Easy implanation – maximum support
Because of the protection it affords the spinal canal and the stabilising posterior structures, transforaminal fusion has become a widely used technique. WOMBAT® is a TLIF implant (Transforaminal Lumbar Interbody Fusion) that is positioned diagonally in the intervertebral space, unlike classic banana-shaped cages. This allows bilateral support to be achieved in spite of the unilateral access – and that with a surgical procedure involving just one step!
WOMBAT® is placed by a TLIF (transforaminal lumbar interbody fusion) access in the L1 – S1 spinal region. Besides the simple implantation procedure, the area of contact with the implant and the filling volume can in addition be maximised by utilisation of the entire diagonal diameter of the vertebral body. With its biconvex design WOMBAT® is an ideal fit to the curve of the vertebral body.
The large fenestration in the implant permits the cage to be packed with natural or synthetic bone graft substitute such as KAINOS® Inject.
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 WOMBAT® cage is also available with a 6° lordotic angle.
WOMBAT® ist either available as solid titanium (Ti-6Al-4V) or as high-‑performance PEEK‑ OPTIMA®.
