A veterinaryan stlye of life

After taking courses of external fixation in Nantes (France) and internal fixation in Barcelona and Davos (Switzerland), in the early 90′s I assume the responsibility of running the trauma unit at the Hospital Veterinari del Maresme at Mataró a referral center in the province of Barcelona. I was fascinated with the ability to heal the fracture respecting the specific biological pathway of bone healing.

In those days the pins we had available were Kirschner pins While you enter them appeared stable, however, the problems arise with the passage of days, problems such as pin loosening that contributed to fracture instability, delayed unions and non-union. This was much more frequent when applying a Type I frame (unilateral). To try to overcome these limitations I began to place the pins with an angle of 20° that prevent premature loosening.

A late 90′s I had in my hands the first threaded pins, they were of IMEX. While it showed a thread that improved fixation in the bone, this was very fine and also ended up failing. Shortly at AVEPA congress I was able to acquire positive threaded pins from an Italian company. It was my first positive threaded pins and…. worked: his performance was much better than the pins I had used before. But never again be able to acquire them. So I had it clear: we had to make our positive threaded pins and following the highest quality standards.

About the same time and following a course in human external fixation in the Hospital Clinic i Provincial in Barcelona, I was aware that while we had the best positive thread pins in my hands but did not have the best clamp. So we started to work. In late 2005 we funded Implantvet S.L. with the aim of developing a system of external fixation with the same principles as those used in external fixation systems for human application
After years of hard and exciting work we believe we succeeded.

Now is your turn to test it and evaluate it

The biomechanical properties of extrarius® clamp were assesed by Instituto de Biomecanica de Valencia.

All configurations tested show mean values of strength in the elastic limit higher than those reported by the other ESF commonly used in veterinary medicine in the anglosaxon countries (Kirschner-Ehmer and Securos).

Increasing from two to three fixations pins per bone fragment approximately double the axial compressive stiffness of bilateral Type II frame.

In a Type II frame the use of double bar approximately double the strength against axial compression, and failure occurred by plastic bending of the connecting bars and fixation pins.
