What should you know about polyaxial pedicle screw?

The screw is placed through a vertebra’s pedicle, a strong part of the vertebral arch. Its head can pivot in more than one direction, allowing the surgeon to position a rod without requiring every screw and rod connection to line up at exactly the same angle. Screws and rods can help hold spinal segments in a planned position while bone heals after an operation. The device itself does not diagnose the cause of back pain, and its suitability depends on anatomy, bone quality, the spinal level and the planned procedure.

Before surgery, ask which levels will be treated, whether the construct is intended for [Spinal Fusion](/treatments/spine-care/spinal-fusion/), and how imaging guides screw placement. Follow instructions about medicines, smoking, wound care, lifting and walking after the operation. Rehabilitation usually progresses gradually, with movement and strengthening introduced according to healing and the surgeon’s plan. A [Pedicle Screw](/materials/pedicle-screw/) is one part of a larger fixation system, so do not judge recovery by the implant alone.

Contact the surgical team promptly for increasing wound redness, drainage, fever, new weakness, worsening numbness, or pain that changes sharply. Seek emergency help for loss of bladder or bowel control, rapidly progressing leg weakness, or severe breathing difficulty. After recovery, new or escalating pain should be assessed rather than assumed to be normal hardware discomfort.

Why is this screw design suitable for my anatomy? Which vertebral levels need fixation? Will the operation include [Scoliosis Surgery](/treatments/spine-care/scoliosis-surgery/)? What restrictions and follow-up imaging should I expect?
