BAK/Proximity™ Posterior

The BAK/Proximity™ Interbody Fusion System consists of both implants and associated implantation instruments. The Proximity Implant is a hollow, porous, square-threaded device made of titanium alloy (Ti-6Al-4V). Seven sizes of implants are available. The Proximity System has completed rigorous FDA clinical studies and is available for anterior open (ALIF), laparoscopic (ALIF) and posterior (PLIF) procedures. The studies have shown high fusion rates, quick pain reduction, rapid functional improvement, and much lower reoperation rates compared to conventional fusion methods.

The reproducible procedural effectiveness of any spinal fusion implant system is evaluated by accuracy, precision and safety of implant placement. Zimmer Spine developed the Proximity System to comply with these critical procedural parameters, while creating instruments which are easy to use.

More Porosity
  • The BAK/Proximity™ Implant is extremely porous in the critical decorticated area, placing more bone graft in close proximity to the vertebrae.
  • Large holes permit bony through growth in difficult fusion situations.
  • Large holes permit verification of fusion radiographically.
