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 and 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

The ADD (anterior distraction device) implant is a distractable vertebral body replacement for the anterior cervical and thoracic spine. The is used for reconstruction of bone mass defects and the spinal profile as well as for support and stabilization of the anterior spinal column. Additional ventral or dorsal stabilization is necessary.
ADDplus(anterior distraction device plus) is likewise a vertebral body replacement used in the reconstruction, support and stabilization of the anterior cervical spine and the cervico-thoracic transition. ADDplus resulted from the rigorous ongoing optimization of our ADD and osmium systems. This direct combination of vertebral body replacement and ventral plating unites two systems. Fixation on the vertebral bodies is achieved using osmium (hyperlink) screws. Both monocortical and bicortical screw anchorage can be used.
Both implants are used to correct instability of various origins, resulting from tumors or fractures, for instance. They are continuously distractable in situ, so that precise bridging of the defect is ensured.
