Objective is to describe a safe and effective percutaneous endoscopic approach for removal of highly migrated and sequestrated disc herniations of the upper lumbar spine and to report the results, surgical indications, and technical considerations of the new technique. Eleven patients who had highly migrated and sequestrated disc herniations in the upper lumbar were included in this study. A retrospective study was performed for all patients after translaminar osseous channel-assisted PELD was performed. Radiologic findings were investigated, and pre-and postoperative visual analog scale (VAS) assessments for back and leg pain and Oswestry disability index (ODI) evaluations were performed. Surgical outcomes were evaluated under modified MacNab criteria. All of the patients were followed for more than 1 year. The preoperative and postoperative radiologic findings revealed that the decompression of the herniated nucleus pulposus (HNP) was complete. After surgery, the mean VAS scores for back and leg pain immediately improved from 8.64 (range, 7–10) and 8.00 (range, 6–10) to 2.91 (range, 2–4) and 2.27 (range, 1–3), respectively. The mean preoperative ODI was 65.58 (range, 52.2–86), which decreased to 7.51 (range, 1.8–18) at the 12-month postoperative follow-up. The MacNab scores at the final follow-up included nine excellent, one good, and one fair. The modified translaminar osseous channel-assisted PELD could be a safe and effective option for the treatment of highly migrated and sequestrated disc herniations of the upper lumbar.

Background and Study Aims Although transforaminal percutaneous endoscopic lumbar diskectomy (PELD) offers certain advantages in the treatment of disk herniations, it used to be limited to nonmigrated or low-migrated herniations. With improvements in endoscopic spinal surgery, the range of indications for PELD has expanded. Various techniques including transforaminal and interlaminar approaches for migrated disk herniations are described in the literature. This study describes a transforaminal PELD approach to address downmigrated intracanal soft disk herniations effectively using the lever-up, rotate, and tilt technique. Patients and Methods We performed a retrospective review of 18 patients who had been operated on with the described technique between October 2012 and December 2015. We assessed clinical outcomes using the visual analog scale (VAS) for back and leg pain and the Oswestry Disability Index (ODI) preoperatively at their respective clinical visits and postoperatively at the patients' final follow-up examinations. Results The mean preoperative VAS scores for back and leg pain were 3.75 + 1.34 (range: 2–6) and 8.3 + 0.6 (range: 8–10), respectively. The mean preoperative ODI was 67.3 + 15.3 (range: 48–90). The mean VAS scores for back and leg pain improved to 1.38 + 1.58 (range: 0–6) and 1.19 + 0.75 (range: 0–3), respectively, at the last follow-up. The mean ODI also improved to 14.1 + 6.2 (range: 8–30) at the last follow-up. All differences between the preoperative and last follow-up scores were statistically significant (p < 0.05), Two surgeries failed because of a remnant disk fragment. Conclusions The lever-up, rotate, and tilt technique for transforaminal PELD is an effective maneuver to treat downmigrated disk herniations in selected patients by experienced surgeons.

Study Design: A prospective cohort study in a high-flow spine center in Germany. Objectives: This study aimed to evaluate clinical outcomes and complications of the trans-tubular translaminar microscopic-assisted percutaneous nucleotomy in cases of cranially migrated lumbar disc herniations (LDH). Methods: Between January 2013 and January 2018, 66 consecutive patients with cranio-laterally migrated LDH were operated upon. The following outcome measures were evaluated: (1) Visual Analog Scale (VAS) for leg and back pain; (2) Oswestry Disability Index (ODI) and Macnab´s criteria. All patients were operated upon with trans-tubular Translaminar Microscopic-assisted Percutaneous Nucleotomy (TL-MAPN). Perioperative radiographic and clinical evaluations were reported. The mean follow-up period was 32 months. Results: The mean age was 59 years. L4/L5 was the commonest affected level (27 patients). The mean preoperative VAS for leg pain was 6.44 (±2.06), improved to 0,35 (±0.59) postoperatively. Dural injury occurred in 1 patient, treated with dural patch. Improved neurological function was reported in 41/44 Patients (neurological improvement rate of 93%) at the final follow up. There was a significant improvement in the mean ODI values, from 50.19 ± 4.92 preoperatively to 10.14 ± 2.22 postoperatively (P < 0.001). Sixty four out of 66 patients (96%) showed an excellent or good functional outcome according to Macnab´s criteria. No recurrent herniations were observed. Conclusion: The translaminar approach is a viable minimal invasive technique for cranially migrated LDH. The preservation of the flavum ligament is one of the main advantages of this technique. It is an effective, safe and reproducible minimally invasive surgical alternative in treatment of cranially migrated LDHs.

Objective: To evaluate the efficacy of intraoperative three-dimensional (3D) Iso-C C-arm- navigated percutaneous radiofrequency ablation (RFA) of osteoid osteomas.Methods: 35 patients (20 males and 15 females) with osteoid osteomas underwent treatment with intraoperative 3D Iso-C C-arm navigation-guided RFA. The tumour was first biopsied for pathological examination, the core needle was removed and the RFA needle was inserted into the nidus. Post-operative X-rays and CT scans were performed to evaluate the degree of ablation and to assess for recurrence at 3-month follow-up. Patients also completed a visual analogue scale (VAS) both pre-operatively and 3 days post-operatively to subjectively assess pain.Results: Pathological diagnosis confirmed osteoid osteoma in 19 cases. The other 16 cases were not pathologicallydiagnosed owing to inadequate biopsy specimens. In all cases, localized pain was immediately relieved following RFA. Patients reported significantly decreased pain, with mean pre- operative VAS scores of 3.4 reducing to 0.80 at 3 days post-operatively and further to 0.06 at 3-month follow-up (p ,0.05). The mean follow-up time was 15.5 months (range: 3–38 months).Conclusion: 3D Iso-C C-arm navigation-guided RFA is a safe and effective option for the treatment of osteoid osteomas and may be considered in place of intra-operative CT-guided and open resection.Advances in knowledge: C-arm image-guided percutaneous RFA mitigates the need for pre- operative CT as well as intraoperative scintigraphy, provides real-time imaging of the anatomy, facilitates accurate resection of the tumour and enables immediate confirmation of excision.

Abstract Background: To assess the efficacy of the superior notch of inferior vertebral pedicle approach of transforaminal percutaneous endoscopic lumbar discectomy for very high-grade inferiorly migrated disc herniation.Methods: Data on 32 consecutive patients operated with percutaneous endoscopic surgery via the superior notch of inferior vertebral pedicle approach were reviewed. Age, gender, clinical diagnoses, operation time, hospitalization time, a self-administered questionnaire composed of the leg pain visual analogue scale (VAS leg pain) and the Oswestry Disability Index (ODI) had been recorded before operation and 1, 3, 6 and 12 months after operation, respectively. The clinical results were assessed at the final follow-up by using modified Macnab criteria. Complications were recorded during follow-up, and postoperative X-ray, CT and MRI examinations were performed.Results: There were 21 males and 11 females. The mean age of patients was 51.8±10.6 years. MRI findings of patients with disc herniation were L2-3 level in 4 case, L3-4 level in 9 cases and L4-5 level in 19 cases, which were correlated with clinical symptoms. All patients completed a 12-month follow-up assessment after surgery. The mean operative duration was 68.2±12.8 min, and hospitalization time was 3.6±0.8 days. At 12 months follow up the VAS leg pain had improved by 6.3 (P< 0.05) and the ODI by 43.6 points (P< 0.05). Twenty-three cases (71.9%) were rated as excellent, 7 (21.9%) as good, 2 (6.2%) as fair at the final follow-up. On the basis of the modified MacNab criteria, the overall excellent and good rate was 93.8%. Two patients (6.2%) had transient dysesthesia after surgery. Postoperative radiological evaluations showed no signs of instability or recurrence of pathology.Conclusion: Transforaminal percutaneous endoscopic lumbar discectomy via the superior notch of inferior vertebral pedicle approach could be a safe and effective minimally invasive technique for very high-grade inferiorly migrated disc herniation. This technique warrants further study and clinical application.

OBJECTIVEThe pedicle screw–based Dynesys dynamic stabilization (DDS) has reportedly become a surgical option for lumbar spondylosis and spondylolisthesis. However, it is still unclear whether the dynamic construct remains mobile or eventually fuses. The aim of this study was to investigate the incidence of unintended facet arthrodesis after DDS and its association with spondylolisthesis.METHODSThis retrospective study was designed to review 105 consecutive patients with 1- or 2-level lumbar spondylosis who were treated with DDS surgery. The patients were then divided into 2 groups according to preexisting spondylolisthesis or not. All patients underwent laminectomies, foraminotomies, and DDS. The clinical outcomes were measured using visual analog scale (VAS) scores for back and leg pain, Japanese Orthopaedic Association (JOA) scores, and Oswestry Disability Index (ODI) scores. All medical records, including pre- and postoperative radiographs, CT scans, and MR images, were also reviewed and compared.RESULTSA total of 96 patients who completed the postoperative follow-up for more than 30 months were analyzed. The mean age was 64.1 ± 12.9 years, and the mean follow-up duration was 46.3 ± 12.0 months. There were 45 patients in the spondylolisthesis group and 51 patients in the nonspondylolisthesis group. The overall prevalence rate of unintended facet fusion was 52.1% in the series of DDS. Patients with spondylolisthesis were older (67.8 vs 60.8 years, p = 0.007) and had a higher incidence rate of facet arthrodesis (75.6% vs 31.4%, p < 0.001) than patients without spondylolisthesis. Patients who had spondylolisthesis or were older than 65 years were more likely to have facet arthrodesis (OR 6.76 and 4.82, respectively). There were no significant differences in clinical outcomes, including VAS back and leg pain, ODI, and JOA scores between the 2 groups. Furthermore, regardless of whether or not unintended facet arthrodesis occurred, all patients experienced significant improvement (all p < 0.05) in the clinical evaluations.CONCLUSIONSDuring the mean follow-up of almost 4 years, the prevalence of unintended facet arthrodesis was 52.1% in patients who underwent DDS. Although the clinical outcomes were not affected, elderly patients with spondylolisthesis might have a greater chance of facet fusion. This could be a cause of the limited range of motion at the index levels long after DDS.

Background: As a newly emerging technique, endoscopic transforaminal lumbar interbody fusion (Endo-TLIF) has become an increasingly popular procedure of interest. The purpose of this study was to introduce a modified Endo-TLIF system and share our preliminary clinical experiences and outcomes in treating lumbar degenerative disease with this procedure.Methods: Ninety-six patients (thirty-seven men and fifty-nine women; mean age 55.85 ± 11.03 years) with lumbar degenerative diseases who underwent Endo-TLIF in our hospital were enrolled. The surgical time, volume of intraoperative blood loss, postoperative hospitalization time and postoperative drainage were documented. Clinical outcomes were evaluated by visual analog scale (VAS) scores, Oswestry Disability Index (ODI) scores, and modified MacNab criteria. Bone fusion was identified through computerized tomography (CT) scans or X-ray during the follow-up period.Results: All patients were followed up for at least 12 months, and the average follow-up time was 17.03 ± 3.27 months. The mean operative time was 136.79 ± 30.14 minutes, and the mean intraoperative blood loss was 53.06 ± 28.89 ml. The mean VAS scores of low back pain and leg pain were 5.05 ± 1.37 and 6.25 ± 1.03, respectively, before surgery, which improved to 2.27 ± 0.66 and 2.22 ± 0.55, respectively, after the operation (P &lt; 0.05). The final VAS scores of low back pain and leg pain were 0.66 ± 0.60 and 0.73 ± 0.66, respectively (P &lt; 0.05). The preoperative ODI score (49.06 ± 6.66) also improved significantly at the 3-month follow-up (13.00 ± 7.37; P &lt; 0.05). The final ODI score was 8.03 ± 6.13 (P &lt; 0.05). There were 10 cases of non-fusion (nine women and one man) at the 12-month follow-up, but no cases of non-union were identified by imaging at the final follow-up.Conclusions: The present study demonstrated satisfactory clinical and radiologic results among patients who received Endo-TLIF treatment from our institution. This indicates that Endo-TLIF is efficient and safe for select patients.

Following lumbar fusion, adjacent segment degeneration has been frequently reported. Dynamic systems are believed to reduce main fusion drawbacks. We conducted a retrospective study on patients with degenerative lumbar disease treated with posterior dynamic stabilization with monoaxial hinged pedicular screws and lumbar decompression. VAS and ODI were used to compare clinical outcomes. As radiological outcomes, LL and SVA were used. 51 patients were included with an average follow-up of 24 months. 13 patients were revised because of postoperative radiculopathy (n=4), subcutaneous hematoma(n=2), L5 screw malposition (n=1) and adjacent segment disease (n=6). The mean ODI score 41 preoperatively compared to 36 postoperatively. The mean VAS scores for back and leg pain were 5.3 and 4.2, respectively compared to 4.5 and 4.0 post-operatively. The mean SVA was 5.3 cm pre-operatively, and 5.7 cm postoperatively. The mean LL was 47.5° preoperatively and 45.5° postoperatively. From our data, whichfail to show significant improvements andreflect a high revision rate, we cannot generally recommend dynamic stabilization as an alternative to fusion. Comparative trials with longer follow-ups are required.

Study Design: Retrospective cohort study. Objectives: Discectomy alone or discectomy with fusion have been 2 polarized options in the management of large lumbar disc herniations presenting with leg-dominant pain in young patients. The objective of the study was to evaluate the outcomes of discectomy in young patients with large central lumbar disc herniation (CLDH) presenting with predominant leg pain. Material and Methods: Young patients (<45 years) presenting with predominant leg pain and MRI confirmed diagnosis of CLDH between April 2007-January 2017 were included in the study. All patients underwent tubular microdiscectomy. Outcomes of surgery were evaluated using visual analogue score (VAS) for leg and back pain, Oswestry Disability Index (ODI), and Macnab’s criteria. Results: Ninety patients fulfilled the inclusion criteria. The mean age of patients was 34.9 years (range 19-45 years). Mean follow-up was 5.09 years (range 2-10 years). The incidence of CLDH in young adults was 30% and incidence among all “operated” lumbar disc herniations was 15.9%. The mean VAS for leg pain improved from 7.48 ± 0.9 to 2.22 ± 0.84 ( P < .05) and the mean ODI changed from 60.53 ± 7.84 to 18.33 ± 6.20 ( P < .05). Fifty-nine patients (65.6%) reported excellent, 25 patients (27.8%) reported good, 3 patients each (3.3%) as fair and poor outcomes respectively. Conclusion: Discectomy alone for CLDH with predominant leg pain is associated with high success rate and low need for a secondary surgical procedure. Patient selection in terms of leg-dominant pain may be the main attribute for lower incidence of recurrence, postoperative back-pain, and instability needing a secondary procedure. Minimally invasive discectomy may provide an added advantage of preserving normal spinal anatomy, thus minimizing the need for primary spinal fusion in these patients.

Background:Pediatric to adult rheumatology transition can be a challenge for both the patient and the clinician, especially in rheumatology as it includes chronic diseases with close follow-up.Objectives:The objective of this study is to understand our tertiary rheumatology center patient demographic transitioning from pediatric to adult rheumatology in order to design prospective studies enhancing the evidence of transition recommendations.Methods:Patients included in this study are regularly followed-up in our adult rheumatology clinic and were regularly followed up in our pediatric rheumatology clinic in the past. They were all diagnosed with a rheumatologic condition receiving treatment. The patient files were assessed to have a better understanding of their demographic, disease and treatment information.Results:Our cohort includes 347 patients diagnosed with a variety of conditions that are Familial Mediterranean Fever (FMF) (n=216), Juvenile Idiopathic Arthritis (JIA) (n=56), Juvenile Spondyloarthritis (jSPA) (n=39), Systemic Lupus Erythematosus (SLE) (n=20), Behçet’s Disease (n=7) and the rest of the rheumatologic conditions with less than 5 patients each. The mean age of the patients during transition, mean age of diagnosis, and follow-up duration are 21.34±1.7, 10.4±4.18, and 10.82±4.4 in respective order. The treatment regimens the patients received are summarized in Table 1.Table 1.Current Treatment Information of the PatientsCurrent Treatment InformationDMARD26Colchicine23Adalimumab21Etanercept10NSAID4Tocilizumab3Cyclophosphamide3Rituximab2Prednisolone7Mycophenolate Mofetil1Canakinumab1Seven patients had FMF related attacks. In addition to attacks, one FMF patient had bilateral ankle pain and one patient had leg pain. One patient out of three diagnosed with Takayasu’s disease was still symptomatic. One patient had uveitis-related symptoms. One patient diagnosed with SLE had skin dryness. Furthermore, there were patients with sequelae formation. One patient diagnosed with oligoarticular JIA (oJIA) had bilateral hip sequela with the additional left hip prosthesis. One oJIA patient had micrognathia, and one had left knee sequela. One pJIA patient had small joint sequelae. One sJIA patient had bilateral hip sequelae. One jSPA patient had enthesopathy. One FMF patient had proteinuria due to amyloidosis formation. Another FMF patient had hip surgery due to sequela.Conclusion:Our center had patients with a variety of conditions with different natures of diseases. EULAR recommends the transition process to start no later than 14 years of age; however, this process started at the mean age of 21 in our patients. In most of these patients, especially the ones diagnosed with FMF, the control of disease activity was maintained. The transition of these different clinical entities might require certain amendments to the standard of care. For future references, we will be able to understand more about the adulthood prognosis of these clinical entities.Disclosure of Interests:None declared
