Abstract
A flexible spinal fixation device and a rod thereof are provided. The flexible spinal fixation device includes at least two bone screws and a rod. The rod is fixedly coupled to the bone screws, and the bone screws are implanted into a patient's vertebrae. The rod has a flexible part and is thereby rendered flexible. After the flexible spinal fixation device is implanted into the patient's spine, the patient's spine can stoop as in a healthy condition. Moreover, vertebral stress around an injured vertebra and force between the bone screws and the rod can both be reduced. The flexible spinal fixation device also prevents premature vertebral aging and has an extended service life.
