface to apply an appropriate amount of pressure between the surfaces of the fracture. The excess wire beyond the cap can then be removed.
