Professor of the John Scales Centre for Biomedical Engineering at the Institute of Orthopaedics & Musculoskeletal Science (IOMS) at Stanmore.
Corrosion of hip replacements – Is it a problem?
Recently it has been shown that failure of hip replacements is related to corrosion at the modular junctions. This corrosion results in the release of metal ions causing adverse reactions such as pain and the development of pseudotumours; these will require the hip to be revised.
Corrosion at the trunion interface has been identified and measured in retrievals and has been replicated in in-vitro tests.
These tests show that the main variables are;
- The surface finish of the tapers
- Galvanic corrosion associated with the use of mixed alloys
- The position of the implant, which will increase bending moments and torque on the trunion interface
- And most importantly the way the surgeon fits both interfaces together
Methods to reduce taper corrosion have been examined and have been successful.
