INTRODUCTION We sought to document the efficacy of interlaminar epidural steroid injections (ESIs) for the relief of low back pain in a rural population. METHODS We conducted a prospective observational cohort study with brief follow-up telephone interviews at 1, 3 and 6 months after interlaminar ESI. RESULTS A total of 47 ESIs were administered to the 24 participants. In an intention-to-tr...

OBJECTIVES To describe how the anatomy of the cervicothoracic vertebrae predicates the appropriate fluoroscopic views for confirming safe needle placement during the performance of interlaminar cervical epidural injections. METHODS AND RESULTS Illustrations, cadaver models, and radiographic images were correlated and used to illustrate and derive a mathematical model to demonstrate the utilit...

Delamination is an important concern in the context of structural behaviour of laminated composite materials. It is known that delamination can diminish the stiffness and the strength of the material and promote structural failure. Delamination onset and growth is governed by interlaminar fracture toughness of the material. Delamination propagation is frequently dominated by mode II fracture; c...

Thermoelectric structural materials are potentially attractive for large-scale energy harvesting. Through filler incorporation and unprecedented decoupling of the bulk (laminae) and interfacial (interlaminar interfaces) contributions to the Seebeck voltage (through-thickness Seebeck voltage of a crossply continuous carbon fiber/epoxy composite laminate), this work provides thermoelectric power ...

We present here a rare case of heterotopic ossification in interspinous/interlaminar Coflex device. The classical surgical indications for these implants are degenerative canal stenosis, discogenic low back pain, disk herniations, facet syndrome, and instability. However, fractures of spinous processes are a potential risk after interspinous/interlaminar devices' implantation. Recently, heterot...

BACKGROUND Epidural injections have been used since 1901 in managing low back pain and sciatica. Spinal pain, disability, health, and economic impact continue to increase, despite numerous modalities of interventions available in managing chronic spinal pain. Thus far, systematic reviews performed to assess the efficacy of epidural injections in managing chronic spinal pain have yielded conflic...

In the present study, we quantified the distribution of growth cones and synapses in 2 developing layers, as well as in the intervening interlaminar space of the dorsal lateral geniculate nucleus (dLGN) in tree shrews. Our goal was to gain insight into mechanisms involved in the segregation of dLGN cells into layers during development. We sacrificed tree shrews before (P0), during (P4 and P7), ...

We explore how layered architectures influence the dynamics of stochastic neural field models. Our main focus is how the propagation of waves of neural activity in each layer is affected by interlaminar coupling. Synaptic connectivities within and between each layer are determined by integral kernels of an integrodifferential equation describing the temporal evolution of neural activity. Excita...

Interlaminar shear strength (ILSS) of fiber reinforced polymer composite is an important property for most of the structural applications. Matrix modification is an effective method used to improve the interlaminar shear strength of composite. In this paper, EPON 862/w epoxy system was modified using Tetraethyl orthosilicate (TEOS) electrospun nanofibers (ENFs) which were produced using electro...

Our objective was to assess the clinical outcome of interlaminar discectomy in patients suffering with degenerated lumbar disc lesions. We made a prospective study of 50 consecutive patients who underwent limited lumbar discectomy. The clinico-radiological parameters, type of surgery performed and the post-operative follow up were assessed. We found that interlaminar discectomy without laminoto...
