BIG ST
Anterior Lumbar Interbody Fusion
ST (Structural Titanium)
Variable implantation
Stand alone optional
Large contact area with the vertebral body
The ventral approach for the lumbar fusion system has long been established in spinal surgery due to the easy approach to the disc space. The Anterior Lumbar Interbody Fusion (ALIF) has the advantage of an extensive ventral release and the option of placement of larger cages than from the posterior direction. BIG® ST implants can be placed by traditional methods and also by minimally invasive techniques either transperitoneal or retroperitoneal. Here, the integrated, diverging bone screws form an angularly stable connection and ensure fixation and increased (stand-alone) implant stability. In combination with the simple instrument set and a wide range of implants the BIG® ST system offers an efficient and reliable solution for Anterior Lumbar Interbody Fusion (ALIF). When used in combination with the atraumatic, minimally invasive implant placement technique, it offers a high degree of multidirectional stability with the least possible traumatisation.
BIG® ST is placed by an ALIF (Anterior Lumbar Interbody Fusion) approach in the L1 – S1 spinal region. The cages are picked up at 0°, 45° or 90° in order to adjust the insertion technique to the actual surgical conditions.
The large fenestration in the implant permits the cage to be packed with natural or synthetic bone graft substitute such as KAINOS® Inject.
