Abstract:
OBJECTIVE:To investigate the advantages of minimally invasive surgery-transforaminal lumbar interbody fusion(MIS-TLIF) under Quadrant channel in the treatment of grade I and II degree degenerative lumbar spondylolisthesis.
METHODS:The clinical data of 100 patients with grade I and II degree degenerative lumbar spondylolisthesis treated from March 2014 to March 2017 were retrospectively analyzed. Among them, 50 patients were treated with MIS-TLIF, including 19 males and 31 females, aged from 44 to 73 years old with an average of (49.83±15.46) years old; course of disease from 6 months to 7 years with the mean of (22.18±4.74) months; L₄ slippage was in 30 cases and L₅ slippage was in 20 cases, the slippage vertebral pedicles were intact; according to Meyerding classification, 29 cases of I degree slip and 21 cases of II degree slip. Other 50 patients were treated with open-transforaminal lumbar interbody fusion(OPEN-TLIF), including 23 males and 27 females, aged from 40 to 77 years old with an average of(50.67±14.36) years old; course of disease from 6 months to 10 years with the mean of (20.56±5.37) months; L₄ slippage was in 33 cases and L₅ slippage was in 17 cases, the slippage vertebral pedicles were intact; according to Meyerding classification, 34 cases of I degree slip and 16 cases of II degree slip. The operation time, length of surgical incision, intraoperative blood loss, postoperative drainage, and serum creatine kinase(CK-MM) levels before surgery and 1 day after surgery were observed. Visual analogue scale(VAS), Japanese Orthopedic Association Score (JOA), and Oswestry dysfunction index (ODI) were compared between the two groups before and after surgery. According to the imaging data, the slip rate, intervertebral space height and slip angle of the two groups before and 12 months (last follow-up) were compared. Intervertebral fusion was evaluated according to lumbar X-ray and CT at 6 and 12 months postoperatively. The clinical effect was evaluated according to the MacNab criteria at 12 months after surgery.
RESULTS:All the patients were followed up for 12 months. In MIS-TLIF group, operation time, length of surgical incision, intraoperative blood loss, postoperative drainage were (118.48±21.97) min, (3.74±0.74) cm, (148.78±32.32) ml, (84.85±16.37) ml, respectively, CK-MM level was (72.31±9.79) μ/L before surgery and (415.12±25.89) μ/L at the first day after surgery. In OPEN-TLIF group, operation time, length of surgical incision, intraoperative blood loss, postoperative drainage were (115.40±11.94) min, (8.46±0.69) cm, (219.27±48.33) ml, (157.69±31.61) ml, respectively, CK-MM level was (75.48±10.73) μ/L before surgery and (506.69±37.86) μ/L at the first day after surgery. The intraoperative blood loss, postoperative drainage volume, length of surgical incision, and CK-MM level on the first postoperative day were lower in MIS-TLIF group than in OPEN-TLIF group(<0.05), but the operation time and preoperative CK-MM levels were compared between two groups, the difference was not statistically significant (>0.05). There were no significant differences in ODI, VAS, and JOA scores before surgery(>0.05). The ODI, VAS, and JOA scores were significantly improved after surgery(<0.05), and the scores of MIS-TLIF group were better than those of OPEN-TLIF group(<0.05). At the last follow-up, the slip rate, slip angle and intervertebral space height were significantly improved in the same group(<0.05), but there was no significant difference between two groups(>0.05). There was no significant difference in intervertebral fusion between groups at 6 and 12 months after operation(>0.05). According to the MacNab standard, 40 cases got excellent results, 7 good, 3 fair in MIS-TLIF group, and 35 cases got excellent results, 10 good, 5 fair in OPEN-TLIF group. One patient had incision exudation and delayed healing in MIS-TLIF group. And in OPEN-TLIF group, 1 patient had local muscle necrosis on the right side of L₅ and the bacterial culture of the secretions was negative in the different three times and the right internal fixation device was taken out after the second operation completely debridement, and finally obtained delayed healing.
CONCLUSIONS:The MIS-TLIF under Quadrant channel has advantage of minimally invasive trauma, less bleeding, faster function recovery and better effect in surgical treatment of grade I and II degree degenerative lumbar spondylolisthesis.
