HRC Locking Cage™
The HRC Locking Cage™ is a new concept for a spinal implant. Its self-locking mechanism with the titanium-blade allows excellent primary stability. Radiolucency is given by the PEEK Optima TL1 material. The anatomical, smooth shape of the implant secures easy and bone preserving using just one instrument. In clinical use since the beginning of 2001, its performance is confirmed. This concept is also available for lumbar spine treatment.
Cage made from PEEK-OPTIMA® material with a titanium blade for device stability
The unique design of the HRC Locking Cage™ product family comprising cervical, ALIF and PLIF implants offers the user an innovative concept for maintaining intervertebral spacing.
The load-bearing part of the cage consists of PEEK-Optima LT1, a poly-ether-ketone whose durability and flexibility are similar to those of the cortical bone, with the high level of biocompatibility needed for long-term implantation in the body. Moreover, the material is highly transparent to x-rays and does not generate radiographic distortions, thus permitting reliable positional verification of the implant. To allow for optimum intervertebral ossification, all HRC Locking Cages™ feature large openings that facilitate the filling with bone.
For easy placement the cages are contoured along smooth anatomical lines. The surface is free of serrations, minimising the risk of intraoperative fissuring.
To ensure the immediate device stability needed after placement, all cages are provided with a titanium alloy blade that prevents the cage from shifting. The special blade geometry permits stable anchoring with one simple rotation. Moreover, the force applied in the impacting process is distributed over the titanium blade, thus avoiding a weakening of the polymer. At the same time the blade serves as an x-ray marker.
The HRC Locking Cage™ product family has been used for lumbar vertebral fusions since 2000 and for cervical vertebral fusions since 2001.
Manufactured by EUROSPINE in Paris (France).
