This review summarizes the local circuit, interlaminar connections in adult mammalian neocortex. These were first demonstrated with anatomical techniques, which indicate some of the exquisite spatial precision present in the circuitry. Details, such as the class(es) of neurons targeted by some of these projections, have begun to be added in studies that combine paired/triple intracellular recor...

BACKGROUND Epidural steroid injections are commonly used for chronic spinal pain. However, there is no conclusive evidence regarding their effectiveness, and debate continues as to their value in managing chronic spinal pain. OBJECTIVE To evaluate various types of epidural injections (interlaminar, transforaminal, and caudal) for managing chronic spinal pain (axial and radicular). STUDY DES...

Exposing a laminate structure to thermal cycles and to temperatures close to the curing temperature, followed by mechanical fatigue, cause interlaminar and intralaminar cracks leading to degradation of the mechanical properties. The effect of thermal and mechanical fatigue, as well as thermal aging, on carbon fiber composite laminate structures is under study in the present paper.

ow back pain combined with radicular pain remains as one of the most challenging musculoskeletal problems for its therapeutic management (1). This malady results from nerve root impingement and/or inflammation that causes neurologic symptoms in the distribution of the affected nerve root(s). Conservative treatment, percutaneous spine interventions and surgery have all been used as treatments; a...

The Halifax interlaminar clamp is designed for posterior fixation of the cervical column. This technique has the advantages of being fast, safe, light and RM compatible. However the procedure is not useful when the laminae are fractured, not preventing either hyperextension or cervical rotation. We present our experience with the use of this technique in twelve patients who underwent posterior ...

Color and black and white line stimulation produce qualitatively and quantitatively different 2-deoxy[14C]glucose column patterns in the striate cortex of macaque monkeys. Microdensitometry of these stimulus-dependent columns reveals interlaminar density differences that serve as a signature for the stimulus conditions which produced them. Such columns are individually distinct and form a three...

There has been recent concern regarding the safety of cervical epidural steroid injections. The decision to proceed with treatment requires balancing the risk and benefits. This article is an in depth review of the efficacy, complications, and technique of both interlaminar and transforaminal cervical epidural steroid injections in the management of cervical radiculitis.

Pain Physician Vol. 9, No. 3, 2006 To the Editor: We report a case of intravascular uptake of contrast during interlaminar cervical epidural steroid injection (ESI) despite absence of spontaneous blood backflow through the needle hub and negative aspiration for blood. A 67-year-old female patient with neck pain and radiation of pain into her right shoulder and upper arm was referred to our pain...
