Abstract:
Objective To evaluate the application of cervical lateral mass plate fixation in the treatment of fracture and dislocation of lower cervical spine. Methods From February 2001 to June 2003, 21 cases of lower cervical spine injury were treated by cervical lateral mass plating fixation, received spinal decompression and reduction according to the types of fracture and dislocation. A cervical lateral mass plate was applied in each lateral mass. The screw prick point was defined at 1-2 mm inner and lower to the mass center. The sagital angle, horizontal angle of internal fixation screw were 45 degrees and 25-30 degree respectively. Results The follow up ranged from nine months to two years and nine months (mean 13 months). All cases were encouraged to sit up, wearing soft collar 4-7 days after the surgery. The mean off-bed time of those cases without spinal cord injuries less than Frankel C grade were seven days (4-14 days) after operation. All cases obtained solid bony fusion 4-6 months postoperatively. Sixteen cases with spinal cord injury improved for one grade according to American Spinal Injury Association. Three cases with nerve root injury obtained complete recovery after operation. There was no severe complication such as vertebral artery nerve root or spinal cord injuries or aggravation of spinal cord injury. One case had uneven reduction and two suffered screw loosening. Conclusion Cervical lateral mass plate fixation is an efficient and reliable technique for segmental posterior fixation, for it has the advantages of wide indication, relatively simple and safe operating as well as strong stability.
