Halo gravity traction is a procedure that gradually stretches the spine in order to correct severe spinal conditions. For some children, it may be a better choice than surgery.
Halo gravity traction involves attaching a metal “halo” to a person’s head. A healthcare professional then attaches this to a weighted pulley system that gradually adjusts the spine.

Although the procedure may seem quite painful, some people experience immediate benefits, like breathing more easily and having less pain.
Read on to learn more about how halo gravity traction works.
Healthcare professionals may use halo gravity traction to treat
Halo bracing comes with risks, but specialists may consider it the safest option in some cases. For example, it can be a good choice for children, as their bones are still developing. In children and adolescents with severe spinal curvature, halo traction lowers the risk of nerve and tissue damage compared with surgical intervention.
It’s not always a replacement for surgery, however, and a doctor may recommend a less invasive surgical method afterward, such as spinal fusion.
First, your child will receive a general anesthetic, which means they’ll be asleep during the procedure. A healthcare professional will then attach a metal ring, or halo, to the skull using several pins.
They’ll then connect this halo to a weighted pulley system that gently pulls the head and spine upward. The process generally takes about 1 to 2 hours.
Over the span of about 3 to 12 weeks, the healthcare professional will add small increments of weight. This steady increase in force slowly stretches and realigns the spine.
Throughout the treatment, your child may use a wheelchair or walker, allowing for some mobility. And regular monitoring, including X-rays and neurological checks, ensures that the spine is responding appropriately to the traction.
Your child will typically stay in the hospital for the duration of their treatment. Throughout their stay, a healthcare professional will add a small amount of weight incrementally to the device, until the total weight is about 50% of the child’s weight.
Healthcare professionals will monitor your child closely to ensure that the process goes smoothly and to assess for any nerve issues. This process may include:
- vision and hearing tests
- eye movement tests
- X-rays
The healthcare team will likely encourage your child to move around with help from a wheelchair or walker. Also, it’s safe to do schoolwork or work throughout the treatment.
If your child needs to use the bathroom, they’ll temporarily detach from the halo device. And while they’re sleeping, a healthcare professional may significantly reduce the amount of traction or remove the device altogether. Ultimately, this depends on the doctor’s advice and what works best for each person.
Because your child will be under general anesthesia while a specialist is placing the pins, they shouldn’t feel any pain during the procedure. However, some people may experience a headache, soreness, or swelling around the pin sites in the hours or days that follow.
Other potential side effects may include:
- spinal pain or discomfort
- pin site infections
- pin loosening
According to a 2019 review of children undergoing halo gravity traction, these side effects are generally mild and easily manageable with help from muscle relaxants, antibiotics, and pin retightening.
Most halo gravity traction complications are mild, especially compared with the risks of surgery.
Beyond issues like discomfort or infection,
- nerve issues in the head or face
- infections or fractures around the eye
- double vision or other vision problems
- spinal nerve pain
- irregular heartbeat
- issues swallowing
- skull punctures
- breathing issues or pneumonia, though this is more common in older adults
A small
- 95% experienced complications
- 90% experienced cervical (neck) pain
- 36% experienced back pain
- 26% experienced minor neurological issues
- 5% experienced dizziness or pin displacement
The researchers note that complications, including infections and neurological issues, were minor and didn’t cause any long-term consequences. However, they say that further research in larger samples is needed before drawing any conclusions.
It’s important to note that because halo gravity traction is highly specialized, only a small number of hospitals and surgeons in the United States can perform this treatment.
If your child’s having halo gravity traction, there are a few things you can do to help them feel as relaxed as possible during the process. These steps include:
- Making them feel at home: During their hospital stay, plan to stay with them and bring their favorite toys, some games, or any decorations that may help them feel cozy and comfortable.
- Encouraging them to play (safely): Children don’t need to sit still and watch TV while wearing the device. They usually adjust to using a walker or wheelchair quickly and often benefit from some light exercise and fun.
- Helping them sleep peacefully: Your child will sleep in a specialized bed while in traction, but it may take some adjustment. Consider using a neck pillow or rolled-up towel to support their head while they get some shuteye.
Other tips to remember include:
- ensuring that your child avoids high impact activities for several months
- using only baby shampoo on their wounds
- monitoring for pain, numbness, or fever
Of course, always follow the doctor’s orders carefully to ensure a smooth healing process.
Although the procedure may come with complications, they’re somewhat minor compared with more invasive surgical procedures.
According to the authors of one
The authors of the same paper estimate that the success rate is about 85%. In one study the authors cite, about 121 people from a sample of 239 had minor complications.

Halo gravity traction is a reasonably effective way to correct severe spinal irregularities, especially for children and adolescents whose bones are still developing.
Due to the invasive nature of the device in the skull, it requires very delicate care and attention throughout the treatment process.
Serious complications are rare, and most people report benefits like reduced spinal pain and improved breathing.
