Cervical spine fusion is one of the most recommended surgeries for treating chronic and severe neck pain, as it has been proven effective in patients experiencing neurological issues such as numbness in the arms and hands.
This procedure has a high success rate of 85-95% in significantly reducing pain and restoring normal daily activities. Thanks to these advantages, cervical spine fusion has become the preferred choice for patients suffering from neck pain.
What is cervical spine fusion surgery?
Most neck pain stems from degenerative changes in the intervertebral disc. While not all patients with neck pain require surgery, when nonsurgical treatments fail to provide relief, doctors may recommend cervical spine fusion surgery as an effective procedure for chronic neck pain.
Cervical spine fusion surgery alleviates pressure on affected spinal nerves and stabilizes the cervical spine by fusing vertebral bones at one or more levels. There are multiple approaches to this procedure, with one of the most common being performed through the front of the neck, where the intervertebral disc is removed, earning the name Anterior Cervical Discectomy and Fusion (ACDF). This method offers advantages over posterior spinal fusion as it allows spinal canal decompression without impacting the spinal cord. Beyond these techniques, cervical spine fusion can also be performed laparoscopically, known as endoscopic minimally invasive spinal fusion surgery.
How do I prepare for cervical spine fusion surgery?
Cervical spine fusion surgery requires preparation, like any other surgical procedure. Doctors typically request tests and examinations to assess the patient’s overall health, such as X-rays and magnetic resonance imaging (MRI). In some cases, the surgeon may recommend a cardiologist consultation before proceeding with the operation.
Before undergoing cervical spine fusion, it is essential to inform your doctor about factors that may impact recovery, including cigarette smoking, which can hinder healing, alcohol consumption, existing illnesses such as colds or flu, and both prescription and over-the-counter medications. Your doctor may provide specific instructions if you take medications that affect blood clotting, such as anticoagulants (blood thinners) like warfarin, or nonsteroidal anti-inflammatory drugs (NSAIDs), including aspirin and ibuprofen. Since cervical spine fusion is performed under general anesthesia, patients must fast for eight hours before the operation. However, a small amount of water may be allowed to take medications prescribed by the doctor.
How is anterior cervical discectomy and fusion (ACDF) surgery performed?
Before undergoing cervical Spine Fusion, doctors may recommend laboratory tests and X-rays based on the patient’s condition. These assessments provide essential insights into the patient’s overall health and determine how well their body can tolerate the surgical procedure.
The surgery is performed under general anesthesia, meaning the patient will be unconscious throughout the whole operation. Initially, the doctor makes a small incision in the neck to access the targeted area of the Cervical Spine, using X-rays to ensure precision. The surgeon then removes damaged tissue, adjacent bone spurs, and the affected intervertebral disc. Then, a bone graft is placed in the disc’s position to prevent abnormal neck movements and fuse with the surrounding vertebrae. This graft may be sourced from the patient’s hip bone or a bone bank after compatibility testing.
The surgeon then secures the vertebrae with metal screws and plates, which helps minimize the risk of cervical spine fusion failure. Finally, the surgical incisions are closed, and the patient is transferred to the recovery room, where medical staff monitor their condition until they regain consciousness.
How is Posterior cervical fusion (PCF) surgery performed?
Cervical spine fusion performed through a posterior approach follows a similar process to anterior resection and is conducted under general anesthesia. The surgeon makes a longitudinal incision at the back of the neck, ranging from 7.5 to 15 cm, depending on the number of cervical vertebrae involved. X-rays guide the procedure, ensuring that the correct vertebrae are targeted for fusion.
After confirming the targeted area, the surgeon excises part of the lamina and removes bone spurs, if necessary. The cervical vertebrae are then stabilized using two small metal screws, connected by a titanium rod. Next, the bony surfaces and facet joints are scraped, and a bone graft is placed between the two vertebrae, which gradually fuses over the following weeks. Finally, the surgeon washes the wound area with an antibiotic solution, ensuring cleanliness before closing the incision.
When do I need cervical spine fusion surgery?
Cervical spine fusion is a highly effective procedure for relieving pain, restoring neck stability, and improving neurological function by alleviating pressure on the spinal cord and nerves. Below are some of the symptoms that may indicate the need for this surgery:
- Numbness and tingling in the hands and fingers
- Weakness in the arms and hands
- Difficulty with balance and walking
- Severe neck pain
What conditions and diseases require cervical spine fusion surgery?
- Degenerative diseases: spinal stenosis, cervical spondylolisthesis, osteoarthritis, and degenerative disc disease.
- Structural deformities: hunchback, vertebral imbalance, or spinal instability.
- Injuries: particularly to protect the spinal cord from further damage.
- False fracture: cases where spinal stability is impaired.
What are the complications of cervical spine fusion surgery?
No surgery is entirely without possible complications or side effects, including cervical spine fusion. Since the surgeon operates near the spinal cord, neck surgeries require precision and come with potential complications. Below are some possible complications associated with cervical spine fusion:
- Incomplete fusion: Lack of bone growth between neighboring vertebrae
- Nerve damage: Symptoms such as arm weakness, voice changes, or difficulty lifting the eyelid
- Difficulty swallowing
- Bleeding
- Infection
- Spinal cord injury
- No improvement in symptoms
- The possibility of needing additional surgery in the future
What is the success rate of cervical spine fusion surgery?
Cervical spine fusion has a high success rate in treating neurological symptoms and neck pain. However, results differ depending on each individual case and several contributing factors. Below are key success rates associated with cervical spine fusion:
- Herniated disc: 90-95% success rate in relieving arm pain
- Spinal stenosis: Neurological symptoms improve by 85-90%
- Spinal instability: 80-90% effectiveness in restoring spinal stability
Several factors affect the overall success of the procedure. For example, patients under 60 experience a 92% success rate. Additionally, the number of fused vertebrae influences the outcome. So, fusion of one vertebra achieves a 95% success rate, while fusion of three vertebrae reduces the rate to 85%.
What is the recovery time after cervical spine fusion surgery?
The recovery time for cervical spine fusion is determined by symptom improvement and bone healing across the fused vertebrae. On average, this process takes two to three months, with permitted activities depending on the strength of the fusion. Patients concerned about their ability to achieve complete fusion may require a more cautious recovery approach. Research indicates that beginning a physical therapy program after cervical spine fusion is beneficial and supported by medical evidence, typically after a minimum recovery period of five weeks. Therapy focuses on:
- Restoring the functional range of motion
- Boosting muscular strength
- Reducing the inflammatory response
- Teaching proper postures and movements to protect the stabilized area
In conclusion, cervical spine fusion is one of the most effective treatments for neck pain and neurological issues affecting the arms and hands. However, it is essential for patients to fully understand both the risks and the benefits of the procedure. A comprehensive medical evaluation and a strict commitment to post-operative care are crucial to a successful recovery.
