sysorb interference screw

Degradable Solutions is looking for distribution partners for our customer Sysorb GmbH.

sysorb® is a resorbable interference screw used for the tibial and femoral fixation (primary anchorage) of the autologous tendon grafts (or allograft) in the reconstruction of the cruciate ligament.

sysorb® has been widely used in more than 60,000 surgeries and documented in more than 40 publications. It has been demonstrated to be safe, efficient and easy to handle.

The patented turbine-like design of the bioresorbable interference screws, and of its mating screwdriver, allow easy and precise introduction and fixation of the implant. The blunt, atraumatic thread prevents laceration to the graft.

The sysorb® screw is made of the amorphous polymer poly-DL-lactide. It degrades fully within approximately one and a half years, leaving no crystalline remnants, unlike crystalline or semi-crystalline polymers.

The degradation kinetics of this polymer assures a strong fixation during the whole healing process.

sysorb’s main advantages are:

excellent biocompatibility of the non-crystalline implant material

unique patented drive adapted to the material and the function of the screw for higher precision during insertion

blunt threads to protect the tendon graft from laceration

the screw design is adapted to the material’s properties, preventing screw failure during insertion

fixation strength similar to that of metal screws

force transfer allows the insertion of the screw without pre-drilling and tapping – this results in an optimal compression of the neighbouring bone substance, leading to faster graft healing.
