Soft Tissue Internal Fixation

Vetlig: The Range


The material properties of ligaments designed for the various indications, correspond with the material properties of their native counterparts in regards to tensile strength. Each type of ligament contains a specific number and length of fibres depending on the intended use, and varying 'leaders' to facilitate passage through the bony tunnels. Some ligaments contain free-fibres and some do not, depending on their specific indication or the specific purpose or goal of the surgical intervention. Resistance to traction varies with the number of longitudinal fibres - approximately 3000N for 24 fibres to 6000N for 48 fibres. Vetlig have Achilles tendon, Patellar tendon, CCL and a woven mesh patch for soft tissue repair. The CCL comes in different sizes for pre and intra operative choice according to patient need.


Vetlig ligaments are intended for intra or extra-articular reconstruction; they can be used in conjunction with suturing to the remnant of the ruptured ligament, or as an autogenous reconstruction. In either case this allows the original ligament tissues to heal in the absence of traction and provides an earlier return to normal function. Vetlig can be used for extra-articular reconstructions in tendon repair, such as Achilles tendon, patellar tendon etc. These ligaments must always be placed in the joint in an anatomical or isometric position. The diameter of the bony tunnels must correspond to the specific reference for each type of ligament and as a general rule should be as small as possible. The fixation of the ligament extremities must always be extra-articular. Biological and mechanical testing on resistance, fatigue and creep has shown that Vetlig ligaments are highly effective ligament reconstruction and augmentation devices. The use of the Vetlig artificial ligament requires a specific surgical technique, for which dedicated instruments are available.


Vetlig CCL is selected depending on the weight of the dog.

24 fibres 10-15kg, 32 fibres 15-25kg, 48 fibres over 25kg. If a small dog is very active i.e. fly ball or a working dog, then choose the next size up.

It is anchored into femoral and tibial bone tunnels by titanium interference screws. The strength of the ligament is over 3000-6000 newtons for all sizes. Or you can use a suspensory button technique.

Achilles and Patellar

The Achilles tendon repair comes in one size, which can be cut to length between the blue markers for different breeds of dogs. It is a good option for chronic or acute Achilles injuries. It is sutured proximally with non-resorbable sutures and anchored in the calcaneum with an interference screw. You can also use this implant for patellar repair. Use one or two ligaments depending on the size of the dog, suture the flat portion of each implant over the patellar and into the quads, and then pull the implants and the patellar distally before securing them to the tibia with an interference screw.

Large Soft Tissue Patch

A woven flat band, sutured with non-resorbable sutures for many different types of soft tissue repair.

This can be used for humeral and hernia repair and also for felines.

Hip Subluxation

Hip Subluxation patch, suture with non resorbable sutures onto  gluteal tendon or abductor muscle, anchor in with a screw into a trans-osseous tunnel.

Large Tendon Repair

330mm x 7mm suture or screw fixation as required, can be cut to length.

Collateral Ligament

Can be screwed or sutured in place for large ligament defects, adaptable to size.

Small Tendon Repair

50mm x 4mm Suture in place, it can be cut if required.


Titanium screws are introduced over a 1mm guide wire and tightened with a Vetlig specific screwdriver. All applications use these screws as they work specifically with the ligament so they don’t cut the fibres and fit flush in the tunnel.
