Is cervical fusion done with PEEK spinal cage?

During cervical fusion, a damaged disc may be removed and the space supported with an implant so bone can grow across the treated level. A PEEK cage is made from a radiolucent polymer, which can make the surrounding bone easier to assess on follow-up imaging. Some cages contain markers or are combined with bone graft material, and a plate or other fixation may also be used. PEEK is one option among several. The choice depends on the disc level, neck alignment, bone quality, stability and the surgeon’s preferred construct.

Ask your spine specialist to show which level is affected and explain the purpose of the cage, graft and any plate or screws. Discuss expected neck movement, lifting limits, driving, work and the rehabilitation plan. Share any history of previous neck surgery, bone-healing problems, smoking or medicines that affect bone, because these can influence planning. Before surgery, follow the team’s instructions and report new symptoms rather than changing activity independently.

Seek prompt medical advice for worsening arm weakness, loss of hand coordination, increasing numbness, difficulty walking or changes in bladder or bowel control. After surgery, urgent assessment is needed for breathing or swallowing difficulty that is worsening, sudden weakness, severe neck swelling, fever with wound drainage, or new loss of balance. These symptoms need direct review and should not be explained only by the implant.

Ask why a PEEK cage suits your case, whether it will contain graft material, whether additional fixation is planned, and how fusion will be monitored. Ask what symptoms are expected during recovery, which changes are urgent, and when rehabilitation can begin.
