The Halo ring can also be utilized as a fixation device to the skull to apply traction to the cervical spine post-trauma in an effort to realign the cervical spine and reduce compression on the nerve roots or spinal cord. It is sometimes used pre-surgically to maximize alignment of the spine or reduce a deformity to optimize surgical outcomes.

The Halo vest may be applied post-traction or post-surgery to maintain achieved spinal alignment.
