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 STIF 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 1500N for 30 fibres to 2500N for 60 fibres. Vetlig have Achilles 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.


STIF currently comes in three intra-articular sizes, 15mm free fibres, 17mm free fibres 19mm free fibres.

The woven part of the fabric which is the tensile strength comes in 30, 44 and 60 fibres and corresponds to the size of the dog.

It is then anchored into femoral and tibial bone tunnels by titanium interference screws. The strength of the STIF is over 1500-2500 newtons for all sizes.





The Achilles tendon repair comes in one size, which can be cut to length for different breeds of dogs. It is a good option for chronic Achilles injuries. It is sutured proximally with non-resorbable sutures and anchored in the calcaneum 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.








Patellar Repair

Suture to fibrous patellar tissue and anchor into the tibia with a screw. Adaptable for medial or lateral patellar slipping.








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.










The screw is guided in over the hexagonal guide wire, which fits in the cannulated screwdriver.









STIF ligaments are intended for intra or extra-articular reconstruction. STIF can be used in conjunction with suturing to the remnant of the ruptured ligament, or as an autogenous reconstruction. In both cases STIF allows the original ligament tissues to heal in the absence of traction and provides an earlier return to normal function. STIF can be used for extra-articular reconstructions in tendon repair, such as Achilles tendon, patella 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 STIF ligaments are highly effective ligament reconstruction and augmentation devices. The use of the STIF artificial ligament requires a specific surgical technique, for which dedicated STIF instruments are available.
