Spinal Surgical and Spinal Research Fellowships

Perth, Western Australia, 1989 - 1991

Research Fellow in Spinal Injuries

With the financial assistance of the Postgraduate Bourse Neuromuscular Foundation of Western Australia Studentship, granted by professor B.A. Kakulas, dr. med. Guy spend a lot of his Perth time participating actively in fundamental research projects in the laboratories of professor B.A. Kakulas, MD, FRACP, FRCAP, FRCPath (Neuropathology and Neuromuscular pathology) and under further guidance of professor J.R. Taylor, MB, CHB, PhD, DMT (Spinal Anatomy and Human Biology), University of Western Australia.

Dr. Guy fully analyzed and documented 23,539 human postmortem spinal columns related to 13 spinal research projects. All fundamental scientific information was processed for Encyclopaedia lecturing and illustration. In 2004 all data were processed digitally in the laboratories of professor Hervé Deramond, father of vertebroplasty, Centre Hospitalier Universitaire, Amiens, France.

The spinal research projects concerned:

1.

Spinal metastatic carcinomatosis (PhD study):

Retrospective pathological evaluation of 2,081 spinal columns in patients who suffered different primary soft tissue carcinomas. Topics:

  • overall macroscopic and microscopic organic metastatic spread,
  • clinically & radiologically undetectable (microscopic) metastases,
  • overall vertebral metastatic spread,
  • intradural & extradural metastatic spinal cord compression,
  • clinicopathological correlations in oncological spinal cord compression,
  • effects of radiotherapy a/o chemotherapy,
  • development of ideas for innovative vertebral prosthesis (now already used in some Spinal Surgical Departments),
  • summary will be forwarded on www.guy-declerck.com/Spinal pathologies                        

2.

C2 odontoid:

Normal anatomy; nearly universal presence of the odontoideum; fracture patterns; anatomic analysis of the alar ligaments.

3.

Fatal odontoid fractures:

Pathological details not compatible with the classic Anderson and D’Alonzo classification (JBJS-1974-56A:1663).

4.

C3-C7 cervical spinal fractures:

Pathological fracture patterns in fatal spinal column injuries.

5.

Thoracolumbar fractures:

Pathological fracture patterns in 393 fatal thoracolumbar column injuries in relation to the radiological Denis classification (Spine, 1983, 8:817).

6.

Spinal cord:

Further evaluation of the long-term evolution of the spinal cord at different spinal levels in traumatic paraplegia and quadriplegia related to the published pathological study by Kakulas and Bedbrook in 1976:

Pathology of injuries of the vertebral column with emphasis on the macroscopical aspects’ by Kakulas BA, Bedbrook GM

In: Handbook of Clinical Neurology

Vinken PJ, Bruyn GW (eds)

Injuries of the spine and spinal cord

North Holland publishing Company, Amsterdam, 1976, Vol 25:27-42

7.

Paravertebral muscles:

Histochemical and electron microscopic evaluations of unusual spinal muscular morphological changes in patients suffering chronic degenerative discogenic syndrome in comparison to the paravertebral muscles of those not suffering low back pain.

The results are presented on www.guy-declerck.com/spinal pathologies.

8.

Intradiscal pressure measurements:

Non-standardized intradiscal measuring method in 2,452 lumbar intervertebral discs showed clear differences in pressure values in discs with and without complete degenerative annular tears.

9.

Effects of lifetime vibration frequencies on lumbar intervertebral discs

Pathological macroscopic analysis of lumbar vertebral endplates and annuli in discs subjected to physiological versus high professional industrial vibration frequencies.

10.

Spinal Osteoporosis

The information is the basis for an in depth  review of the world literature and is presented on www.guy-declerck.com/spinal pathologies.

11.

Lumbar degenerative discogenic disintegration

The scientific and illustrative data will be presented on www.guy-declerck.com/spinal pathologies.

12.

Lumbar zygoapophyseal facetal joints

Review of the international related literature on this controversial pathology is presented on www.guy-declerck.com/spinal pathologies.

13.

Whiplash syndrome

Abnormal and pathological intravertebral findings (tears in the different structures of the cervical intervertebral disc), invisible by modern investigational scanning, will be presented on www.guy-declerck.com/spinal pathologies.

Fellow in Adult Spinal Surgery

Dr. Guy was trained in all aspects of adult spinal surgery for a variety of spinal conditions including spinal metastatic disease by Mr. Philippe Hardcastle, FRCS, FRCAS, Spinal Orthopaedic Surgeon.

Clinical Assistant

In the Sir George Bedbrook Spinal Rehabilitation Unit, dr. Guy concentrated on all aspects regarding spinal rehabilitation of the paralysed patient. For the first time, he was confronted with treatments regarding ‘whole body vibration (WBV) with mechanically induced sinusoidal undulations in the prevention of osteopenia, muscle atrophy, and bedsores.

This experience now forms the basis for ongoing in vitro and in vivo research on whole body vibration for the healthy individual. The aim is to investigate further medical applications of the andullation frequencies being the combination of mechanically induced sinusoidal vibration frequencies (25-50 Hz) in association with an infrared warmth source.
