Crevice Corrosion of Implants after TPLO
TPLO (Tibial Plateau Leveling Osteotomy) has become a standard surgery in dogs. A fascinating technique with good results, but are the implants that are used also satisfying? This study describes corrosion discovered on implants recovered from dogs after they underwent TPLO years ago. And it shows that the substances which are released during corrosion might cause disease. Very interesting!

4 dogs that had TPLO (n=7) 3 years earlier were included in this study.

Implants were recovered surgically and lightly cleaned before visual inspection, scanning electron microscopy (SEM) and energy-dispersive X-ray analysis (EDX).

Results: Multiple corrosion sites were found on the recesses of each plate; invariably, there was a corroded area present on that part of the bone screw which had been in contact with a corrosion site on a plate.

Most corroded regions featured attached, nonmetallic material believed to be a precipitate arising from interaction with the local environment during electrochemical corrosion. SEM examination of TPLO plates revealed surface porosity, particularly visible in the screw hole recesses.

Conclusions: Surface irregularities and porosity of TPLO plates—a consequence of the casting process—are initiation sites for corrosion which, in concert with the crevice geometry between the plate and screw, result in the observed corrosion defects.

Implants used for TPLO, a commonly performed veterinary orthopedic procedures may corrode generating a number of chemical species that have the potential to cause disease.

SMALL ANIMAL PRACTICE

Patient-specific facemask to facilitate brain biopsymembers
The objective of this pilot study was to describe the application and first preliminary data of a novel MRI and CT compatible patient-specific facemask for stereotactic brain biopsy of intracranial lesions in dogs. Five client-owned dogs presenting for neurological deficits consistent with forebrain disease were included in the study. All dogs had MRI findings consistent with an intracranial lesion. But biopsies in this region are not easy to obtain. Does an individual face mask help?
