摘 要：Background:A rare case of atlantoaxial lateral mass joint interlocking secondary to traumatic posterolateral C1/C2 complete dislocation associated with type II odontoid fracture is reported,and the impact of atlantoaxial joint interlocking on fracture reduction is *** presentation:This case is of a 72-year-old man presented with traumatic atlantoaxial lateral mass joint interlocking without spinal cord signal change,which is confirmed by radiographs and 3 D reconstruction digital *** internal fixation was performed after closed reduction with skull traction was not ***,after many surgical reset failed due to the interlocking of lateral mass joints,we tried to compress the posterior parts of the atlantal and axial screws,the reduction was achieved ***,odontoid bone union and C1/C2 posterior bone graft fusion were obtained at the 12-month ***:To our knowledge,the atlantoaxial lateral mass interlocking is a relatively stable biomechanical *** is like a double-edged sword for the reduction of atlantoaxial dislocation and the secondary spinal cord injury.
