Later publications have been in the clinical practice of spinal surgery and spinal biomechanics. A particular interest has been the spinal intervertebral disc and its degenerative changes with age and injury which led to me setting up a biomechanical research laboratory using cadaveric and artificial spine models. This resulted in several publications upon stresses in intervertebral discs and to the development of a novel design for a spinal intervertebral disc replacement. I have had a lifelong interest in hands-on teaching of other surgeons, demonstrating the operative approaches to the spine at cadaveric workshops both nationally and internationally.
