Event Description

The literature article entitled ¿tribocorrosion in shoulder arthroplasty humeral component retrievals¿ by matthew g.Teeter, phd; michael j.Carroll, md, frcsc; gilles walch, md; and george s.Athwal; published in the journal of shoulder and elbow surgery, 2016, was reviewed.The article¿s purpose was to evaluate the presence of tribocorrosion in retrieved humeral total and hemiarthroplasty modular implants.We hypothesized that we would see mild or no corrosion or fretting damage at the modular connections of shoulder arthroplasty retrieval implants.There were 28 implants explanted, two were ap, depuy.The rest were competitors.Out of the two depuy ap implants, there was no evidence of corrosion on the connector, but one had mild fretting on both the head and stem sides this implant was explanted because of infection.The second one, was revised due to implant instability.The implant had mild corrosion on the head side of the connector but no corrosion on the stem side and had no visible signs of fretting on either connector side.
