  • Department of Ortho and MSK Science
  • Div of Surgery & Interventional Sci

Stephen JG Taylor received his BSc in Electrical and Electronic Engineering from the University of Bath in 1979. He worked in electrical instrument development for 2 years before entering the field of medical telemetry. He gained his MSc in Medical Electronics and Physics in 1983 from the University of London. After a further period in industrial instrumentation he became Senior Research Fellow at UCL Institute of Orthopaedics and Musculoskeletal Science, Stanmore. He gained his PhD in 1998 at UCL, and became a Lecturer in Biomedical Engineering at the Institute of Orthopaedics and Musculoskeletal Science (IOMS), UCL in 2004. In October 2015 he became a Reader in Musculoskeletal Instrumentation and Telemetry. He has developed several instrumented orthopaedic implants, associated telemetry systems and calibration rigs for measuring dynamic joint forces in vivo, and conducted clinical trials to study implant loosening and isometric implant forces. He designed a novel magnetic drive system for the UCL extendible prosthesis for non-invasive bone tumour paediatric limb lengthening, now implanted in several hundred children worldwide. He is Course Tutor for the iBSc in Orthopaedic Science at IOMS. He is author or co-author of ~30 journal articles. His research interests are implantable telemetry for force measurement, fracture healing, in vivo electromyography, implant fixation, and model validation; in vivo measurement for prosthetic control; remote monitoring for wheelchair user accessibility; electronic packaging.

Research Summary

Measurement of forces acting on orthopaedic implants in vivo:
Development work on modified bone tumour, shoulder and tibial nail implants has led to instrumented versions of these implants for measuring the forces acting across the implants in selected subjects in vivo during activity. These implants are powered and interrogated by magnetic induction. Measured in vivo data from four volunteer subjects were used to assess implant loosening, study the biomechanics of load transfer across joints, provide forces to inform rehabilitation regimes, provide data for validating mathematical models, and for implant testing machines.

Currently instrumented implants in development are the reverse-anatomy shoulder prosthesis for rotator cuff arthropathy, a separate compartment tibial tray, and several generations of a tibial nail. The first instrumented glenoid replacement was implanted in Jan 2009. Other joints of interest are the ankle and the elbow.

Remotely extendible implants: development of drive unit for the Stanmore extendible femoral growing prosthesis for children with bone tumours. PhD project supervision for spinal implant lengthening for scoliosis patients. These projects involve magnetic coupling for transfer of power into the implant for extension.

Sensewheel: a lightweight instrumented wheelchair wheel which measures pushrim forces and telemeters them to a laptop, tablet or mobile phone. Application to wheelchair user mobility and propulsion efficiency; related to shoulder pain.
