Abstract
Objective To explore the clinical effect of lumbar fusion via vertebra-side muscle clearance and tradition-al posterior approach. Methods The 184 patients who need surgery were divided into two groups randomly. All the patients were received lumbar fusion via vertebra-side muscle clearance approach (91 cases, the experimental group) and traditional posterior approach (93 cases, the control group). Some parameters like surgical time, perioperative blood volume, postoperative drainage, bed time, changes of creatine kinase ( CK) content, satisfaction,VAS were observed by clinicians. Results All patients received follow-up within 12~38 months. Average surgical time and bed time in experimental group was (114. 8 ± 13. 4) min and (2. 47 ± 0. 48) d, which was lower than control group (134. 9 ± 24. 2) min and (4. 41 ± 2. 28) d, P<0. 05. For perioperative blood volume and drainage, the figure in experimental group (146. 2 ± 48. 4) ml and (97. 3 ± 17. 5)ml, which was lower than control group (211. 8 ± 52. 4) ml and (147. 2 ± 45. 5)ml,P<0. 05. VAS in the postoperative and at last follow-up were 2. 06 ± 0. 43 and 1. 76 ± 0. 76 points, respectively, in the test group, and they were 3. 26 ± 1. 12 and 3. 15 ± 1. 15, respectively, in the con-trol group;both groups presented decreases from the preoperative values ( P<0. 05 ) , with greater decreases in the test group than in the control group (P<0. 05). The postoperative CK levels were (315. 1 ± 91. 5)U/L in the test group and (574. 5 ± 197. 6)U/L in the control group, with statistically significant difference (P<0. 05). Satisfactory rate in experimental group was 90. 1%, which was higher than control group of 79. 6%(P<0. 05). Conclusions It′s more mini-invasive, safe and effective to take the surgery in vertebra-side muscle clearance.关键词
