Quality of life changes after lumbar decompression in patients with tandem spinal stenosis

Objective Tandem spinal stenosis (TSS) is a degenerative spinal condition characterized by spinal canal narrowing at 2 or more distinct spinal levels. It is an aging-related condition that is likely to increase as the population ages, but which remains poorly described in the literature. Here we sought to determine the impact of primary lumbar decompression on quality-of-life (QOL) outcomes in patients with symptomatic TSS. Patients and methods We retrospectively reviewed 803 patients with clinical and radiographic evidence of TSS treated between 2008 and 2014 with a minimum 2-year follow-up. The records of patients with clinical and radiographic evidence of concurrent cervical and lumbar stenosis were reviewed. Prospectively gathered QOL data, including the Pain Disability Questionnaire (PDQ), Patient Health Questionnaire-9 (PHQ-9), EuroQOL-5 Dimensions (EQ-5D), and Visual Analogue Scale (VAS) for low back pain, were assessed at the 6-month, 1-year, and 2-year follow-ups. Results Of 803 identified patients (mean age 66.2 years; 46.9% male), 19.6% underwent lumbar decompression only, 14.1% underwent cervical + lumbar decompression, and 66.4% underwent conservative management only. Baseline VAS scores were similar across all groups, but patients undergoing conservative management had better baseline QOL scores on all other measures. Both surgical cohorts experienced significant improvements in the VAS, PDQ, and EQ-5D at all time points; patients in the cervical + lumbar cohort also had significant improvement in the PHQ-9. Conservatively managed patients showed no significant improvement in QOL scores at any follow-up interval. Conclusion Lumbar decompression with or without cervical decompression improves low back pain and QOL outcomes in patients with TSS. The decision to prioritize lumbar decompression is therefore unlikely to adversely affect long-term quality-of-life improvements

Estenose Espinhal de Tríplice Região Sintomática (EETRS): relato de um caso e revisão narrativa da literatura

IntroductionSimultaneous spinal stenosis in three regions of the spine is an unusual condition that demands proper clinical evaluation and imaging. Currently, there are no established guidelines for its diagnostic and therapeutic approach. The objective of this study is to describe, based on a case report, the clinical presentation, treatment, and patient progression concerning triple stenosis, contrasting it with available evidence through a narrative review of the literature.

A RARE CASE OF SUCCESSFUL STAGED SURGERY IN THE PATIENT WITH JOINED STENOSIS OF THE VERTEBRAL CANAL AT THE CERVICAL, THORACIC AND LUMBAR LEVELS

In the present article we describe a clinical example of a successful staged surgical treatment in the patient with rare joined stenosis of the vertebral canal at the cervical, thoracic and lumbar levels, surgical rehabilitation was 24 weeks. In connection with clinical data the first stage included ventral decompression of the cervical department of the spinal cord and spondylodesis by a telescopic prosthesis of a vertebral body, during the second stage through a minithoracotomy with an endovideo-assistance we performed anterolateral decompression of the spinal cord and spondylodesis by a telescopic prosthesis of a vertebral body with a lateral plate, and the third stage consisted of dorsal decompression of a dural bag and roots of the spinal cord, transpedicular fixation with an interbody spondylodesis in a lumbar department of the spine. Applying low-traumatic techniques for decompression and spondylodesis with specialized devices we could decrease level of pain syndrome, degree of neurologic deficiency, improve life quality and carry out effective fixation of three operated on vertebral aspects. Mini-invasive staged microsurgical decompressive stabilizing techniques can be used for successful treatment in patients with joined stenoses in the vertebral canal and also allow to reduce considerable risks for life and to cause full rehabilitation in the shortest possible time

Spine Surgery

We are very excited to introduce this new book on spinal surgery, which follows the curriculum of the EUROSPINE basic and advanced diploma courses. The approach we take is a purely case-based one, in which each case illustrates the concepts surrounding the treatment of a given pathology, including the uncertainties and problems in decision-making. The readers will notice that in many instances a lack of evidence for a given treatment exists. So decisions taken are usually not a clearcut matter of black or white, but merely different shades of gray. Probably in a lot of cases, there is often more than one option to treat the patient. The authors were asked to convey this message to the reader, giving him a guidance as what would be accepted within the mainstream. In addition, the reader is provided with the most updated literature and evidence on the topic. Most of the authors are teachers in the courses of EUROSPINE or other national societies with often vast clinical experience and have given their own perspective and reasoning. We believe that the readers will profit very much from this variety and bandwidth of knowledge provided for them in the individual chapters. We have given the authors extensive liberty as to what they consider the best solution for their case. It is thus a representative picture of what is considered standard of care for spine pathologies in Europe. We hope that this book will be an ideal complement for trainees to the courses they take.

Next generation of growth-sparing techniques: preliminary clinical results of a magnetically controlled growing rod in 14 patients

Session 3A - Early Onset Scoliosis: Paper no. 33SUMMARY: Growth-sparing techniques are commonly used for the treatment of progressive EOS. The standard growing rod (GR) technique requires multiple surgeries for lengthening. The preliminary results of MCGR has shown the comparable outcomes to standard GR without the need for repeated surgery which can be expected to reduce the overall complication rate in GR surgery. INTRODUCTION: The growing rod (GR) technique for management of progressive Early-Onset Scoliosis (EOS) is a viable alternative but with a high complication rate attributed to frequent surgical lengthenings. The safety and efficacy of a non-invasive Magnetically Controlled Growing Rod (MCGR) has been previously reported in a porcine model. We are reporting the preliminary results of this technique in EOS. METHODS: Retrospective review of prospectively collected multi-center data. Only patients who underwent MCGR surgery and at least 3 subsequent spinal distractions were included in this preliminary review. Distractions were performed in clinic without anesthesia or analgesics. T1-T12 and T1-S1 height and the distraction distance inside the actuator were analyzed in addition to conventional clinical and radiographic data. RESULTS: Patients (N=14; 7 F and 7 M) had a mean age of 8y+10m (3y+6m to 12y+7m) and underwent a total of 14 index surgeries (SR: index single rod in 5 and DR: dual rod in 9) and 91 distractions. There were 5 idiopathic, 4 neuromuscular, 2 congenital, 2 syndromic and one NF. Mean follow-up (FU) was 10 months (5.8-18.2). Mean Cobb changed from 57° pre-op to 35° post-op and correction was maintained (35°) at latest FU. T1-T12 increased by 4 mm for SR and 10 mm for DR with mean monthly gain of 0.5 and 1.39, respectively. T1-S1 gain was 4 mm for SR and 17 mm for DR with mean monthly gain of 0.5 mm for SR and 2.35 mm for DR. The mean interval between index surgery and the first distraction was 66 days and thereafter was 43 days. Complications included one superficial infection in (SR), one prominent implant (DR) and minimal loss of initial distraction in three after index MCGR (all SR). Overall, partial loss of distraction was observed following 14 of the 91 distractions (one DR and 13 SR). This loss was regained in subsequent distractions. There was no neurologic deficit or implant failure. CONCLUSION: MCGR appears to be safe and provided adequate distraction similar to the standard GR technique without the need for repeated surgeries. DR patients had better initial curve correction and greater spinal height. No major complications were observed during the short follow-up period. The FDA has not cleared the drug and/or medical device for the use described in this presentation (i.e., the drug or medical device is being discussed for an ‘off label’ use).postprin

Noninvasive intracranial pressure profile in 31 patients submitted to fullendoscopic spine surgery

ABSTRACT Purpose: Full-endoscopic spine surgery (FESS) is associated with specific complications, possibly linked to increased intracranial pressure (ICP) resulting from continuous saline infusion into the epidural space. This study aimed to assess the impact of saline irrigation and its correlation with noninvasively obtained ICP waveform changes. Methods: Patients undergoing FESS between January 2019 and November 2020 were included. Noninvasive ICP (n-ICP) monitoring utilized an extracranial strain sensor generating ICP waveforms, from which parameters P2/P1 ratio and time to peak (TTP) values were derived and correlated to irrigation and vital parameters. Documentation occurred at specific surgical intervals (M0–preoperatively; M1 to M4–intraoperatively; M5–postoperatively). Mixed-model analysis of variance and multiple comparisons tests were applied, with M0 as the baseline. Results: Among 31 enrolled patients, three experienced headaches unrelated to increased ICP at M5. The P2/P1 ratio and TTP decreased during surgery (p < 0.001 and p < 0.004, respectively). Compared to baseline, P2/P1 ratio and vital parameters remained significantly lower at M5. No significant differences were observed for fluid parameters throughout surgery. Conclusions: This study demonstrated a decline in the n-ICP parameters after anesthetic induction despite the anticipated increase in ICP due to constant epidural irrigation. The n-ICP parameters behaved independently of fluid parameters, suggesting a potential protective effect of anesthesia

Idiopathic Intracranial Hypertension: Epidemiology, pathophysiology, clinical features and contemporary management.

Idiopathic Intracranial Hypertension (IIH) is a syndrome of increased intracranial pressure (ICP) without evident cause. The exact pathogenesis of IIH remains elusive but it is also plausible that the syndrome represents the common final pathway of several different mechanisms. IIH has an estimated incidence of 1-3 per 100 000 and a predilection for obese women of childbearing age.  Presentation involves symptomatology and semiology of elevated intracranial pressure with headache being the most common. Visual disturbances can be devastating, progressive and may result in permanent visual loss. Moreover, pulsatile tinnitus is frequently encountered. However, asymptomatic presentations are also not uncommon with patients diagnosed after routine ophthalmological examination illustrates papilledema. Diagnosis is based upon the Friedman’s criteria. Absence of hydrocephalus or mass lesion and normal cerebrospinal fluid (CSF) composition need to be confirmed. Several treatment modalities have been suggested, varying from non-surgical (weight loss, drugs such as acetazolamide, serial lumbar puncture) to interventional and surgical (CSF diversion procedures, optic nerve sheath fenestration (ONSF), endovascular venous sinus stenting, or even bariatric surgery). There are very few RCTs to critically assess these therapies and, consequently, no consensus on the optimal management of IIH.
