Disclosed are several embodiments directed to a flexible fixation device and method to provide adequate purchase into bone at angles that are awkward for properly engaging inflexible and rigid screws. In one instance, the fixation device is comprised of a head to effect engagement of the device and to acts as an insertion-stop for the device, as well as a helical portion of a suitable cross-sectional geometry to allow for adequate purchase into bone. The helical portion provides fixation as the helical form engages the bone over a relatively large surface area relative to the size of the entry point. The helical portion may be variously configured to resemble, for example, a cork screw, a coiled spring, and so forth. Most variations offer both flexibility (to make angled insertion achievable) while still retaining enough helical-directional rigidity to achieve the desired implantation and fixation. |
