- Traumatic injuries to the spine.
- Degenerative disc disease.
- Congenital spinal deformities.
- Previous spinal surgeries that have failed.
Diagnostic Tests Before Procedure
Several diagnostic tests are typically performed to assess the need for this procedure.
- X-rays to evaluate spinal alignment and stability.
- MRI scans to assess soft tissue and nerve involvement.
- CT scans for detailed imaging of the bony structures.
- Electromyography (EMG) to evaluate nerve function.
Procedure Description
The procedure involves several key steps to ensure successful spinal fusion.
- Patient is placed under general anesthesia.
- An incision is made along the back to access the spine.
- Damaged or unstable vertebrae are identified.
- Bone graft material is placed to promote fusion.
- Metal rods and screws may be used to stabilize the spine.
- The incision is closed with sutures or staples.

- Gradual return to normal activities over several weeks.
- Physical therapy may be recommended to aid recovery.
- Pain management with prescribed medications.
Possible Complications
As with any surgical procedure, there are potential risks involved.
- Infection at the surgical site.
