Interbody cages are placed between vertebrae to restore disc height and promote bone fusion. Pedicle screws and rods are used to stabilise the spine during healing. The spinal fusion market research shows that interbody cages hold the largest share, but pedicle screws and rods are the fastest‑growing. Why? Because complex deformities (scoliosis, kyphosis) need stronger fixation.
What's the difference? Cages are made of PEEK (plastic), titanium, or bone. PEEK is radiolucent (you can see bone growth through it), but titanium has better osseointegration. The spinal fusion market trends highlight that the fastest‑growing product is spinal fusion plates, used in anterior cervical fusion.
New materials: 3D‑printed porous titanium that encourages bone ingrowth, and bioresorbable cages that dissolve over time.
The bottom line: your surgeon will choose the implant based on your diagnosis, anatomy, and surgical approach. Don't get hung up on the brand — focus on the surgeon's experience.
