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.
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…

ICR in human cadaveric specimens: An essential parameter to consider in a new lumbar disc prosthesis design.
2020
[EN] Study design Biomechanical study in cadaveric specimens. Background The commercially available lumbar disc prostheses do not reproduce the intact disc's Instantaneous centre of Rotation (ICR), thus inducing an overload on adjacent anatomical structures, promoting secondary degeneration. Aim To examine biomechanical testing of cadaveric lumbar spine specimens in order to evaluate and define the ICR of intact lumbar discs. Material and Methods Twelve cold preserved fresh human cadaveric lumbosacral spine specimens were subjected to computerized tomography (CT), magnetic resonance imaging (MRI) and biomechanical testing. Kinematic studies were performed to analyse range of movements in or…
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…
Lifestyle Risk Factors Increase the Risk of Hospitalization for Sciatica: Findings of Four Prospective Cohort Studies
2017
BACKGROUND: The purpose of this study is to assess the effects of lifestyle risk factors on the risk of hospitalization for sciatica and to determine whether overweight or obesity modifies the effect of leisure-time physical activity on hospitalization for sciatica. METHODS: We included 4 Finnish prospective cohort studies (Health 2000 Survey, Mobile Clinic Survey, Helsinki Health Study, and Young Finns Study) consisting of 34,589 participants and 1259 hospitalizations for sciatica during 12 to 30 years of follow-up. Sciatica was based on hospital discharge register data. We conducted a random-effects individual participant data meta-analysis. RESULTS: After adjustment for confounding facto…
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…
Influence of Manual Therapies in Lumbar Disc Herniation A Case Study
2017
Magnetic Resonance Imaging (MRI) has so far been the best way to diagnose disc herniation, the high resolution of images taken on various vertebral tissues allowing the observation, in different planes, of situations such as: the displacement of dural sac and nerve roots, the disc hydration status, which are important data forthe diagnosis and prognosis of disc disease.Manual therapies mainly aim at restoring the lost joint mobility, but also the balance of muscular, skeletal and cranial systems. To this purpose, manipulationtechniques are used for decompression ofthe nerve root affected by disc herniation, spinal hypomobilityandnormalisation ofthe muscles that are peripheral to the lesion.…
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…
