RESUMO

Spinal biomechanics, especially the range of spine motion,has close connection with spinal surgery. The change of the range of motion (ROM) is an important indicator of diseases and injuries of spine, and the essential evaluating standards of effect of surgeries and therapies to spine. The analysis of ROM can be dated to the time of the invention of X-ray and even that before it. With the development of science and technology as well as the optimization of various types of calculation methods, diverse measuring methods have emerged, from imaging methods to non-imaging methods, from two-dimensional to three-dimensional, from measuring directly on the X-ray films to calculating automatically by computer. Analysis of ROM has made great progress, but there are some older methods cannot meet the needs of the times and disappear, some classical methods such as X-ray still have vitality. Combining different methods, three dimensions and more vivo spine research are the trend of analysis of ROM. And more and more researchers began to focus on vivo spine research. In this paper, the advantages and disadvantages of the methods utilized recently are presented through viewing recent literatures, providing reference and help for the movement analysis of spine.

RESUMO

<p><b>OBJECTIVE</b>To explore the clinical effects of total vertebral column resection combined with anterior mesh cage support in treating severe congenital kyphoscoliosis.</p><p><b>METHODS</b>From April 2008 to April 2012,21 patients with severe congenital kyphoscoliosis were treated with total vertebral column resection and internal fixation through posterior approach combined with anterior mesh cage support. There were 8 males and 13 females with an average age of 19.4 years old (ranged from 10 to 35). And 6 cases were thoracic segments deformity,13 cases were thoracolumbar segments and 2 cases were lumbar segments, of them, 2 cases were accompanied with Chairs deformity, 6 cases with diastematomyelia, 4 cases with syringomyelia,and 1 case with neurofibromatosis. According to the Frankel grade system, 3 cases were grade C, 5 cases grade D and 13 cases grade E. Blood loss, operative time, and perioperative complications were recorded. Coronal and sagittal Cobb angle, apical vertebral offset distance, sagittal offset, the relative height of shoulders, razor back deformities were measured and analyzed before and after operation.</p><p><b>RESULTS</b>The average operative time was 5.2 h (3.5 to 6.5 h) and blood loss was 2,500 ml (1,400 to 4,900 ml). The 2nd day after operation, apical vertebral offset distance, sagittal offset, the relative height of shoulders, razor back deformities had obviously improved than preoperative (P < 0.05). There was no significant difference in above items between postoperative on the 2nd day and final follow-up (P > 0.05). The corrective rate of kyphosis and scoliosis were (60.97 +/- 6.30)% and (62.24 +/- 5.82)%, respectively. On the first day after surgery,2 cases of Frankel grade E aggravated to grade D, and obtained recovery at 2 week after conservative treatment. And 1 case palinesthesia later,grade D aggravated to grade C and obtained recovery after revision surgery in time. One case complicated with permanent blindness of left eye, 1 case occurred injury of pleura and 2 cases had cerebrospinal fluid leak during operation. All patients were followed up from 9 to 31 months with an av- erage of 18.6 months. At final follow-up,all patients obtained bone union, Frankel grade D in 4 cases and grade E in 17 cases, no correction loss and internal fixation loosening was found.</p><p><b>CONCLUSION</b>Total vertebral column resection combined with anterior mesh cage support can effectively correct kyphosis and scoliosis in severe congenital kyphoscoliosis and can avoid injury of spine cord by spinal crispation, but intraoperative position and neurologic complications should still be considered.</p>
