ABSTRACT
[Objective]To analyze the correlation between disk degeneration and development of isthmic spondylolisthesis in adults.[Method]Totally 156 patients who had spoondvlolvsis and spondylolisthesis were follow-up.There were 86 males and 70 females.All patients were made radiographs for lumbar discomfort or low back pain.Spondylolysis and spondylolisthesis were discovered.According to Meyerding slip degree;68 cases were spondylolysis,88 cases were spondylolisthesis in degree Ⅰ.All patients were under conservative treatment and observed the development of the disease.According to Boxall defined the development of spondylolisthesis.There were 40 patients with development of spondylolisthesis and aggravation of dies degeneration.24 males,16 females.[Result]All the patients were followed-up for 3~9 years,with an average of 6.3 years.Lumbar vertebra slippage increased about 11%~30%(average 18.5%),the height of intervertebral disk decreased about 45%~90%(average 72%)in the level of spondylolysis.x2 test was used for statistical treatment,There was a significant positive correlation between development of isthmic spondylolisthesis in adults and aggravation of disk degeneration.[Conclusion]There are development in adults of spondylolysis and spondylolisthesis,may be correlated to the disc degeneration.
ABSTRACT
[Objective]To analyse the significance of degenerative instability in pathogensis of cervical syndrome.[Method]A total of 216 patients who underwent neck and shoulder pain and/or cervical spondylotic radiculopathy(CSR)were followed-up.There were 143 males and 73 females,aged from 29 to 41,with the average of 37.8.Number of patients with neck and shoulder pain were 173,with cervical spondylotic radiculopathy were 28,with neck and shoulder and CSR were 15.According to cervical degenerative instable radiology standard,instable group included 82 cases,stable group included 134 cases.All patients were treated by physiotherapy and/or local caging therapy.[Result]All the patients were followed-up for 2～7 years,with an average of 4.3 years.In the instable group,4 patients were found osteophyma at the instable vertebra,3 were intervertebral disk hernia,6 were intervertebral disk hernia and osteophyma,3 were T_2 high intensive sign(T_2 HIS)in spinal cord at the instable vertebra.In the stable group,2 were found intervertebral disk hernia at C_(4~5),2 were found osteophyma at C_5 vertebra.The incidence of cervical syndrome was 19.51% in instable group and 2.99% in stable group.There was significant statistical difference(P
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
