Cervical Halo

What is a Cervical Halo?

A cervical halo (also called a halo vest or halo brace) is a medical device used to completely immobilize the head and neck so that the cervical spine (neck) can heal after a serious injury or surgery.

The device consists of three main parts:

Halo ring: A lightweight metal ring that surrounds the head. It is attached to the skull using 4–8 small pins.

Support rods: Metal rods connect the halo ring to the vest.

Vest: A rigid vest worn on the chest and shoulders that keeps the entire device stable.

Together, these parts prevent almost all movement of the neck.

When is a Cervical Halo used?

Doctors may recommend a halo for:

• Cervical spine fractures (broken bones in the neck)
• Unstable cervical spine injuries
• Certain ligament injuries of the neck
• After surgery to stabilize the cervical spine
• Some congenital or developmental neck conditions in children

The goal is to allow the bones and ligaments to heal in proper alignment while avoiding additional spinal cord injury.

How is a Cervical Halo Placed?

A cervical halo is typically placed under local anesthesia with sedation or, in some cases, general anesthesia. After cleaning the scalp, a lightweight metal halo ring is positioned around the head and secured to the skull with specialized pins. A rigid vest is then fitted around the chest and shoulders, and metal rods connect the ring to the vest to stabilize the head and neck. Imaging is used to confirm proper alignment. Patients receive instructions for pin-site care, skin care, and activity restrictions, with regular follow-up visits to monitor healing and adjust the device if needed.

How long is a Cervical Halo worn?

Most patients wear a halo for 6 to 12 weeks, although the exact duration depends on:

• The type of injury
• Healing progress
• Follow-up X-rays or CT scans

Advantages of a Cervical Halo

• Provides the highest level of external neck immobilization available.
• May eliminate the need for surgery in some fractures.
• Helps maintain proper alignment during healing.

Possible complications of a Cervical Halo

Although effective, halo braces can have complications, including:

• Pin-site pain or infection
• Pin loosening
• Difficulty sleeping
• Trouble with balance due to the added weight
• Skin irritation or pressure sores beneath the vest
• Difficulty with daily activities such as dressing and bathing

Patients require regular follow-up visits so the healthcare team can check pin tightness, skin condition, and healing.
