Abstract:
Objective To investigate the results of early decompression and internal fixation for lower cervical vertebral degenerative instability. Methods Eighty-two patients of low cervical vertebral degenerative instability were reviewed. The patients comprised of 51 males and 31 females, with an average age of 54.3 years. There were 13 patients with neck and shoulder pain, 28 with cervical spondylotic radiculopathy (CSR), 25 with cervical spondylotic myelopathy (CSM), 16 with combined CSR and CSM. Magnetic resonance imaging(MRI) showed that the cervical spinal cords were compressed. All patients had cervical vertebral angular displacement (AD) exceeding 10? or horizontal displacement(HD) surpassing 3 mm at the same level on hyperflexion/hyperextension X-ray films. According to the course of cervical degenerative instability and Kirkaldy-Willis criterion, all patients were diagnosed as cervical vertebral degenerative instability, and recieved anterior decompression, bone grafting and internal fixation. Results All the patients were followed for 9 to 30 months (average 15.4 months). All fused segments achieved bony union. 1) JOA score of 25 cases with CSM and 16 cases with CSR and CSM was 9.52?1.93 before operation and 14.74?3.10 post operation respectively. There was significant statistical difference (P
