Can a spinal fusion break?
Implant Failure in Spine Surgery
An instrumented fusion can fail if there is not enough support to hold the spine while it is fusing. Therefore, spinal hardware (e.g. pedicle screws) may be used as an internal splint to hold the spine while it fuses after spine surgery.
Can spinal fusion get worse?
And gradually over time, just like they’re healing a broken bone, they become fused. There is a small percentage of people that simply do not complete this healing process for a variety of reasons, and this can cause them to feel worse many months, or even years, after their previous surgery.
What are the symptoms of a failed lumbar fusion?
- Formation of scar tissue.
- Recurring or persistent disc disease at adjacent levels.
- Continued pressure from spinal stenosis.
- Instability or abnormal movement.
- Pseudoarthrosis or failure of the fusion.
- Nerve damage within the nerve, arachnoiditis.
Can screws come loose after spinal fusion?
Pedicle screw loosening is a common complication after spine surgeries. Traditionally, it was assessed by radiological approaches, both X-ray and CT (computed tomography) scan, while reports using mechanical method to study screw loosening after spine surgery are rare.
What happens if a screw comes loose after spinal fusion?
Chappuis, the most common pedicle screws used by spine surgeons loosen or break over time. If pedicle screws loosen, it may result in new or worsening back pain, leading to failed back surgery syndrome (FBSS).
How long will my back hurt after spinal fusion?
As the back continues to heal, patients usually start to feel better and find they can take on more activities. The worst pain is generally over by 4 weeks after surgery. Pain is likely to continue to decrease gradually, but some patients continue to have pain 3 to 6 months after surgery.

Why does my back still hurt after spinal fusion?
The formation of scar tissue near the nerve root (also called epidural fibrosis) is a common occurrence after back surgery—so common, in fact, it is so common that it often occurs for patients with successful surgical outcomes as well as for patients with continued or recurrent leg pain and back pain.
How long does it take for bones to fuse after spinal fusion?
With spinal instrumentation and fusion working together, new bone will grow around the metal implants – similar to reinforced concrete. Figure 2. After 3 to 6 months new bone growth will fuse the two vertebrae into one solid piece of bone.
Why do my hips hurt after lumbar fusion?
There are three possible causes of SIJ pain: (1) an increased mechanical load transfer onto the SIJ after fusion; (2) bone graft harvesting in the iliac crest close to the joint; and (3) the misdiagnosis of an SIJ syndrome before fusion (i.e., the lumbar spine is thought, erroneously, to be fused) .
How long does it take for nerves to heal after spinal fusion?
Spinal fusion surgery recovery typically takes anywhere from three to six months, and this time frame includes the various types of physical therapy that each patient must undergo.
What percentage of spinal fusions are successful?
Depending on the condition the surgery is treating, spinal fusion has a 70 to 90% success rate.
