Abstract:
[Objective]To discuss surgical approaches,results and complications of ossification of posterior longitudinal ligament(OPLL)of cervical spine.[Method]The clinic data of 48 patients from 2000 with cervical OPLL were reviewed and analyzed.Eighteen of them were decompressed from an anterior approach and 30 from a posterior approach.The improvement rate according to JOA scoring system were evaluated,some relevant imaging examination data including X-rays,CT and MRI were also measured,which were taken preand post-operatively.Surgical complications were also recorded.[Result]Of 48 patients,23 had cervical stenosis,the mean occupancy rate was 41.4%,and 19 had the abnormal signal in spinal cord.The mean postoperative improvement rate was 68.3% in patients treated by anterior decompression and 51.3% in those treated by posterior decompression.There were 2 patients with dural tear,5 with segmental nerve root palsy and 2 with hematoma after operation.[Conclusion]Suitable operation methods should be chosen according to the location,extent and occupancy ratio of OPLL,which is important for avoiding complications and improving surgical results.
