Posterior Cervical Decompression and Fusion (PCDF)

Surgery to Relieve Spinal Cord Compression and Stabilize the Cervical Spine

Quick Summary

Posterior cervical decompression and fusion (PCDF) is a surgical procedure used to relieve pressure on the spinal cord or nerves in the neck and stabilize the cervical spine.

  • Commonly performed for cervical spinal stenosis and cervical myelopathy

  • Performed through an incision in the back of the neck

  • Removes bone and tissue compressing the spinal cord

  • Stabilizes the spine using screws, rods, and bone graft

  • Allows the vertebrae to fuse together over time

What Is Posterior Cervical Decompression and Fusion?

Posterior cervical decompression and fusion is a procedure designed to treat conditions that compress the spinal cord or nerve roots in the cervical spine.

During the surgery, the surgeon performs two main steps:

1. Decompression

Bone and thickened tissues that are pressing on the spinal cord or nerves are removed. This creates more space for the neural structures.

2. Fusion

The affected vertebrae are stabilized using screws and rods placed in the spine. Bone graft is placed to allow the vertebrae to fuse together over time.

Fusion prevents abnormal movement between vertebrae and helps maintain spinal stability after decompression.

When Is PCDF Recommended?

Posterior cervical decompression and fusion may be recommended when significant spinal cord or nerve compression occurs along with spinal instability.

Common conditions treated include:

  • Cervical spinal stenosis

  • Cervical myelopathy

  • Multilevel cervical degenerative disease

  • Cervical spine instability

  • Certain cases of cervical deformity

Surgery may be recommended when symptoms affect walking, hand coordination, or overall neurologic function.

How Is PCDF Surgery Performed?

PCDF surgery is performed through an incision in the back of the neck.

During the procedure:

  • The surgeon gently moves muscles aside to expose the cervical spine

  • Bone and thickened ligament compressing the spinal cord are removed

  • Screws and rods are placed into the vertebrae

  • Bone graft is placed to allow the vertebrae to fuse

These steps allow the surgeon to relieve pressure on the spinal cord while stabilizing the spine.

The procedure typically takes several hours, depending on the number of levels treated.

Benefits of Posterior Cervical Decompression and Fusion

Potential benefits include:

  • Relief of spinal cord compression

  • Prevention of further neurologic decline

  • Improvement in balance and coordination

  • Stabilization of the cervical spine

  • Reduction of nerve-related symptoms

For patients with cervical myelopathy, surgery often aims to prevent progression of neurologic symptoms and improve function.

Recovery After PCDF Surgery

Recovery after posterior cervical fusion varies depending on the number of levels treated and the patient’s overall health.

Typical recovery includes:

  • Walking soon after surgery

  • Hospital stay of one to several days

  • Gradual return to daily activities

  • Avoiding heavy lifting early in recovery

  • Physical therapy to improve strength and mobility

Fusion typically occurs over several months as the vertebrae heal together.

Risks and Considerations

PCDF is a commonly performed procedure, but all spine surgeries carry potential risks.

Possible risks include:

  • Infection

  • Bleeding

  • Nerve irritation

  • Failure of the bones to fuse

  • Persistent symptoms

Your surgeon will review the potential risks and benefits based on your specific condition.

When Should PCDF Be Considered?

This procedure may be appropriate when:

  • Spinal cord compression causes neurologic symptoms

  • Non-surgical treatments have not provided sufficient relief

  • Imaging confirms significant cervical spinal stenosis

  • Stabilization of the spine is necessary

Surgery is often recommended to relieve spinal cord compression and prevent worsening neurologic function.

Most Commonly Asked Questions

  • Posterior cervical fusion means stabilizing the spine from the back of the neck using screws, rods, and bone graft so that the vertebrae fuse together.

  • Fusion helps stabilize the spine after decompression and prevents abnormal movement between vertebrae.

  • The surgery typically takes several hours, depending on the number of levels treated.

  • Fusion eliminates motion at the treated levels, but many patients maintain good overall neck mobility.

    Shorter fusions maintain more neck mobility.

    Long fusions are only performed when necessary, and do limit neck motion significantly.

  • Bone fusion usually occurs over several months as the vertebrae heal together.

When should I see a spine specialist?

You should seek evaluation if you have:

  • Neck or arm pain persists despite treatment

  • You develop weakness, numbness, or coordination problems

  • Symptoms that interfere with daily activities

Early evaluation can help guide appropriate treatment.
