What is a PEEK spinal cage used for?

PEEK is a strong, lightweight polymer used in some spinal implants. During fusion surgery, the damaged disc can be removed and the cage placed between neighbouring vertebrae. Its shape helps preserve height and alignment, while bone graft material inside or around it can encourage the vertebrae to join. The cage may be used in the neck or lower back, depending on the operation. It is one part of a larger plan and may be combined with plates, screws, or rods for added stability.

Before surgery, ask which spinal level is involved, whether additional fixation is planned, and how bone healing will be assessed. Follow instructions about lifting, driving, wound care, and physiotherapy. Keep follow-up appointments because symptoms and imaging together help the team judge recovery. Do not change pain medicine or activity restrictions without guidance.

Get urgent help for new arm or leg weakness, loss of coordination, severe difficulty walking, or new bladder or bowel control problems. Call the surgical team promptly if you develop fever, increasing wound redness or drainage, swallowing or breathing difficulty after neck surgery, or rapidly worsening pain.

Why is a cage suitable for my spinal level? Will it be used with screws or a plate? What signs show that the fusion is progressing, and which activities should wait during healing?
