      Carving Round Lumbar Interbody Fusion

      The first LfC’s 3D-Frame-Ti implant was the CarЯLIF (Carving Round Lumbar Interbody Fusion) – it is the first 3D printed, curved spinal cage worldwide. The clinical implantation started in the year 2011.

      This cage combines the fusion enhancing features of the 3D-Truss-Ti structure together with the precision of insertion and placement provided by the unique “carving guides”. It is still the “flagship” implant of the whole CarЯLIF-family – a group of implants based on 3D-Truss-Ti Electron Beam Technology – which has been applied for the first time in spinal implant by LfC.

      Those implants constitute a new significant step in spine surgery due to their special function enhancing new trend in surgical treatment of the spine:

      The others about us:


        • Decompression & unloading of the neural Structures;
        • Acceleration of osteointegration:
          • acceleration of bone ingrowth & overgrowth of implant;
          • quick patient recovery;
        • For different surgical approaches;
        • Restoration of natural spine geometry;
        • Reduction of invasiveness – for MISS procedures;

        • Uniquely shaped carving guides for:
          • controlled insertion & precise placement;
          • supreme primary stability;
          • enlargement of load bearing surfaces;
          • prevention against migration & expulsion;
        • Anatomical „bullet” shape:
          • smooth insertion;
        • Specially designed 3D-Truss Ti structure:
          • minimal volume of titanium;
          • more than 65% space for bone ingrowth;
          • light & strong construction;
          • high load bearing capacity;
          • surfaces of 3D-Truss elements susceptible to osteointegration;
          • superior bony fusion;

    At the end of the 20th century, technologies stemming from aero-space engineering opened a world of new possibilities in 3D spatial architecture. LfC managed to transmit this space technology to the field of spinal implants. Electron beam melting (EBT-Electron Beam Technology) of Ti-alloy powder with temperatures over 2000 deg. C in a vacuum chamber -that is the essence of technology used to create a new generation of 3D-implants. Apart from the structure itself, which favors bone ingrowth within the spatial cells, the implant’s design enables an accelerated osteointegration mechanism reducing fusion time by 40-50 percent and more. This new phenomenon was studied and called „Ivy-like mechanism, L.C.” as a metaphor for the natural growth process of ivy, which climbs along the specially made rough surface of truss design.
