Early Onset of Guillain–Barré Syndrome Following Lumbar Disc Herniation Surgery: An Unexpected Clinical Evolution
2021
Letter: Guillain–Barré syndrome (GBS), is a neurologic complication rarely reported following a spinal surgery procedure.1, 2, 3, 4, 5, 6 GBS is a potentially fatal, immune-mediated disease of the peripheral nerves and nerve roots that is usually triggered by infections. It is the most common cause of acute flaccid paralysis, with an annual global incidence of approximately 1–2 per 100,000 person-years.7 Although the clinical presentation of the disease is heterogeneous, patients typically present with weakness and sensory signs in the legs that progress to the arms and cranial muscles. Disease progression can be rapid in approximately 20% of patients with respiratory failure requiring mech…
ADDISC lumbar disc prosthesis: Analytical and FEA testing of novel implants
2023
The intact intervertebral disc is a six-freedom degree elastic deformation structure with shock absorption. 'Ball-and-socket' TDR do not reproduce these properties inducing zygapophyseal joint overload. Elastomeric TDRs reproduce better normal disc kinematics, but repeated core deformation causes its degeneration. We aimed to create a new TDR (ADDISC) reproducing healthy disc features. We designed TDR, analyzed (Finite Element Analysis), and measured every 500,000 cycles for 10 million cycles of the flexion-extension, lateral bending, and axial rotation cyclic compression bench-testing. In the inlay case, we weighted it and measured its deformation. ADDISC has two semi-spherical articular s…
The efficacy of Ozone Therapy on different types of lumbar disc herniation : Proposal for guidance updates [abstract]
2018
Objective: To explore the possible mechanisms of pain relief by ozone therapy in patients with different types of lumbar intervertebral disc protrusion.
 Methods: The medical records of a total of 250 patients with protrusion of lumbar intervertebral disc (159 males, 91 females, aged 14–85 years) admitted in the South Hospital from January 2009 to June 2014 were retrospectively reviewed. Patients with protrusion of lumbar intervertebral disc were divided into four groups according to T2-weighted magnetic resonance imaging and digital subtraction angiography findings during ozone injection: type I, fibrous ring rupture without nucleus pulposus protrusion; type II, fibrous ring rupture w…
Effect of lumbar disc replacement on the height of the disc space and the geometry of the facet joints: a cadaver study.
2010
In a study on ten fresh human cadavers we examined the change in the height of the intervertebral disc space, the angle of lordosis and the geometry of the facet joints after insertion of intervertebral total disc replacements. SB III Charité prostheses were inserted at L3-4, L4-5, and L5-S1. The changes studied were measured using computer navigation sofware applied to CT scans before and after instrumentation. After disc replacement the mean lumbar disc height was doubled (p < 0.001). The mean angle of lordosis and the facet joint space increased by a statistically significant extent (p < 0.005 and p = 0.006, respectively). By contrast, the mean facet joint overlap was significantl…
Traumatic lumbar disc extrusion mimicking spinal epidural hematoma: Case report and literature review
2020
Background: Because the neurological presentation of spinal epidural hematomas (SEH) is often not specific, they may be misdiagnosed as acute lumbar disk herniations. Here, we present a case in which a traumatic disc extrusion mimicked an epidural hematoma and reviewed the appropriate literature. Case Description: A 27-year-old male sustained a high-energy fall. The lumbar MRI scan showed a L4-S1 ventral medium/high signal intensity mass on the T1- and high signal intensity lesion on T2-weighted images; the original diagnosis was spinal epidural hematoma. However, at surgery, consisting of a left L4 and L5 hemilaminectomy with L4-L5 and L5-S1 laminotomy, an extruded lumbar disc was encount…
Impact of selected magnetic fields on the therapeutic effect in patients with lumbar discopathy: A prospective, randomized, single-blinded, and place…
2018
Background. Interdisciplinary physical therapy together with pharmacological treatment constitute conservative treatment strategies related to low back pain (LBP). There is still a lack of high quality studies aimed at an objective evaluation of physiotherapeutic procedures according to their effectiveness in LBP. Objectives. The aim of this study is to carry out a prospective, randomized, single-blinded, and placebocontrolled clinical trial to evaluate the effectiveness of magnetic fields in discopathy-related LBP. Material and methods. A group of 177 patients was assessed for eligibility based on inclusion and exclusion criteria. In the end, 106 patients were randomly assigned into 5 comp…
Reoperations after first lumbar disc herniation surgery; a special interest on residives during a 5-year follow-up
2007
Abstract Background The overall rate of operations after recurrent lumbar disc herniation has been shown to be 3–11%. However, little is known about the rate of residives. Thus the aim of this study was to explore the cumulative rates of re-operations and especially residive disc herniations at the same side and level as the primary disc herniation after first lumbar disc herniation surgery and the factors that influence the risk of re-operations over a five year follow-up study. Methods 166 virgin lumbar disc herniation patients (mean age 42 years, 57% males) were studied. Data on patients' initial disc operations and type and timing of re-operations during the follow-up were collected fro…
Prevention of lumbar reherniation by the intraoperative use of a radiofrequency bipolar device: A case-control study.
2019
Objective: The most common complication after lumbar discectomy is reherniation. Although many studies have investigated factors that may increase the reherniation risk, few are agreed upon all. It has been suggested that limited nucleus removal is associated with higher reherniation risk, while more aggressive nucleus removal can result in increased disc degeneration. Here, we assessed the efficacy of a coblation-assisted microdiscectomy in adult patients undergoing single-level disc surgery. Methods: We prospectively compared the reherniation rate in 75 patients (Group 1) undergoing single-level lumbar disc surgery completed with the radiofrequency bipolar system Aquamantys® (Medtronic, M…
Red Flag for Cauda Equina Syndrome in Symptomatic Lumbar Disc Herniation
2020
Clinical follow-up after surgery of lumbar disc prolapses. A critical analysis.
1990
A retrospective clinical study was made on 987 patients with lumbar disc disease treated by discectomy. All patients had been operated on in the Department of Neurosurgery (University-Hospital Mainz). 545 patients were males, and 442 females (1.2:1). Patients in the 4th decade of life were affected most often (33.5%). Perioperative complications occurred in 5.4%, with discitis as the single major complication (1.9%). 83% of all patients who underwent discectomy could return to their normal occupation.
