ITAP on the BBC

9 April 2014

Intra Osseous Transcutaneous Prostheses (ITAP) was invented at the UCL Institute of Orthopaedics & Musculoskeletal Science by Gordon Blunn, Professor of Biomedical Engineering, and Dr Catherine Pendegrass, Senior Lecturer in Biomedical Engineering.


This involves the attachment of an external prosthetic device directly to the bone using an implant that passes through the skin barrier. The main advantage of ITAP is that it directly loads the bone and amputees do not have to use a stump socket attachment, which can result in discomfort.  The use of stump socket devices sometimes leads to so much pain and instability, which makes the external prosthetic device difficult to use. This procedure was pioneered by surgeons at the Royal National Orthopaedic Hospital in Stanmore where a clinical trial  investigating the use of ITAP for trans-femoral amputees is underway.
