摘要:
Disclosed are 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 (110) with threads (114) to effect engagement of the device and to act as an insertion - stop for the device, as well as a helical portion (120) to allow for adequate purchase into bone. The helical portion engages the bone over a relatively large surface area relative to the size of the entry point. The helical portion may resemble, for example, a cork screw or a coiled spring. The device offers both flexibility (to make angled insertion achievable) while still retaining enough helical - directional rigidity to achieve the desired implantation and fixation. A guide (300) with a helically- grooved encasement (310) to bend the device as it advances is also disclosed.
