Abstract:
Objective To report a new designed technique of CT-guided percutaneous puncture for atlantoaxial lateral mass arthrodesis with bone graft and discuss its clinical usefulness and effect. Methods From March 1999 to March 2001, on the base of anatomical investigation of 56 adult cadaversatlas and axis bone specimens, 9 cases with instability of atlantoaxial were treated after reduction by traction, 4 of 9 cases underwent Halo-Vest immobilization, and the other 5 cases underwent transarticular screw fixation through C2 vertebral body for atlantoaxial instability. Of all nine cases, the articular cartilage and capsule of post lateral part of atlantoaxial joints were removed by using home made surgical instruments under CT guidance. Iliac cancellous bones obtained by puncture were implanted into the joint space. Results All cases were followed up from 2 to 17 months (average 12.7 months) and 8 cases more than 6 months. Generally, at the third to fourth month after operation, CT scan showed bony union of the grafted bone and the excessive extension and flexion X-ray films showed stable movement of the atlantoaxial joints, and then the Halo-Vest stock were removed. Conclusion This technique has obvious advantages of less trauma and hemorrhage, high union rate, easy, safe and efficiencies.
