A strong synthetic ligament and a knot-free technique ligament

Traumatic dislocation of the hip often requires surgical management. Reconstruction of the round ligament has shown a higher average success rate compared to other techniques.

NOVALIG®-PLATINE allows for intra-articular reconstruction of the round ligament and simple, immediate and reliable acetabular fixation using a cortical button. This technique completely eliminates the need for a knot, replaced by solid bone anchoring using an interference screw.

What type of postoperative immobilization is recommended?

In case of intra articular reconstruction of the round ligament with NOVALIG, the dog can bear weight on his limb as soon as he wakes up. No immobilization is applied in the immediate postoperative period. Strict rest is recommended for the first six weeks.

What is the advantage of not using knots to fix the implant in the event of hip dislocation?

Knots have varying strength from one surgery/surgeon to the other.

They also take up a certain volume, often close to the surgical approach, which may cause irritation and inflammation, or create a bridge for infection.

The use of an interference screw embedded in a bone tunnel offers the considerable advantage of keeping the synthetic material away from the skin and providing superior mechanical strength.

NOVALIG® is described as a synthetic ligament - but how is it different from a suture?

NOVALIG® is much stronger and wider than a suture. Its theoretical strength can reach 8000N.

Its special braiding makes it much less abrasive and sharp than FiberTech-type UHMWPE sutures, thus limiting bone shearing effects. It also has a favorable interface for cell colonization.

The NOVALIG® ligament is relatively long, which makes multi-ligament repair possible with a single ligament and several bone anchors.

Why use interference screws for fixation?

Interference screws provide immediate, atraumatic fixation for the implant and are fully fixed in the bone. They reduce the risks of irritation and early laceration thanks to a large knot.

The mechanical resistance of this type of fixation has made it a gold standard in many human medicine applications.
