BACKGROUND:Anterior cervical discectomy and intervertebral disc replacement have been extensively used in treatment of cervical degenerative disease. Its short-term therapeutic effects are encouraging, but it lacks of long-term and comprehensive evaluation.
OBJECTIVE:To observe the folow-up results of a group of cases of anterior cervical discectomy and Mobi-C intervertebral disc replacement for more than 5 years.
METHODS:A total of 25 cases of cervical spondylosis were treated in the 309 Hospital of Chinese PLA from January to September 2009. 19 of them were folowed up. Al patients received anterior cervical discectomy and Mobi-C intervertebral disc replacement. Twenty-three Mobi-C intervertebral disc prostheses were implanted. The range of motion was measured using lateral X-ray films during extension and flexion. Ectopic ossification was assessed by McAfee method. According to the cervical vertebra MRI images, the degeneration of adjacent segments was determined using Pearce classification. NDI score was used to evaluate the function of cervical spine. Pain improvement was evaluated using visual analogue scale score.
RESULTS AND CONCLUSION: A total of 19 patients were folowed up for 59-65 months, averagely 62 months. No significant difference in range of motion was detected before surgery and during final folow-up (P > 0.05). Ectopic ossification in two cases and the degeneration of adjacent segments in one case were found during final folow-up. No prosthesis loosening or displacement appeared. Visual analogue scale score and NDI score were significantly lower during final folow-up compared with that before surgery (P < 0.05). These results indicate that under the premise of reasonable choice of indications, the therapeutic effect of Mobi-C intervertebral disc replacement for degenerative cervical spondylosis was satisfactory in five-year folow-up. The range of motion was good, and the incidences of ectopic ossification and the degeneration of adjacent segments were low.

Objective To evaluate the surgical outcomes in patients with lumbar disorder treated with enlargement of the spinal canal through spinous process osteotomy. Methods Posterior central incision was used for unilateral exposure of lamina. Osteotomy was done at the base of the spinous process; complete exposure of the lamina was done by retracting the interspinous and supraspinous ligaments. Ligament flaven was resected at the superior and inferior margin of the lamina. Undermining enlargment of the central spinal canal and the neural canal were then carried out; in some cases the intervertebral disc was resected. Thirty seven patients suffered from lumbar spinal stenosis were treated with the above mentioned procedure; among them decompression of a single segment was done in 24 cases, in two segments in 13 cases. Postoperatively, Oswestry evaluation score and imaging observation were carried out. Results Thirty four cases had follow up for one year and the excellent and good results was seen in 82.4%; 27 cases had follow up of 3 years, the rate of excellent and good results was 81.5%. Both sagittal and transverse diameter of lumbar vertebrae canal were increased notably in postoperative CT scanning. 87% of osteotomized spinous processes had bony fusion. Conclusion Spinal canal plasty by spinous process osteotomy for patients with lumbar disorders affords easy performing procedure with less complications and satisfactory surgical results.

From July 1997 to March 2000, internal fixation of posterior transpedicular screw system and posterolateral autograft bone graft fusion procedures were used in 25 patients suffering from Pott's paraplegia in our department. 17 of them were involved in a longitudinal study and followed up for a mean of 2(1 5~4)years postoperatively. The beginning of neurologic recovery was during the first 2 to 3 weeks postoperatively in 16 patients. 9 were completely recovered,7 were partly recovered 6 months postoperatively. At final follow up, 2 of the 7 patients were completely recovered, 5 had significant improvement of one grade(2 patients) or two (3 patients) according to ASIA Grades. It is concluded that internal fixation of posterior transpedicular screw system and posterolateral autograft bone graft fusion procedures were found to be helpful in strengthening the stability of the spine in spinal tuberculosis, providing successfu recovery of paraplegia and preventing the recurrence of paraplegia.

Objective To investigate the radiographic characteristics of degenerative lumbar scoliosis (DLS) and its relationship to osteoporosis. Methods 229 cases (83 males, 146 females) of DLS from January 1998 to June 2005 were reviewed. The mean age was 56.8 years (ranged from 40 to 74 years). The Cobb angle and vertebral stability in coronal plane were measured in anteroposterior radiographs and the changes of lordosis in sagittal plane were observed in lateral radiographs. The bone mineral density(BMD) and T-Score of lumbar spine (L2-L4) were measured using Dual Energy X-ray Absorptiometry. Results The mean Cobb angle is 9.45??4.79?, 151 cases(66%) with the angle less than 10?, 60 cases (26%) with 10?-20?, and 18 cases (8%) with more than 20?. Right side scoliosis were found in 52% (120 cases), left side in 48% (109 cases). 159 cases (69%) companied with gradeⅠ(Nash-Moe) vertebra rotation, 54 cases (24%) with grade Ⅱ. And the vertebra rotation was most evident on scoliosis apex. There were 20 cases (9%) with more than 4 mm lateral translation between the lumbar vertebrae which were usually the apex vertebrae with the most degenerative changes. The physical lordosis decreased in most cases in which 16 cases (7%) developed lumbar or thoracolumbar kyphosis. And the kyphosis degree was not relevant to scoliosis Cobb angle. The mean T-Score of BMD measurement was -1.88?0.17, which was -1.49?0.14, -2.56?0.24, -2.89?0.50 for the groups of with Cobb angle 20? respectively. There were 153 cases (67%) with T10?), and 98 cases (43%) with T

Objective To investigate the clinical outcomes of interbody fusion with transpedicular screw fixation in the reoperation for lumbar spinal instability secondary to lumbar discectomy.Methods From May 1997 to Aug 2002, 23 patients underwent reoperation with posterior lumbar spinal decompression, removal of residual disc, transpedicular screw instrumentation and interbody fusion because of lumbar spinal instability after previous lumbar discectomy. There were 14 males and 9 females. The age of patients ranged from 28 to 64 years with an average age of 48.5 years. The time between the onset of the symptoms and the diagnosis was 18 months on average (range, 6 months to 36 years). The mean interval between the primary and revision surgery was 68 months (range, 24 months to 10 years). Lumbar discectomy had been performed in all patients as the primary surgery. All patients were evaluated by the conventional radiography, and CT or MRI if necessary. The low back pain was predominant in 8, and associated with radicular leg pain in 15. The instability of one segment was found in 17, and two segments in 6. The average follow-up was 3.6 years (range, 1 to 6.4 years). Results The lateral, AP, flexion and extension X-ray films were taken at 1, 3, 6 months and 1 year to evaluate the fusion, sliding between two vertebral bodies and internal fixation, and McGill pain questionnaire was adopted to determine the satisfaction of the patients. The intraoperative blood loss ranged from 550 to 800 ml (mean, 650 ml), and the total operative time ranged from 120 to 210 min (mean, 180 min). Based on Oswestry low back pain and disability scores, the clinical successful rate was 86.9%. The rate of patient satisfaction was 82.6%. 20 patients showed radiographic bony fusion. Pedicle screw breakage and loosening were found in 3 out of the 102 screws. 5 patients had nerve root irritation and recovered within 2 to 3 weeks. 5 patients had dural laceration. Bony nonunion was found in 3 patients. Conclusion Transpedicular screw instrumentation and interbody fusion is proved helpful in management of spinal instability secondary to decompression surgery, providing successful interbody fusion and restoration of the intervertebral stability.
