Posterior Cervical Fusion

Posterior Cervical Laminectomy and Fusion

What is Posterior Cervical Fusion?

Posterior cervical fusion (PCF), a surgical procedure performed through the back of the neck, involves joining or fusing two or more damaged cervical vertebrae. The fusion of vertebrae is also known as arthrodesis. Sometimes, metallic plates may be used for fixing the vertebrae, this is also known as instrumentation. 

Indications of Posterior Cervical Fusion 

PCF may be employed for the management of cervical fractures, bone dislocations and deformities due to an abnormal curvature of the cervical vertebrae. 

Posterior Cervical Fusion Procedure

The procedure is conducted in an operating room under general anesthesia. You will be made to lie face down on the operation table. A small incision is made over the center of the back of the neck. The muscles and the soft tissues are then retracted to approach the spine. X-ray imaging is employed to identify the affected intervertebral disc. The surfaces of the lamina of each vertebra to be fused are trimmed. This results in bleeding, which aids in rapid healing of the fused bones. In addition, small strips of bone graft taken from the pelvis are placed over the spinal column, which aids in the fusion of the bones. 

Confirmatory X-rays may be taken to confirm the proper placement of the bone graft. Finally, the retracted muscles and soft tissues are placed in their normal positions and the wound is sutured.

Postoperative Care following Posterior Cervical Fusion

You maybe discharge from the hospital within a week to 2-3 days of the surgery. A neck brace may be provided depending on how strong your bones are and how extensive the surgery was. However, this restriction may not be required if the vertebrae are fixed with a metal plate during the PCF surgery. You are initiated on a liquid diet, which is gradually changed to solid food depending on your recovery. 

Physical therapy is recommended after 4-6 weeks of the surgery. Physical therapists help you perform routine activities without exerting any extra stress on the neck. Rest is advised as it helps in healing of the bone graft.

Risk and Complications of Posterior Cervical Fusion

Every major surgery is associated with potential complications. Some of the complications associated with posterior cervical fusion include:

  • Complications related to anesthesia 
  • Thrombophlebitis (blood clot due to an inflammatory process)
  • Non-union or pseudarthrosis
  • Infection
  • Damage to the spinal nerves
  • Problem related to bone graft
  • Persistent pain
