Minimally Invasive Pedicle Screw Fixation
Minimally invasive pedicle screw fixation is a technique used to stabilise the spine using screws and rods placed through small incisions. This approach avoids the extensive muscle dissection associated with traditional open surgery.
When is minimally invasive pedicle screw fixation needed?
Pedicle screw fixation may be recommended to stabilise the spine in conditions such as:
- Spinal fractures
- Degenerative instability
- Spondylolisthesis
- After tumour removal
- As part of spinal fusion procedures
Stabilisation helps reduce pain, correct deformity, and protect the spinal cord and nerves.
How is minimally invasive pedicle screw fixation done?
Using X-ray or navigation guidance, screws are inserted through tiny incisions into the pedicles of the vertebrae. These screws are then connected with rods to stabilise the affected spinal segment. Because the incisions are small and the muscles are not detached from the bone, recovery is faster with significantly less postoperative discomfort.
