Figure 3: Halo Traction Use Case
Figure 4: Halo Traction Parts Labeled
As outlined in Appendix Halo Traction System Secondary Research, the halo traction system is used for spinal stabilization in patients with deformities or injuries. The system, consisting of a halo ring, metal pins, vest, and external weights, gradually adjusts spine curvature through tension. It is effective but has limitations like complexity, lack of adjustability, infection risk, and psychological impact. For detailed information, see the full document in the appendix.
Purpose
Gradually stretch spine
Stabilize and relieve stress on the spine
Types of Patients Served
Severe spinal deformities
Scoliosis, kyphosis, injuries
Components of Halo Traction
Halo Ring
Traction Device
Wheelchairs & walkers
Limitations of Current Solutions
Complex setup processes
Customization challenges
Discomfort / limited mobility
Unable to replicate for future needs
The halo traction equipment is primarily used on children with scoliosis or similar spinal formation problems. While some patients have flexible spinal curves, which allows them to receive a spinal fusion to remedy the problem immediately, others are not as flexible, and they must undergo halo traction therapy before surgery. At any given time, approximately four to five patients are using these devices, but Shriners wishes to increase the number of patients they can offer this treatment.
