VLIFT Vertebral Body Replacement System
The VLIFT system utilizes a distractible in-situ (DIS) implant which enables the surgeon to adjust the height of the cage to suit the anatomy of the patient. The pre-assembled VLIFT cage adjusts easily with a low profile inside thread design. The cage also includes a pre-assembled locking screw which can be engaged after distraction to lock the mechanism in place. Cage extensions snap into place on each end to build a longer implant construct. For example, an 18mm cage in width that is 60mm in length can be extended to 75mm in length with an extension at one end and up to 90mm in length when using two extensions. Modular end-caps snap into each end for quick assembly. The exterior side of the end-caps feature evenly spaced metal spikes, providing fixation to the bony endplates of adjacent vertebral bodies. The use of bone graft with VLIFT is optional.
VLIFT is a vertebral body replacement system intended to replace a vertebral body or an entire vertebra in the thoracolumbar spine (T1-L5). For both corpectomy and vertebrectomy precoedures, the VLIFT system is intended to be used with supplemental internal fixation systems (Xia, Spiral Radius 90D, or Trio+).
Features & Benefits
Key advantages include:
- Single, pre-assembly cage
- Large windows for in-situ insertion of bone graft into cage Cage diameters: 18mm and 22mm
- Cage lengths 16mm-70mm, 25mm-70mm
- Cage and end caps made of titanium alloy
- Cage extensions: 18mm, 22mm diameter x 15mm long
- Modular end caps with large surface area for load bearing to prevent subsidence and aid stabilization of affected motions segement(s)
- End caps: flat angle or with inclines (0, 3 or 8 degree) match lordsis of spinal segment
- Open end caps to maximize bone-to-bone graft contact
- Lordotic options to build a 0, 3, 6, 8, 11, or 16 degree construct
- Single surgical instrument for simple insertion and distraction
- Titanium alloy for mechanical integrity during impaction/distraction, X-ray visibility, MRI compatibility, biocompatibility
- Implant and instrument ideal for anterior/antero-lateral approaches
