Ray Threaded Fusion Cage PLIF
This interbody device is a hollow threaded cylinder with fenestrations for bone-to-bone contact and promotes spinal fusion by producing an optimal fusion environment. The Ray TFC is indicated for use with autogenous bone graft in patients with degenerative disc disease at levels S1 through L2 (one or two levels) and in cases of Grade 1 Spondylolisthesis. Degenerative Disc Disease (DDD) is defined as back pain of discogenic origin with degeneration of the disc confirmed by history and radiographic studies. These patients should be skeletally mature and have six months of nonoperative therapy. The Ray TFC is to be implanted via open ALIF or open PLIF procedures. The unique biomechanics of the system enable load sharing between the device and the spine. Axial load is distributed to the bone graft while maintaining disc height. Two devices are implanted per level. They are placed laterally to the midline and packed with autogenous bone graft while a high-performance polyethylene end cap is set in place.
Features & Benefits
Key advantages include:
- Composed of high-strength titanium alloy
- Comes in five diameters and two lengths
- Biomechanics distribute axial load to the bone graft while focusing on end plate preservation
- 70 percent fenestration provides exposure for bone-to-bone contact
- Each instrument introduced is sequentially larger, providing fixation of the implant
