Additive manufacturing (AM) offers a few major benefits to biomedical applications. To improve the knowledge on AM possibilities, Sirris is organizing two different masterclasses. The first will address the technology, materials used and applications, with experts in the matter explaining all relevant aspects.

1. Masterclass:
Biomedical applications of
Additive Manufacturing
Practical case study 3: Veterinary case studies –
successful AM manufactured bone replacements

2.  AIMME’s mission
 AIMME’s biomedical activities
 Veterinary case studies
• Case of « Argos »
• Case of « Fito »
• Case of « Baby »
 Including a short video

4. AIMME’s biomedical activities
Based on extensive expertise and know how with additive technologies, in
particular metal processing ALM
Consists in:
• development of new materials to be processed on existing systems
• improvement of technology for improved biomedical performance
• development of new ideas and concepts for high value added medical devices
• development of new bussiness models for medical device supply chain
• technical advice and DFM for ALM technologies

7. 1. Case of “Argos”
Argos is an 8-month Bordeaux Mastiff of 50kg. He was diagnosed a bilateral hip
dysplasia with grade I patella luxation in the right knee.

8. 1. Case of “Argos”
Initially, the surgeon
performed a triple
pelvis osteotomy on
the right side using a
standard commercial
plate.
Only 3 days after the
surgical intervention,
during the first
control, a loosening
of fixation screws was
detected.

9. 1. Case of “Argos”
The proposed
measure was to
increase the size of
the screws from M3.5
to M4.5.

10. 1. Case of “Argos”
In order to prevent risks of screw loosening, the surgeon sought for a more feasible
solution for the left hip side - a customized plate made on EBM

11. 1. Case of “Argos”
As expected, the
revision revealed
that the screws on
the right hip
(commercial plate)
started to migrate
again
while the screws
on the left hip
customized plate)
stood as tight as
after the
intervention.

12. 2. Case of “Fito”
Fito:
- German sheppard
- 4-years old
- 40kg.
He was hit by a car
and suffered
a multiple diaphysal
fracture with big
bone splinters.

13. 2. Case of “Fito”
• The bone fracture was repaired with a
standard titanium plate and 12 screws of
M3.5.
• During the intervention, the surgeon
noticed that the plate had to be
modified by hand to fit the damaged
zone.
• Surgeon was modeling the plate with a pair
of surgical pliers, and verifying visually that
the plate was fitting properly.

14. 2. Case of “Fito”
• The drawback appeared after only 3
days.
• Fito started to limp severely.
• An angular deformation in the
femoral zone was detected.
• The plate suffered a fracture and
completely lost its functionality.

16. 2. Case of “Fito”
• The operation was successful.
• According to the last news Fito
has a normal functionality in the
injured leg.
• Unfortunately, postoperatory
images were never received.

17. 3. Case of “Baby”
• Baby is a 3-year old Yorkshire Terrier.
• Abandoned and found by pro-animal activists in a difficult health conditions.
• Admitted in December 2009 presenting a radius-cubital diaphysal oblicuous
fracture with severe loss of radiographic density due to osteoporosis and
disuse of the leg in question.
• Approx. 20-25% of radius-cubital length had been lost.
• A challenging experimental case with few chances of success
• No commercially available plate of this size and capable of being
adapted to the damaged zone
• The surgeon and CIMA researchers decided to design a customized
titanium plate.
