Cervical Spine Myelopathy and Radiculopathy

These terms are commonly used by spine surgeons to explain a medical condition where the spinal cord or the spinal nerves in the neck are not functioning properly.  These are Latin derived terms that need some explanation.

The cervical part of the spine is the neck.  The spine is comprised of vertebrae, spinal cord, spinal nerves and discs. The vertebrae are composed of bone. The spinal cord is a long bundle of nerve tissue serving as a major conduit for nerve impulses from the brain to the body.   The spinal cord represents the word “myelo”.   The term “pathy” means messed up, diseased, pathologic and improperly functioning.  Combined you get myelopathy.   The nerve roots branch out of the spinal cord.  When the nerve roots become a problem, it is given the term radiculopathy.  If the spinal cord and the spinal nerves are functioning abnormally, it is described as myeloradiculopathy.

This week I saw quite a few patients in my office that had cervical spine issues.  One patient, with an artificial disc implanted a few years ago still had significant pain in her neck.  On the front cover of The Spine Journal  issue of November 2012, appeared an ad about a cervical artificial disc  that provides Selectively Constrained Motion, an alternative to cervical spine fusion.  This particular patient had an artificial disc implant in her neck that was intact and functioning; continued to be in significant pain; was now using opiate narcotic pain medications daily to alleviate the pain.

With modern technology replacing a living and injured intervertebral disc in the neck with plastic and metal, how is it that this patient is still experiencing pain?  The possible answer may be that there is easy availability of strong pain medications or it could be an arthritic and degenerative condition that has developed in another part of the cervical spine.

This is a gentle reminder that spine surgery does not always solve every spine problem.   Spine surgery may be an option to enable you to function and feel better, but limit your expectations about spine surgery.  If you want perfection,  buy a Mercedes Benz.

Bearing surfaces for total disc arthroplasty: metal-on-metal versus metal-on-polyethylene and other biomaterials

Authors: S. Raymond Golish, MD, PhDa and Paul A. Anderson, MDb

BACKGROUND CONTEXT: Concerns about the effect of metallic wear debris from metal-on- metal bearing surfaces in total hip arthroplasty have increased. Some spinal arthroplasty devices include metal-on-metal bearing surfaces.

PURPOSE: To review the literature for clinical reports of complications because of wear debris from metal-on-metal spinal arthroplasty devices. To review the biology of wear debris from metal-on-metal bearing surfaces drawn from the hip arthroplasty literature and place it in the context of global regulatory actions and clinical and laboratory studies.

STUDY DESIGN: Literature review.

METHODS: To identify clinical reports, the PubMed database from the United States National Library of Medicine was queried using Medical Subject Headings terms and additional keyword terms. In addition, experts from academia and regulatory agencies were questioned regarding their knowledge of reports, including experts who attended the US Food and Drug Administration roundtable in September 2010.

RESULTS: Three case reports and one case series including seven total cases were identified in which abnormal inflammatory reactions and soft-tissue masses after metal-on-metal disc replace- ments were consistent with pseudotumor and metal hypersensitivity. Spinal cases are present as pain and neurologic symptoms. On plain radiography, there is no clear periprosthetic osteolysis or loosening. On magnetic resonance imaging, there is increased magnetic susceptibility artifact because of metallic debris that renders images inadequate. Computed tomography myelography demonstrates a soft-tissue mass, which exhibits epidural extension surgically. Histologically, large areas of necrotic debris and exudates are interspersed with chronic inflammatory cells. Lymphocyte or macrophage predominance is determined by the rate of wear and the presence of gross, micro- scopic, or submicron metallic wear debris. The metallurgy of the involved devices is cobalt- chromium-molybdenum (CoCrMo) alloy, and the bearing surface is CoCrMo-on-CoCrMo.

CONCLUSIONS: Metal-on-metal spinal arthroplasty devices are subject to postoperative compli- cations because of metallic wear debris with similar clinical, radiographic, histologic, gross anatomic, and device-related features to those found in metal-on-metal bearing surfaces in total hip arthroplasty.

David Campbell MDPA Media purchases AG-AF100

The Media Department at David Campbell MDPA has purchased a new video camera. After months of research and multiple camera auditions, the company has chosen the Panasonic AG-AF100. “The AF100 suits our needs perfectly because of its flexibility.” says Director of Media Jay Luka. “Our practice will use the camera for everything from patient testimonials, OR shooting to web based medical and patient educational videos. The interchangeable lens capabilities and large, DSLR like sensor were very attractive to us. The native AVCHD video codec is fantastic and produces beautiful, high quality video image. For a professional camera at this price point, the decision was really a no brainer.”
