ABSTRACT OBJECTIVE We sought to compare the clinical and radiological results of instrumented posterior lumbar interbody fusion (PLIF) using unilateral or bilateral polyetheretherketone cages and pedicle screws. METHODS One hundred eighty-seven cases of degenerative spine that had been followed for at least 18 months were reviewed retrospectively. In 88 cases (147 levels), one cage was inserted, and in 99 cases (152 levels), two cages were inserted. Visual analog scale, Oswestry disability index, and functional rating indices were measured. Lumbar lordosis, lumbar scoliotic and fusion level scoliotic angles, and stable fixation were determined before surgery and 12 months postoperatively on standing x-rays. Amounts of intra- and postoperative blood loss, total quantities transfused, and operation times were also evaluated. RESULTS No significant differences were found between the two groups in terms of visual analog scale, Oswestry disability index, functional rating indices, lumbar lordosis, lumbar scoliotic angles, fusion level scoliotic angles, or fixation stabilities. However, the amounts of postoperative blood loss, total blood loss, and total transfusion for two-level PLIF using a unilateral cage were statistically smaller than those for two-level PLIF using bilateral cages. Times required for PLIF using a unilateral cage were also significantly shorter than those for PLIF using bilateral cages. CONCLUSION Unilateral cage and bilateral pedicle screw insertion may be a good alternative surgical option because it provides adequate alignment, balance, and mechanical stability in addition to reducing operative time, blood loss, and transfusion requirements.

OBJECTIVE Tranexamic acid (TXA), a synthetic antifibrinolytic drug, has been reported to reduce blood loss in orthopedic surgery, but there have been few reports of its use in spine surgery. Previous studies included limitations in terms of different TXA dose regimens, different levels and numbers of fused segments, and different surgical techniques. Therefore, the authors decided to strictly limit TXA dose regimens, surgical techniques, and fused segments in this study. There have been no reports of using TXA for prevention of intraoperative and postoperative blood loss in posterior lumbar interbody fusion (PLIF). The purpose of the study was to evaluate the efficacy of high-dose TXA in reducing blood loss and its safety during single-level PLIF. METHODS The study was a nonrandomized, case-controlled trial. Sixty consecutive patients underwent single-level PLIF at a single institution. The first 30 patients did not receive TXA. The next 30 patients received 2000 mg of intravenous TXA 15 minutes before the skin incision was performed and received the same dose again 16 hours after the surgery. Intra- and postoperative blood loss was compared between the groups. RESULTS There were no statistically significant differences in preoperative parameters of age, sex, body mass index, preoperative diagnosis, or operating time. The TXA group experienced significantly less intraoperative blood loss (mean 253 ml) compared with the control group (mean 415 ml; p < 0.01). The TXA group also had significantly less postoperative blood loss over 40 hours (mean 321 ml) compared with the control group (mean 668 ml; p < 0.01). Total blood loss in the TXA group (mean 574 ml) was significantly lower than in the control group (mean 1080 ml; p < 0.01). From 2 hours to 40 hours, postoperative blood loss in the TXA group was consistently significantly lower. There were no perioperative complications, including thromboembolic events. CONCLUSIONS High-dose TXA significantly reduced both intra- and postoperative blood loss without causing any complications during or after single-level PLIF.

Oblique Lumbar Interbody Fusion

OBJECTIVEDirect neural decompression cannot be achieved by performing lateral lumbar interbody fusion (LLIF). To overcome the indirect decompressive effect of LLIF, additional endoscopic discectomy with oblique lumbar interbody fusion (OLIF) has been attempted. The purpose of this study was to assess the clinical and radiological outcomes of patients who underwent OLIF with additional endoscopic discectomy.METHODSSpinal endoscopic discectomy–assisted OLIF was attempted to remove herniated disc material. Only patients with a follow-up time that exceeded 12 months were enrolled. Clinical parameters examined were the Oswestry Disability Index and visual analog scale scores of back and leg pain. Postoperative MRI was also performed.RESULTSFourteen patients were enrolled. Central and foraminal disc herniations were evident in 8 and 6 patients, respectively. Concomitant central or foraminal herniated discs were removed completely after additional endoscopic discectomy, and disc removal was confirmed by postoperative MRI. Mean preoperative visual analog scale scores and Oswestry Disability Index scores improved postoperatively.CONCLUSIONSOLIF with additional endoscopic discectomy results in successful direct neural decompression without posterior decompressive procedures. Endoscopic assistance might overcome the limitations of LLIF.

Abstract BACKGROUND In minimally invasive transforaminal lumbar interbody fusion (MIS-TLIF), cage type and position play important roles in fusion achievement and sagittal alignment correction. However, no prospective randomized comparison of the results using different types of cage has been reported to date. OBJECTIVE To compare the radiological and clinical outcomes of unilateral MIS-TLIF using 2 types of cage. METHODS All candidates for single-level MIS-TLIF were randomized into banana-shaped cage and straight-cage groups. Plain radiographs and computed tomography scans were used for assessment of cage positions, fusion status, disc height, segmental lordotic angle, cage subsidence, and pelvic parameters. Clinical outcome was assessed using visual analog scale and Oswestry Disability Index scores. RESULTS Forty-four and 40 consecutive patients were operated on using banana-shaped and straight cages, respectively. Cage position was more anterior and lateral in the straight-cage group and more medial and posterior in the banana-shaped cage group. Solid fusion was achieved in 95.2% and 96.6% of the 2 groups, respectively, at 12 mo. The change in disc height and segmental lordotic angle postoperatively was significantly greater in the banana-shaped cage group. The incidence of subsidence during follow-up was significantly higher in the banana-shaped cage group (P &lt; .04). Clinically, the visual analog scale and Oswestry Disability Index scores decreased significantly after surgery in both groups, with no significant difference between the groups. CONCLUSION Our preliminary outcomes suggest that the subsidence rate may be higher using banana-shaped cages in MIS-TLIF, possibly due to their more medial final position.

Study Design: Systematic review and meta-analysis. Objectives: Arthrodesis has been a valid treatment option for spinal diseases, including spondylolisthesis and lumbar spinal stenosis. Posterolateral and posterior lumbar interbody fusion are amongst the most used fusion techniques. Previous reports comparing both methods have been contradictory. Thus, we conducted a systematic review and meta-analysis of randomized controlled trials (RCTs) to establish substantial evidence on which fusion method would achieve better outcomes. Methods: Major databases including PubMed, Embase, Web of Science and CENTRAL were searched to identify studies comparing outcomes of interest between posterolateral fusion (PLF) and posterior lumbar interbody fusion (PLIF). We extracted data on clinical outcome, complication rate, revision rate, fusion rate, operation time, and blood loss. We calculated the mean differences (MDs) for continuous data with 95% confidence intervals (CIs) for each outcome and the odds ratio with 95% confidence intervals (CIs) for binary outcomes. P < 0.05 was considered significant. Results: We retrieved 8 studies meeting our inclusion criteria, with a total of 616 patients (308 PLF, 308 PLIF). The results of our analysis revealed that patients who underwent PLIF had significantly higher fusion rates. No statistically significant difference was identified in terms of clinical outcomes, complication rates, revision rates, operation time or blood loss. Conclusions: This systematic review and meta-analysis provide a comparison between PLF and PLIF based on RCTs. Although PLIF had higher fusion rates, both fusion methods achieve similar clinical outcomes with equal complication rate, revision rate, operation time and blood loss at 1-year minimum follow-up.

Abstract OBJECTIVE Minimal access surgery as a less invasive alternative to standard macro- and microsurgical approaches is becoming increasingly popular in the management of traumatic and degenerative spine diseases. However, data is lacking if minimal access spine surgery is indeed beneficial. This prospective randomized study was conducted to compare efficiency, safety, and outcome of standard open microsurgical discectomy (SOMD) for lumbar disc herniation with microsurgical discectomy using an 11.5 mm trocar system for minimal access to the spine. METHODS Sixty patients were randomized to two groups of 30 patients each. Group 1 was treated by SOMD, and Group 2 was treated by minimal access microsurgical discectomy (MAMD). Perioperative parameters and pre- and postoperative clinical findings including sensory or motor deficits and pain according to the visual analog scale, Oswestry Disability Index scores, and Short Form-36 results were assessed. All patients were followed for at least 6 months postoperatively (mean, 16 mo). RESULTS Preoperatively, no statistically significant intergroup differences could be detected proving the comparability of both groups. Postoperatively, significant improvement of neurological symptoms and pain as measured by the visual analog scale, Oswestry Disability Index, and Short Form-36 scores could be achieved in both groups. In regard to operative time, intraoperative blood loss, and complication rate, slightly better results were observed in the MAMD group. CONCLUSION SOMD and MAMD allow achievement of significant improvement of pain and neurological deficits in patients with lumbar disc herniations. Differences in operative time, blood loss, and complication rates were statistically not significant in MAMD compared with SOMD, indicating that, at least in lumbar disc surgery, minimal access trocar techniques are a viable alternative to standard spinal approaches.

The aim of this study was to directly compare the clinical outcomes of posterior lumbar interbody fusion (PLIF) and minimally invasive transforaminal lumbar interbody fusion (MIS-TLIF) in three-level lumbar spinal stenosis. This retrospective study involved a total of 60 patients with three-level degenerative lumbar spinal stenosis who underwent MIS-TLIF or PLIF from January 2010 to February 2012. Back and leg visual analog scale (VAS), Oswestry Disability Index (ODI), and Short Form-36 (SF-36) scale were used to assess the pain, disability, and health status before surgery and postoperatively. In addition, the operating time, estimated blood loss, and hospital stay were also recorded. There were no significant differences in back VAS, leg VAS, ODI, SF-36, fusion condition, and complications at 12-month follow-up between the two groups (P>0.05). However, significantly less blood loss and shorter hospital stay were observed in MIS-TLIF group (P<0.05). Moreover, patients undergoing MIS-TLIF had significantly lower back VAS than those in PLIF group at 6-month follow-up (P<0.05). Compared with PLIF, MIS-TLIF might be a prior option because of noninferior efficacy as well as merits of less blood loss and quicker recovery in treating three-level lumbar spinal stenosis.
