Failure mechanisms in CoCrMo modular femoral stems for revision total hip arthroplasty

et al. 2016

View full text Add to dashboard Cite

In this retrieval study, we reported the failure mechanisms of the CoCrMo-based hip implants. Systematic analyses on the clinically failed modular femoral stems from Revitan™ revision prostheses revealed a multistep fracture process. Multiple microcracks were first developed under the combined action of pitting corrosion and dynamic tensile stress on the lateral side of the CoCrMo connection taper. These microcracks then served as the initiation sites of further corrosion fatigue cracking leading to the final catastrophic failure. This crack initiation process has not been previously reported on retrieved CoCrMo components and our findings provide valuable information on the clinical performance of such implants, as well as the material selection and structural designs of future modular stems. © 2016 Wiley Periodicals, Inc.

“…Analysis of the literature indicates that main complications were and remain: osteolysis, instability of acetabular and femoral components, fracture of prostheses stems, increased wear of materials in a friction pair, the occurrence of debris, metallosis, dislocations of endoprostheses, complications associated with infections, with the use of bone cement and others [1][2][3]5,[8][9][10][13][14][15][16]19,21,23,25,[29][30][31][32]34,37,38,40,43].…”

This paper presents new design of total hip endoprosthesis, elements of whose were developed from the standpoint of system analysis and synthesis of biomechanical objects and devices. The main objective of this work is to increase the functional reliability of the endoprosthesis. The system approach was used in all stages of its development, including formulation of the problem and designing of manufacturing techniques.

“…Retrieval studies found that degradation of the stem results on the release of wear debris and metal ions, causing osteolysis and aseptic loosening of the implant . Thus, the synergistic effect of these mechanisms can be the central sources of in vivo corrosion of the materials, early fracture, inflammation of the surrounding tissues, and metal ion release for the host …”

In vitro Evaluation of Tribocorrosion Induced Failure Mechanisms at the Cell‐Metal Interface for the Hip Implant Application

et al. 2017

In a hip joint environment, the bone-metal implant interface of an implant is exposed to the combined effect of wear and corrosion (tribocorrosion). This may create mechanical instability and cause early failure of the implants. The aim of this work was to investigate the tribocorrosion behavior of Ti6Al4V alloys in the presence of bone-forming cells cultured on its surface (cell-metal interface), using an electrochemical and tribological approach. The results showed that at a cathodic potential (À0.9 V), the presence of osteoblast-like cells and serum proteins in the media might induce a higher passivation rate of the oxide film, enhancing the corrosion resistance. However, when the surface is in steady state (0.7 V) they show a lower resistant to corrosion, increasing the susceptibility to corrosion.
