What should you know about s1 pedicle screw?

The sacrum connects the spine to the pelvis. An S1 screw is positioned in strong bone at the back of the sacrum and connected to rods or other implants to hold spinal segments in planned alignment while fusion develops. The operation may address instability, deformity, a slip between vertebrae, or the need to support a decompressed area. The implant itself is not a treatment for every source of back or leg pain. Imaging and examination guide the size, path, and number of screws. Learn more about the [Pedicle Screw](/materials/pedicle-screw/) as an implant.

Discuss bone health, nicotine use, medicines, allergies, and prior operations before surgery. Afterward, follow instructions about walking, bending, lifting, wound care, and physiotherapy. Early discomfort around the incision is common, while nerve symptoms may take longer to settle. Keep follow-up appointments so the team can review healing and alignment. A screw may be used within [Spinal Fusion](/treatments/spine-care/spinal-fusion/) or, in selected deformity cases, [Scoliosis Surgery](/treatments/spine-care/scoliosis-surgery/).

Seek prompt advice for fever, wound drainage, increasing redness, new weakness, worsening numbness, or pain that suddenly changes. Emergency assessment is needed for new bladder or bowel control problems, numbness in the saddle area, or severe weakness in both legs. A fall or impact during recovery should be reported, especially if it causes new pain or difficulty walking. Do not adjust a brace or activity restriction without guidance.

Ask: Why is fixation needed at S1? Will the screw connect to the pelvis? What does imaging show about bone quality? Which movements are restricted? How will fusion and hardware be checked?
