[Abstract]:Objective to investigate the feasibility of the application of computer aided nailing technique in the accurate placement of atlantoaxial screws. Methods a retrospective analysis of 51 cases of atlantoaxial instability in the two ward of Henan Province People's Hospital from January 2014 to January 2016 was performed in two cases of atlantoaxial instability, including 28 males, 23 females, age, and age. 54 years old, with an average age of 42.7 years. Before operation, 27 cases of nail parameter simulation were designed by BOHOLO surgical simulator, which were defined as experimental group, including old odontoid fracture in 7 cases, congenital odontoid dysplasia in 12 cases, and fresh odontoid fracture (Anderson IIC type) in 8 cases. The preoperative planning of the BOHOLO surgery simulator was not used for operation. A total of 24 cases were defined as the control group, including 6 old odontoid fractures, 10 congenital odontoid dysplasia and 8 fresh odontoid fractures (Anderson IIC type). The CT data of the experimental group were introduced into the BOHOLO software to design the best nail path of the atlas side block and define the parameters (the distance to the nailed point to the lateral margin of the vertebral canal, the distance L1 of the pedicle edge, to the atlas positive. " The median sagittal distance was L2, the length of the nail path was D, the horizontal angle TSA of the nail path, the sagittal angle SSA), and the parameters of the actual nail path after the operation were measured by BOHOLO software and compared with the preoperative planning parameters. At the same time, the operation time (min) and the amount of bleeding (ML) were compared between the two groups, and the postoperative CT of the two groups of patients was transferred to the CT axis and the crown by the BOHOLO multiplane recombination imaging. The position of two groups of screws was observed, and a reliable area of the side block was divided on the axial position: the projection area of the upper articular surface in the side block, the screw fixation and the most reliable strength in this area, the unreliable nail strength outside the reliable area and the risk of injury to the spinal cord or the vertebral artery. JOA score, VAS score and fusion rate were used to evaluate the curative effect. Results all patients had no vertebral artery and nerve injury during the operation, and all the patients were followed up for a period of 7~13 months, mean 9 months, and 6 months after the operation, all of them were fused without screw loosening, displacement and fracture. The baseline data of the two groups of patients, There were no statistical differences in the composition of the medical records. In the experimental group, 54 screws were placed in the lateral mass of the atlas, which were all located in the reliable area, accounting for 100%. The optimum nail path parameters L1 (left 5 + 0.92mm, right 5.19 + 0.83mM), L2 (left 19.22 + 1.19mm, right 18.96 1.09mm), D (left 20.67 + 1.62mm, right 20.26 + 1.53mm), TSA (left 12.11 + 1.40 degrees, right 11.93 + 1.4) 7 degrees), SSA (left 19.82 + 1.33 degrees, right 19.56 + 1.31 degrees), actual nail channel parameters L1 '(left 4.74 + 0.71mm, right 5.11 + 0.97mm), L2' (left 18.96 + 1.16mm, right 19.04 + 1.06mm), D '(left 20.48 + 1.55mm, right 20.48 + 1.81mm), TSA' (left 12.19 + 1.57 degrees, right left-hand degrees), SSA ' There was no statistically significant difference between the planning and the actual parameters (P0.05). 48 screws were inserted in the control group, of which 42 screws were located in the reliable area, accounting for 87.5%, and the difference between the experimental group (P0.05) and the two groups (107.22 + 12.96min, 116.88 + 16.73min), respectively (403.70 + 101.61ml, 484.58 + 138.00ml), respectively. There were statistical significance (P0.05); the preoperative JOA scores in the two groups were (6.89 + 1.65,7.33 + 1.58), VAS scores were (3.67 + 0.73,3.46 + 0.59), and JOA scores were (13.15 + 2.54,12.58 + 2.62) at the last follow-up, and VAS scores were (1.70 + 0.61,1.54 + 0.66) respectively. The differences in the groups were significant (P0.05), but there was no statistical difference between the groups. Study significance (P0.05). Conclusion computer aided simulation nail placement can assist in the accurate placement of nail, and help to improve the accuracy of nail placement, reduce intraoperative bleeding and shorten the operation time.
