“…ImageJ software (NIH) was used to measure and analyze electrocautery‐induced metal debris. Using previously developed techniques, 12,13 10 electron micrographs at the same magnification (x2.00k) per alloy were converted for size analysis (Figure 2) with a minimum debris diameter of 0.25 μm. Overlapping particles were removed using ImageJ analysis parameters or manually.…”

“…However, while the damage observed in this study is now thought to arise primarily from electrocautery effect, this study did show 51 to 69 components, or 74%, showing this form of damage. In a recent study of surgeon awareness of potential damage from electrocautery, 12 a survey showed that about 78% of surgeons when asked if they perform electrocautery on patients after the final components are implanted said they use electrocautery while only 38% stated that they use electrocautery during revision surgery while the implants are still placed. Also, when asked if a surgeon knew that electrocautery could induce damage, the result was that 49% said they were not aware.…”

Electrocautery‐induced molten metal particle generation from total joint replacements: Morphology and chemistry

Electrosurgical techniques are used during surgery to cauterize, and their damaging effects have primarily been documented in terms of tissue necrosis, charring, and localized heat accumulation. Metallic implants as well as the surgical blade can experience incidental electrosurgical current arcing that results in the generation and transfer of melted metallic particles. This work examines the composition, particle size distribution, and chemical state of the melted alloy surfaces and particles produced in vitro. Using scanning electron microscopy and energy dispersive spectroscopy, a flash‐melting particle generation phenomenon between source 304 SSL blades and polished cobalt‐chromium‐molybdenum (CoCrMo) and titanium‐6‐aluminum‐4‐vandaium (Ti6Al4V) surfaces was documented where 304 SSL mixed heterogeneously with the CoCrMo and Ti6Al4V ejecting “splatter” particles from the cautery site. The spherical micron‐sized particles were embedded with sub‐micron‐sized particles with 42% of the total sample population measuring between 0.25 and 0.35 μm in diameter. CoCrMo‐304 SSL particles were principally made of high concentrations of iron, oxygen, and nickel with embedded sub‐micron‐sized particles containing oxygen, chromium, and cobalt with lower concentrations of iron and molybdenum. Ti6Al4V‐304 SSL interactions resulted in similar micron‐sized particles made up of high concentrations of iron, nickel, and chromium with embedded sub‐micron‐sized particles containing titanium, oxygen, and small amounts of aluminum. X‐ray photoelectron spectroscopy of damaged CoCrMo surfaces confirmed the presence of chromium (VI) following dry electrocautery contact in coagulation mode. The structural effects of electrocautery‐induced damage are becoming visible in retrieval analysis, but the long‐term physiological implications during the lifetime of the implant from this damage mode have yet to be defined.

“…Miller et al [10] investigated the extent to which the electrocautery used during surgery damages the artificial heads and the effect of this damage on the UHMWPE inserts. Their measurements used a scanning electron microscope to detect pitting and minor surface damage and a profilometer to detect surface irregularities.…”

In our studies we analyzed the wear and damages of 15 explanted total knee implants. For this purpose, we first reviewed the relevant literature, which showed that most of the available articles are rather medical and do not contain relevant information from an engineering point of view, and those that are relevant from an engineering point of view are rather outdated from today's point of view. Therefore, we have developed an optical damage analysis that can be used to filter out results that are relevant and comparable from an engineering point of view. Our damage analysis was based on an existing and well-established method, which is now outdated and therefore, its further development was highly justified. The developed optical damage analysis was then used to test our samples. We drew conclusions, and based on these conclusions, we suggested how to improve further the systems we investigated.
