MOBIS® II ST  – Variable and reliable implantation from SIGNUS

MOBIS® II ST is placed by a TLIF (Transforaminal Lumbar Interbody Fusion) approach in the L1–S1 spinal region.

Its arc-like profile with large hollow openings guarantees a large contact surface with the bone. With its shape MOBIS® II ST is an ideal fit to the anterior curve of the vertebral body.

The inserted cage, combined with additional posterior instrumentation, leads to immediate biomechanical stabilisation. This establishes the ideal conditions for vertebral body fusion.

The large selection of implants provides for a high degree of intraoperative flexibility and ensures restoration of the intervertebral space. In addition to plane-parallel implants, the MOBIS® II ST cage is also available with a 5° lordotic angle.
