Intro Biosurgex

Our expertise originates from a long experience in studying challenging bone and joint conditions and looking for the most suitable tailored solutions to treat them.

We have learned a lot over the years, but there are two notions we love to stick to.

To start with, every clinical case is unique because every patient is unique. As far as we can, we will provide veterinary surgeons with the most specific solution for your pet.

Additionally, living creatures have outstanding self-healing capabilities. We will always choose less invasive, tissue sparing surgical solutions, provided that such solutions are safe and effective.


Tibial Tuberosity Advancement. Porous TTA.

Tibial Tuberosity Advancement (TTA) is one of the most common, effective and safe surgical procedures to treat cranial cruciate ligament deficiencies in dogs. Cranial cruciate ligament deficiencies lead to abnormal craniocaudal translation of the tibia and excessive internal rotation of the stifle joint, which, over time, can cause osteoarthritis. In TTA the tibial tuberosity is advanced cranially through an osteotomy in the frontal plane and the insertion of a wedge. The resulting advancement of the patellar tendon neutralizes the cranial tibial thrust, thus stabilizing the stifle joint during weight-bearing.

The biosurgex solution includes a porous titanium TTA wedge which promotes fracture healing through complete osteointegration. The biosurgex porous titanium TTA solution has been implanted in approximately 10,000 cranial cruciate ligament deficiency cases since 2011.

• Optimized pore geometry for faster, better bone ingrowth.
• Easy, accurate, safe surgical technique.
• Support available for surgical planning.


Polyaxial locking plate system.

Over the years, osteosynthesis has evolved from a purely anatomical reconstruction to a biology driven axis restoration approach. Locking plates work on the same principles as external fixators, acting as bridging systems between fracture fragments. Contact between plate and bone is, therefore, unnecessary and the increased vascular supply promotes bone union and resistance to infection.

Our titanium polyaxial locking plates feature a unique mechanism which aligns the screw and hole threads providing more flexibility and safety during the surgical procedure.


• can be bent.
• improved biocompatibility of metal and surface oxides, superior corrosion resistance, lower stiffness, enhanced diagnostic imaging properties as compared to stainless steel.

Bridge plating philosophy:
• allows Minimal Invasive Percutaneous Osteosynthesis (MIPO).

Unique thread alignment mechanism:
• keeps plate hole threading always aligned to screw threading allowing easier and safer multiple threading/unthreading.

Polyaxial locking screws (± 15°):
Non-aligned holes:
• increased torsional resistance.

Torx screw head:
• higher maximum torque as compared to hex head.

Long bone diaphyseal defects.

Treatment of large diaphyseal bone defects has always been a difficult clinical challenge. A defect longer than twice the diameter of the diaphysis is generally critical, as bone is unlikely to heal if the gap is left unfilled.

Fixation can be then associated with autogenous bone grafting, allografts, synthetic grafts or metal scaffolds. Using autogenous bone grafts implies a longer procedure and a second surgical site with increased patient morbidity risk. A suitable augment should have the mechanical properties needed for optimal scaffolding, be osteoconductive and, ideally, osteoinductive.

Our solution includes a porous titanium augment and a polyaxial locking bridge plate. The augment has mechanical properties similar to bone, fully interconnected pores, which allow for bone ingrowth and neovascularization, and can be loaded with osteogenic agents.

• Limb salvage solution.
• Titanium locking plate ensures primary stability and immediate function recovery.
• Porous titanium augment ensures long-term secondary stability.
• Plates can be connected to augments with wires (cerclage) or cortical screws.
• Augments available in 5 diameters, 10 lengths for each diameter.


canine distal radius osteosarcoma.

Osteosarcoma is by far the most common bone tumor in dogs. More than 75% of the osteosarcoma cases are appendicular, with distal radius being the predilected primary site. Limb sparing surgical treatment of canine distal radius osteosarcoma is becoming increasingly popular because of owner preference and survival rates comparable to amputation when post-operative chemotherapy is administered.
The biosurgex limb sparing distal radio osteosarcoma system is composed of a bendable titanium plate, which ensures anatomical fit, primary stability and immediate function recovery and a porous titanium spacer, which caters for long-term secondary stability.

• Limb salvage.
• Porous titanium augment ensures long-term secondary stability.
• Bendable titanium plate ensures anatomical fit, primary stability and immediate function recovery.
• Curved plate profile to match augment shape.
• Plate connected to augment with cortical screws.
• Augments available in 9 sizes, plates available in 4 sizes.


cervical spondylomyelopathy.

Cervical spondylomyelopathy (CSM), or wobbler syndrome, is a relatively common disease in large and giant breed dogs. It most often affects young giant breed dogs with a congenital bone compression induced narrowing of the spinal canal or vertebral malarticulation (bone-associated wobbler syndrome) or middle-aged large breed dogs with a congenital spinal canal stenosis causing subsequent degenerative changes of the intervertebral disc and surrounding soft tissues (disc-associated wobbler syndrome).

When surgical treatment is indicated, the biosurgex solution is a porous titanium distraction-fusion spacer stabilized with a dedicated fixation plate. Porous titanium geometric and mechanical characteristics closely resemble those of bone, promoting bone ingrowth and stable vertebral fusion.

• Combined distraction and stabilization.
• Porous titanium spacer ensures stability and promotes vertebral fusion.
• Avoids autologous bone harvesting.


costume-made solutions.

Every patient is unique and every clinical case has its own distinctive features. When standardized solutions cannot guarantee optimal treatment, biosurgex can help identify, design and manufacture a custom-made solution for each patient.

A 3D model of the patient’s anatomy is obtained from a CT scan. The 3D model allows to define an individualized surgical plan and design customized implants and instruments. Surgical planning and implant and instrument design are carried out in collaboration with the veterinary surgeon.

• Products backed by long history in custom solution design and manufacturing.
• Implant is made to fit anatomy, rather than anatomy is changed to fit implant.
• Easier and safer surgical procedures.


About Biosurgex

About Us

biosurgex is the veterinary medicine division of osteobionix, a company founded in 2018 as a spin-off of the Canary Islands Institute of Technology (ITC – Instituto Tecnológico de Canarias). We are proud to provide cutting-edge, highquality, off-the-shelf and customized solutions for veterinary orthopaedic and trauma surgery.

The ITC Department of Biomedical Engineering has worked on innovative solutions for bone and cartilage deficiencies since 2006. The first custom porous metal implant designed and manufactured by ITC was implanted in 2011. Since then, the team has worked successfully with international veterinary and human orthopaedic surgeons to solve complex problems with innovative solutions. The ITC Department of Biomedical Engineering team is now working for biosurgex to support the patients and surgeons communities worldwide.
