Atlantoaxial instability is a serious condition leading to symptoms like walking difficulties and limited neck mobility, for which atlantal lateral mass screw fixation is a recognized surgical method.
The study analyzed 158 dried human C1 vertebrae to measure important dimensions related to screw placement using precise digital calipers.
Findings include specific measurements for the screw entry zone and distances related to the vertebral artery groove, providing valuable data for surgeons to improve the accuracy of their procedures.
