Anterior Cervical Corpectomy

The human spine is an intricate structure, serving as the backbone of our body’s stability and mobility. However, conditions such as degenerative disc disease, trauma, tumors, or infections can compromise its integrity, leading to pain, numbness, and even paralysis. In such cases, surgical intervention becomes necessary to alleviate symptoms and restore function. One such procedure is Anterior Cervical Corpectomy (ACC), a surgical technique aimed at addressing specific spinal conditions affecting the cervical vertebrae.

Understanding Anterior Cervical Corpectomy

Anterior Cervical Corpectomy involves the removal of the vertebral body and adjacent intervertebral discs from the front of the neck, usually performed in the cervical spine (neck region). 

The procedure aims to decompress the spinal cord and nerve roots, relieving pressure caused by various conditions. Unlike Anterior Cervical Discectomy and Fusion (ACDF), which removes only the damaged disc, ACC addresses more extensive pathology, such as multi-level disc herniations, severe spinal stenosis, or tumors involving the vertebral body.

Indications for Anterior Cervical Corpectomy

  1. Degenerative Disc Disease: When degenerative changes in the cervical spine lead to disc herniation, bone spurs, or spinal stenosis, causing compression of neural structures.

  2. Trauma: Severe cervical spine injuries, such as fractures or dislocations, may require corpectomy to stabilize the spine and decompress neural elements.

  3. Tumors: Both primary and metastatic tumors affecting the cervical spine may necessitate corpectomy to remove tumor tissue and relieve pressure on the spinal cord.

  4. Infections: Infections such as spinal tuberculosis or osteomyelitis can erode vertebral bodies, leading to instability and neurological compromise, requiring corpectomy for debridement and stabilization.

The Surgical Procedure

Anterior Cervical Corpectomy is typically performed under general anesthesia with the patient lying on their back. The surgeon makes a small horizontal incision in the front of the neck, usually along a skin crease, to access the cervical spine. After careful dissection of soft tissues, the affected vertebral body and adjacent discs are exposed.

Using specialized surgical instruments, the surgeon meticulously removes the damaged vertebral body and any pathological tissue, taking care to avoid damage to surrounding structures such as the spinal cord and major blood vessels. Once the corpectomy is completed, the resulting defect is reconstructed to restore spinal alignment and stability.

Recovery and Rehabilitation

Following Anterior Cervical Corpectomy, patients typically require a brief hospital stay for monitoring and pain management. Depending on the extent of surgery and individual factors, recovery times may vary, but most patients can expect a gradual improvement in symptoms over several weeks to months.

Physical therapy plays a crucial role in rehabilitation, helping patients regain strength, mobility, and function. Initially, activities may be limited to avoid strain on the neck, gradually progressing as healing occurs. Patients are usually advised to avoid heavy lifting and strenuous activities for a period following surgery to allow for proper healing of the cervical spine.

Potential Risks and Complications

As with any surgical procedure, Anterior Cervical Corpectomy carries inherent risks and potential complications, including:

  1. Infection: Despite stringent sterilization protocols, there is a risk of postoperative infection at the surgical site.

  2. Bleeding: Excessive bleeding during surgery or in the postoperative period may require intervention.

  3. Nerve Injury: Damage to nerves or spinal cord during surgery can result in neurological deficits, though this risk is minimized with careful surgical technique.

  4. Hardware Failure: In cases where spinal instrumentation (such as plates and screws) is used for stabilization, hardware failure or loosening may occur.

  5. Nonunion or Pseudarthrosis: Failure of the bones to fuse adequately (nonunion) or the development of a false joint (pseudarthrosis) may necessitate further intervention.
