A recent study published in Scientific Reports suggests that two-screw osteosynthesis may be biomechanically superior to single-screw osteosynthesis for type II odontoid fractures. The research, conducted at the University of Göttingen, utilized 18 human functional spinal units to analyze the impact of different fixation methods on the stability of the spine. Computed tomography scans were utilized to assess bone mineral density, and artificial fractures were created to simulate real-world conditions. The study found that the use of two screws provided greater resistance to rotational forces compared to a single screw, potentially offering improved outcomes for patients with this type of fracture. Further research and clinical trials may be necessary to validate these findings and explore their implications for patient care.
