| 发明名称 | Pedicle screw with reverse spiral cut and methods thereof | ||
| 摘要 | A pedicle screw with reverse spiral cut that allows for increased loading on a bone and increased osteointegration through automatic and self-managed expansion after the bone screw is inserted into the bone. The bone screw may be a fixation device comprising an elongated body having proximal and distal ends, said elongated body including an outer surface adapted to penetrate and anchor within a bone, and a head affixed to the distal end of the elongated body and adapted to receive a drive component, wherein the outer surface of the elongated body comprises threads extending from the outer surface in a first direction, and further wherein at least a portion of the outer surface of the elongated body comprises a reverse spiral cut into the outer surface in a second direction. | ||
