The WOMBAT is not only available in PEEK but also ST. WOMBAT® ST is manufactured from proven titanium alloy (Ti-6Al-4V).

WOMBAT® ST – Structural Titanium – is a TLIF cage with an open-pore titanium grid structure that, with its defined pore design, imitates the architecture of natural bone. The interconnection between the pores ensures optimal oxygen and nutrient supply, creating the optimal foundation for osseointegration. The implant also offers more space for fusion, with 70% of WOMBAT® ST consisting of pores. The roughness of the implant – in addition to its toothed endplate design that has been tried and tested by SIGNUS – optimises the primary stability and counteracts migration of the implant. In addition, the lateral surfaces are embedded in a smooth frame to minimise the required preparation and to protect the nerve structures during the implantation procedure.
