Decompression And Fusion With Titanium Mesh And Bone Graft And Internal Fixation In The Treatment Of Double Segment Spondylotic Cervical Myelopathy In Anterior Cervical Corpectomy And Long Term Follow--up

Objective: Analysis and review of anterior cervical corpectomy decompression and fusion with titanium mesh fixationand the long-term treatment of double segment cervical myelopathyMethods: Reviewing and analyzing from January 2008 to December 2011,the1 st affiliated hospital,use the Anterior cervical corpectomy decompression and fusion graft fixationto treat 43 patients who have double segment cervical myelopathy.In these 43 cases, male 21 cases, female 22 cases, age from 39 to 74 years old, the average(56.3±12.7), preoperative duration of 3 ~ 36 months, average 36 months, their vertebral bodies are C3-5 segments in 11 cases, C4-6 segments in 16 cases, 16 cases of C5-7 segments. All the 43 patients have been completed the surveies of iconography and clinical, before and after their operations. According to the standard of Japanese Orthopedic Assoeiation JOA and changes in height between the cervical spinal bend and taper,doctors can evaluate the recoveries of physical dysfunction and the relief situations of nerve compression.Results: All the patients have completed the follow- up visits. The average follow-up visits are 2.9±1.23 years. All the patients recover well without the loose and breakage of fixed position. After the last operation and the follow-up visit, patients’ symptoms were alleviated. All patients preoperative and postoperative JOA score before operation is 8.5 + 1.4 and postoperative JOA score is 12.5 + 1.3 points. The last JOA score is 14.5 + 1.3.The difference of JOA score before and after operation has statistically significant(P < 0.05). The difference of the last follow-up visit and preoperative JOA score has statistically significant(P < 0.05). The neural improvement rate of excellent and good rate is 83.72%. The cervical spinal curvatureof patients have recovered obviously after operation which contrast the standard before operation. The difference of cervical spinal curvaturebefore and after operation have statistical significance(P < 0.05). There is statistical significance at the time of the latest follow-up and before operation ‘s difference of cervical spinal curvature(P < 0.05). The patients with cervical intervertebral height is better than that of pre operation.Conclusion: The retrospective study of anterior cervical corpectomy decompression and fusion bone graft and internal fixation double cervical myelopathy can indicate thatnterior cervical corpectomy decompression and fusion with titanium mesh fixationand can significantly improve the neuropathic functions of double segment cervical myelopathy, Stabilize the cervical spine,the recovery of cervical spinal curvature and cervical intervertebral height. The long-term curative effect is obvious. All the results are proved by the change of cervical spinal curvature and cervical intervertebral height and the low back pain operation criteria of the preoperative, postoperative, at the time of the latest follow-up visit of low back pain score(Japanese Orthopedic standard operation Assoeiation JOA).
