VAOIS Shoulder System

Innovation in practice

Shoulder replacement has provided good clinical outcomes over the past 15 years. However, a number of challenges have been identified that can compromise the long term success of shoulder arthroplasty often requiring early revision of the prosthesis.

To overcome these well documented failure modes experts in the field of shoulder replacement surgery, biomechanical engineering and joint replacement design and manufacturing collaborated to develop a shoulder replacement system that is Versatile, Anatomic, Inverse Optimised and Stable (VAIOS) whilst utilising a minimum number of components and instrumentation.

VAIOS recieves best new product award

Back in 2010, we were delighted to hear that VAIOS had won the the best new (mechanical) product award at the British Engineering Excellence Awards.

It had only been possible because of an excellent collaboration between JRI, Professor Garth Johnson’s team at the University of Newcastle upon Tyne and Professor Angus Wallace in Nottingham.

As part of our commitment to introducing new products to the market in a safe and ethical manor, we are pleased to offer shoulder surgeons from around the world the ability to join and record their VAIOS Total Shoulder Replacement operations in a global VAIOS clinical audit. The registry enables surgeons and hospitals to record their VAIOS cases and follow up results (over and above existing national joint registries).

The data can then be analysed by JRI allowing us to monitor trends and highlight possible areas of improvement in the prosthesis. But more importantly, those contributing to the registry are able to benchmark their own results and compare with the groups (particularly useful for use in presentations and for audit purposes). Data gathered includes constant and Oxford scores at pre op, week 6, week 26, 1 year, 3 years and 5 years.

The registry, with the help of a surgeon adviser, is independently run by the Clinical Audit and Research Service based in the Tayside Orthopaedic and Rehabilitation Technology Centre, Ninewells Hospital and Medical School Dundee.

It is important to note that even though JRI are funding the registry, we have no access rights to modify or change any of the data and can only request reports to be compiled by the Clinical Audit Services Manager based based in the Tayside Orthopaedic and Rehabilitation Technology Centre.

To enter your VAIOS Inverse, Anatomic, Hemi Arthroplasty and Surface Replacement total shoulder replacements please contact Linda Johnston – Clinical Audit Services Manager at l.r.johnston@dundee.ac.uk or visit the registry input site.
