Oblique Lateral Interbody Fusion

Abstract Background: The objective of the retrospective study was to investigated the incidence and risk factors of low back pain (LBP) in patients with lumbar degenerative disease after single-level oblique lateral interbody fusion(OLIF).Methods: In this retrospective study, 120 patients who undergoing single-level OLIF to treat lumbar degenerative disease were recruited. Preoperative and postoperative radiographic parameters, including segmental lordosis(SL), lumbar lordosis(LL), disk height(DH), pelvic incidence(PI), pelvic tilt (PT), sacral slope(SS), thoracic kyphosis(TK), C7-sagittal vertical axis (SVA). Visual analog scale(VAS) for back and leg pain, and Oswestry Disability Index(ODI), were used to evaluate symptoms and quantify disability. All patients achieved at least two-year follow-up.Results: A total of 120 Patients who complained low back pain were apportioned to LBP group (n=38; VAS scores for back pain≥3) or Non-LBP group (n=82;VAS scores for back pain＜3). There was no difference in age(P=0.082), gender(P=0.425), body mass index(P=0.138), degenerative spondylolisthesis or lumbar spinal stenosis(P=0.529) surgical level(P=0.651), blood Loss (P=0.889) and operative time(P=0.731) between the groups. In both groups, the ODI and VAS scores for back pain and leg pain were significantly improved at the final follow-up compared to the preoperative scores (P=0.003). Furthermore, except for the LBP (P=0.000), there were no significant differences in these scores between the two groups at the final follow-up (P > 0.05). According to the radiographic parameters, in Non-LBP group, the LL, SL, DH, TK and SS had all significantly improved; PT and C7-SVA significantly decreased at the final follow-up compared to the preoperative values. The DH in both groups had significantly improved, no significant difference was found(P=0.325). In the final follow-up, LL, PI-LL, PT and C7-SVA in Non-LBP group had more improvements compared to the LBP group (P＜0.05) . Multivariate analysis showed that PT, PI-LL and C7-SVA were identified as significant risk factors for LBP after OLIF.Conclusion: The clinical outcomes of OLIF for single-level lumbar degenerative disease were satisfactory. Our findings showed that PT, PI-LL mismatch and C7-SVA had the greatest impact on the incidence of LBP. Therefore, patients with appropriate decreased PT, improved C7-SVA and PI-LL match experienced less low back pain.

Abstract Background: We determined the incidence and risk factors of low back pain (LBP) in patients with lumbar degenerative disease after single-level oblique lateral interbody fusion (OLIF). Methods: We retrospectively reviewed 120 lumbar degenerative disease patients who underwent single-level OLIF. We compared preoperative and postoperative radiographic parameters, including segmental lordosis (SL), lumbar lordosis (LL), disk height (DH), pelvic incidence (PI), pelvic tilt (PT), sacral slope (SS), thoracic kyphosis (TK), C7-sagittal vertical axis (SVA). Clinical outcomes were evaluated using Oswestry Disability Index (ODI) scores and visual analog scale (VAS) scores for back and leg pain. All patients were followed up for at least 2 years. Results: Thirty-eight patients had postoperative LBP (VAS score for back pain ≥ 3; LBP group); the remaining 82 patients were in the non-LBP group. Age (P = 0.082), gender (P = 0.425), body mass index (P = 0.138), diagnosis (degenerative spondylolisthesis vs. lumbar spinal stenosis; P = 0.529), surgical level (P = 0.651), blood loss (P = 0.889), and operative time (P = 0.731) did not differ between the groups. In both groups, the ODI and VAS scores for back pain and leg pain significantly improved at the final follow-up compared to the preoperative scores (P = 0.003). Except for the VAS score for back pain (P = 0.000), none of the scores significantly differed between the two groups at the final follow-up (P > 0.05). In the non-LBP group, LL, SL, DH, TK, and SS significantly improved, while PT and C7-SVA significantly decreased at the final follow-up as compared to the preoperative values. In both groups, DH significantly improved postoperatively, with no significant between-group difference (P = 0.325). At the final follow-up, LL, PI-LL mismatch, PT, and C7-SVA showed significantly greater improvement in the non-LBP group than in the LBP group (P < 0.05). Multivariate analysis identified PT, PI-LL mismatch, and C7-SVA as significant risk factors for LBP after OLIF. Conclusion: OLIF for single-level lumbar degenerative disease had satisfactory clinical outcomes. PT, PI-LL mismatch, and C7-SVA were significant risk factors for postoperative LBP. Patients with appropriately decreased PT, improved C7-SVA, and PI-LL match experienced less LBP.

OBJECTIVE Opioid analgesics have become some of the most prescribed drugs in the world, despite the lack of long-term studies evaluating the benefits of opioid medications versus their risks associated with chronic use. In addition, long-term opioid use may be associated with worse long-term clinical outcomes. The primary objective of this study was to evaluate whether preoperative opioid use predicted inferior clinical outcomes among patients undergoing transforaminal lumbar interbody fusion (TLIF) for symptomatic lumbar degenerative disc disease. METHODS The authors of this observational study prospectively enrolled 93 patients who underwent 1-level to 2-level TLIFs in 2011–2014; the patient cohort was divided into 2 groups according to preoperative opioid use or no such use. Visual analog scale (VAS) scores for low-back pain and leg pain, Oswestry Disability Index scores, and the scores of the mental component summary (MCS) and physical component summary (PCS) on the 36-Item Short Form Health Survey were used to assess pain, disability, and health-related quality of life outcomes, respectively. The clinical scores for the 2 groups were determined preoperatively and at a 12-month follow-up examination. RESULTS In total, 60 (64.5%) patients took prescribed opioid medications preoperatively. Compared with those not taking opioids preoperatively, these patients had significantly higher VAS scores for low-back pain (p = 0.016), greater disability (p = 0.013), and lower PCS scores (p = 0.03) at the 12-month follow-up. The postoperative MCS scores were also significantly lower (p = 0.035) in the opioid-use group, but these lower scores were due to significantly lower baseline MCS scores in this group. A linear regression analysis did not detect opioid dose–related effects on leg and back pain, disability, and MCS and PCS scores, suggesting that poorer outcomes are not significantly correlated with higher opioid doses taken by the patients. CONCLUSIONS The use of opioid medications to control pain before patients underwent lumbar fusion for degenerative lumbar conditions was associated with less favorable clinical outcomes postoperatively. This is the first study that has demonstrated this association in a homogeneous cohort of patients undergoing TLIF; this association should be studied further to evaluate the conclusions of the present study.

Endoscopic Lumbar Discectomy

Background: Conventional percutaneous endoscopic lumbar discectomy (PELD) with an “insideoutside” technique has 4.3% – 10.3% surgical failure rate, especially in central herniated discs (HDs), migrated HDs, and axillary type HDs. PELD with foraminoplasty has been used for complex HDs. Percutaneous lumbar foraminoplasty (PLF), which is performed with a trephine or bone reamer introduced over a guidewire without a protective working cannula in the original Tessys technique, can quickly cut the hypertrophied bony structure under fluoroscopic guidance, and risk injury to the exiting and traversing nerve roots. Study Design: A prospective cohort study. Setting: Hospital and outpatient surgical center. Objective: To evaluate the outcome and safety of modified PLF-PELD with a specially designed instrument for complex uncontained lumbar HDs. Method: From April of 2007 to April of 2009, 148 patients with uncontained lumbar HDs were treated with modified PLF-PELD. Magnetic resonance imaging (MRI) checkup was performed the next morning after the operation. Outcomes of symptoms were evaluated by follow-up interviews at 3 months, 6 months, one year, and 5 years after surgery. Low back pain and leg pain were measured by visual analog scale (VAS) score (1 – 100). Functional outcomes were assessed by using the Oswestry Disability Index (ODI) and modified MacNab criteria. Result: Follow-up data were obtained from 134 cases, including 14 cases on L3-4, 78 cases on L4-5, and 42 cases on L5-S1. One hundred-eight cases were prolapse type, while 26 cases were sequestration type. Pre-operative symptoms and deficits included nerve root dermatome hypoesthesia in 98 patients (73%), nerve root myotome muscle weakness in 32 patients (23%), and weakening or disappearance of tendon reflex in 43 patients (32%). No case required conversion to an open procedure during the surgery. Low back pain and leg pain were significantly relieved immediately after surgery in all patients. MRI examination showed adequate removal of HD in all patients. VAS scores and ODI values were significantly lower at all time points after surgery than before surgery. The percentage of pain relief in leg pain was significantly higher than that in low back pain (P < 0.01). But there was no significant correlation between duration of the preoperative symptoms and the percentage of pain relief. MacNab scores at 5 years after surgery were obtained from 134 patients. Seventy-five cases were rated “excellent”; 49 were rated “good,” Five patients experienced heavier low back pain, thus being classified as “fair.” Five cases with recurrence were rated “poor.” Preoperative and postoperative (5 years follow-up) related nerve root function status was compared. Sensation and muscle strength recovered significantly (P < 0.01), while tendon reflex was not changed (P = 0.782). No patients had infections. Five patients were complicated with dysesthesia in distribution of the exiting nerve that was all operated at L5-S1. Complaints were reduced one week after treatment with medium frequency pulse electrotherapy. Five cases required a revision surgery after recurrence. Limitations: This is an observational clinical case series study without comparison.

Εισαγωγή: οι ασθενείς που πάσχουν από χρόνια οσφυαλγία ως συνέπεια της νόσου του εκφυλισμένου δίσκου, εκτός από πόνο εμφανίζουν επίσης και διαταραχή της βάδισής τους. Ο σκοπός της μελέτης είναι η αξιολόγηση τόσο των κλινικών δεδομένων με την χρήση κλινικών κλιμάκων αξιολόγησης, όπως Oswestry Disability Index Greek version (ODI), Visual Analog Scale for low back pain and leg pain (VAS) και το Roland Morris Disability Questionnaire Greek Version, όσο και των κινητικών και κινηματικών χαρακτηριστικών κατά την ανάλυση βάδισης σε ασθενείς με χρόνια οσφυαλγία συνεπεία της νόσου του εκφυλισμένου δίσκου (Disc Degenerative Disease), πριν και μετά την εφαρμογή των ειδικών φυσιοθεραπευτικών τεχνικών (τεχνικών θεραπείας δια χειρός).Μεθοδολογία: για τις ανάγκες της μελέτης 75 ασθενείς που έπασχαν από χρόνια οσφυαλγία, χωρίστηκαν τυχαία σε 3 ομάδες των 25 η καθεμιά. Η κάθε ομάδα δέχθηκε 5 συνεδρίες που για την πρώτη ομάδα ήταν φυσικοθεραπευτικές τεχνικές δια χειρός, για τη δεύτερη ήταν εικονική θεραπεία και για την τρίτη ήταν κλασική φυσικοθεραπεία (διατατικές ασκήσεις, T.E.N.S. και μάλαξη). Προκειμένου να αξιολογηθεί η αποτελεσματικότητα της κάθε θεραπείας χρησιμοποιήθηκε η οπτική αναλογική κλίμακα του πόνου, 2 ερωτηματολόγια (Oswestry και Roland Morris) και επίσης ένα οπτικοηλεκτρονικό σύστημα καταγραφής και ανάλυσης της βάδισης (κινητικά και κινηματικά δεδομένα)Αποτελέσματα: η ομάδα που δέχθηκε τεχνικές δια χειρός εμφάνισε στατιστικά σημαντική μείωση του πόνου και των επιπέδων δυσλειτουργίας. Σε παρόμοια αποτελέσματα οδήγησε και η εφαρμογή κλασικής φυσικοθεραπείας, αλλά η ελάττωση ήταν σαφώς μικρότερη σε σχέση με την ομάδα των τεχνικών δια χειρός. Η ομάδα που δέχθηκε εικονική θεραπεία, δεν είχε κάποια στατιστικά σημαντική διαφορά στα επίπεδα πόνου και δυσλειτουργίας. Σχετικά με την αξιολόγηση της βάδισης, οι ασθενείς στο σύνολό τους, παρουσίασαν διαταραγμένη βάδιση με διαφορά στα κινητικά και κινηματικά δεδομένα μεταξύ δεξιάς και αριστερής πλευράς. Μετά την εφαρμογή των θεραπειών, μόνο η ομάδα που δέχθηκε τεχνικές δια χειρός έδειξε τάση προς συμμετρία μεταξύ δεξιάς και αριστερής πλευράς.Συμπεράσματα: σε περιπτώσεις ασθενών που πάσχουν από χρόνια οσφυαλγία συνεπεία της νόσου του εκφυλισμένου δίσκου, η εφαρμογή 5 συνεδριών τεχνικών δια χειρός δείχνει να βελτιώνει τόσο τα επίπεδα πόνου όσο και δυσλειτουργίας, καθώς επίσης και παρουσιάζει τάση προς συμμετρία στη βάδιση.

Abstract Background Effective, inexpensive, and low-risk interventions are needed for patients with nonspecific persistent low back pain (NS-PLBP) who are unresponsive to primary care interventions. Cognitive functional therapy (CFT) is a multidimensional behavioral self-management approach that has demonstrated promising results in primary care and has not been tested in secondary care. Objective To investigate the effect of CFT and compare it with usual care for patients with NS-PLBP. Design Case–control study. Setting A secondary care spine center. Subjects Thirty-nine patients received a CFT intervention and were matched using propensity scoring to 185 control patients receiving usual care. Methods The primary outcome was Roland Morris Disability Questionnaire (0–100 scale) score. Group-level differences at six- and 12-month follow-up were estimated using mixed-effects linear regression. Results At six-month follow-up, a statistically significant and clinically relevant difference in disability favored the CFT group (–20.7, 95% confidence interval [CI] = –27.2 to –14.2, P &lt; 0.001). Significant differences also occurred for LBP and leg pain, fear, anxiety, and catastrophizing in favor of CFT. At 12-month follow-up, the difference in disability was smaller and no longer statistically significant (–8.1, 95% CI = –17.4 to 1.2, P = 0.086). Differences in leg pain intensity and fear remained significantly in favor of CFT. Treatment satisfaction was significantly higher in the CFT group at six- (93% vs 66%) and 12-month (84% vs 52%) follow-up. Conclusions These findings support that CFT is beneficial for patients with NS-PLBP who are unresponsive to primary care interventions. Subsequent randomized controlled trials could incorporate booster sessions, which may result in larger effects at 12-month follow-up.

Objective. To investigate the short- and long-term effects of electroacupuncture (EA) compared with medium-frequency electrotherapy (MFE) on chronic discogenic sciatica.Methods. One hundred participants were randomized into two groups to receive EA (n=50) or MFE (n=50) for 4 weeks. A 28-week follow-up of the two groups was performed. The primary outcome measure was the average leg pain intensity. The secondary outcome measures were the low back pain intensity, Oswestry Disability Index (ODI), patient global impression (PGI), drug use frequency, and EA acceptance.Results. The mean changes in the average leg pain numerical rating scale (NRS) scores were 2.30 (1.86–2.57) and 1.06 (0.62–1.51) in the EA and MFE groups at week 4, respectively. The difference was significant (P<0.001). The long-term follow-up resulted in significant differences. The average leg pain NRS scores decreased by 2.12 (1.70–2.53) and 0.36 (−0.05–0.78) from baseline in the EA and MFE groups, respectively, at week 28. However, low back pain intensity and PGI did not differ significantly at week 4. No serious adverse events occurred.Conclusions. EA showed greater short-term and long-term benefits for chronic discogenic sciatica than MFE, and the effect of EA was superior to that of MFE. The study findings warrant verification. This trial was registered under identifierChiCTR-IPR-15006370.

Background. Comparison of single-level open and minimally invasive transforaminal lumbar interbody fusions (O-TLIF and MI-TLIF) of a single surgeon and presentation of his MI-TLIF learning curve in a retrospective observational cohort study. Methods. 27 MI-TLIF and 31 O-TLIF patients, performed between 03/01/2013 and 03/31/2018, were compared regarding the operative time, blood loss, blood transfusion frequency, postoperative length of stay (LOS), and adverse events. An overall comparison of pre- and postoperative Oswestry Disability Index (ODI) results and Visual Analog Score (VAS) results of low back and leg pain was performed in the case of the two techniques. For a learning curve presentation, the MI-TLIF cases were compared and the optimal operative time was determined. Results. The gender ratio and age did not differ in the groups. Operative time showed no difference (P=0.88) between the MI-TLIF (161.2 ± 33.7 minutes) and O-TLIF groups (160 ± 33.6 minutes). Intraoperative blood loss was less (P≤0.001) in the MI-TLIF group (288.9 ± 339.8 mL) than in the O-TLIF group (682.3 ± 465.4 mL) while the incidence of blood transfusion was similar (P=0.64). The MI-TLIF group had shorter LOS (2.7 ± 1.1 days vs. 5 ± 2.7, P≤0.001). The frequencies of the surgical site infections (SSI), durotomy, new motor, and sensory deficit were not significantly different (P=0.17, 0.5, 0.29, 0.92). All the ODI, the VAS low back pain, and the VAS leg pain scores improved in both groups significantly (P≤0.001, P≤0.001, and P≤0.001 in the MI-TLIF group and P≤0.001, P≤0.001, and P≤0.001 in the O-TLIF group). The comparison of the pre- and postoperative results of the ODI and VAS questionnaires of the two techniques showed no significant difference regarding the improvement of these scores (MI-TLIF versus O-TLIF pre- and postoperative ODI difference p=0.64, VAS low back pain P=0.47, and VAS leg pain P=0.21). Assessing the MI-TLIF learning curve, operative time was shortened by 63 minutes (P=0.04). After the 14th MI-TLIF case, the surgical duration became relatively constant. Comparing the 14th and previous MI-TLIF cases to the later cases, LOS showed reduction by 1.03 days (P=0.01), while the other parameters did not show significant changes. Conclusions. Similar operative time and postoperative quality of life improvement can be achieved by MI-TLIF procedure as with O-TLIF, and additionally LOS and blood loss can be reduced. When comparing parameters, MI-TLIF can be an alternative option for O-TLIF with a similar complication profile. The learning curve of MI-TLIF can be steep, although it depends on the circumstances.
