Clinical effect observation of transpedicular vertebral osteotomy spine shortening in treating spinal kyphosis complicated with spinal cord nerve dysfunction / 局解手术学杂志

ABSTRACT

Objective To study the clinical effect of transpedicular vertebral osteotomy spine shortening in treating spinal kyphosis com-plicated with spinal cord nerve dysfunction. Methods A total of 80 patients with spinal kyphosis complicated with spinal cord nerve dys-function in our hospital from May 2013 to June 2014 were enrolled and randomly divided into observation group(n=40) and control group (n=40). The observation group received transpedicular vertebral osteotomy,and the control group received lamina and facet osteotomy. The situation of surgery,vertebral healing and spinal cord function condition,treatment effect between two groups were compared. Results The operation time and postoperative ambulation time of observation group were shorter than those of control group [(76. 52 ± 9. 1) vs (113. 46 ± 13. 44) min,(3. 28 ± 0. 43) vs (5. 67 ± 0. 68) d]. The postoperative bleeding volume,postoperative drainage volume of observation group were less than those of control group [(36. 14 ± 4. 28) vs (55. 23 ± 7. 15) mL,(17. 92 ± 2. 12) vs (29. 64 ± 4. 28) mL]. The Cobb angle and residual urine volume,initial and strong urinary bladder capacity,maximum urinary output of observation group were significantly less than those of control group [(6. 12 ± 0. 68) vs(9. 78 ± 1. 21) mL,(241. 45 ± 28. 56) vs(335. 54 ± 36. 86) mL,(456. 56 ± 51. 78) vs (586. 35 ± 63. 12) mL,(63. 78 ± 7. 24) vs (96. 32 ± 10. 22) mL]. The intervertebral height of observation group was higher than that of control group [(12. 62 ± 2. 81) vs (8. 41 ± 1. 32) mm]. The excellent rate of observation group was significantly higher than that of control group(97. 50%vs 82. 50%). Conclusion Transpedicular vertebral osteotomy spine shortening is helpful to reduce operation wound, pro-mote postoperative recovery,correct kyphotic deformity and improve neurological functionin,improve therapeutic effect.
