Abstract:
OBJECTIVETo compare the short-term clinical outcome between unilateral fixation fusion (ULF) and minimally invasive spine transforaminal lumbar interbody fusion (MIS-TLIF) in treating lumbar disc herniation (LDH).
METHODSThe clinical data of 39 patients with LDH were retrospectively analyzed from June 2008 to March 2013. There was 22 males and 17 females, aged from 45 to 75 years old with an average of 56.9 years. Therer were 3 cases in L3,4, 15 cases in L4,5, 21 cases in L5S1. Among them, 21 patients underwent unilateral fixation fusion (ULF group) and 18 underwent minimally invasive spine transforaminal lumbar interbody fusion (MIS-TLIF group). Operation time, blood loss, the times of radiographic exposure and hospital stay were noted and compared between two groups. Radiograph informations were regularily accessed and VAS, ODI scores were recorded at 3 days and 3, 6, 12 months after operation, respectively. According to modified Macnab criteria, the clinical effects were evaluated at final follow-up.
RESULTSAll operations were successful without severe complications. The averaged operative time and the times of radiographic exposure in ULF group [(95 ± 25) min and (4.2 ± 0.4) times] were less than that of MIS-TLIF group [(120 ± 35) min and (10.1 ± 3.9) times] (P < 0.05). But, the mean blood loss and hospital stay in MIS-TLIF group [(75 ± 45) ml and (7.2 ± 2.2)d ]were less than that of ULF group [(165 ± 60) ml and (11.0 ± 3.7) d] (P < 0.01). All patients were followed up from 12 to 45 months with an average of 29.5 months. The VAS and ODI score had significantly improved during the follow-up and no significant differences were found between two groups at the same time point (P > 0.05). The postoperative radiographs showed internal fixation position was good. And all patients obtained bone fusion by CT scan at 1 year after operation. There was no significant differences in modified Macnab criteria between two groups at the latest follow-up (P > 0.05).
CONCLUSIONFavorable short-term clinical effects can be achieved in suitable LDH patients with ULF or MIS-TLIF surgical procedures.
