On a HALO, should the headblocks be positioned above or below the ring?

The proper positioning of headblocks in a HALO (Halo-Gravity Traction) device is crucial for providing the necessary stabilization and alignment of the cervical spine. When the headblocks are placed above the ring, it allows for effective distraction and alignment of the vertebrae, which is essential for treating conditions such as cervical fractures or other spinal instabilities.

By positioning the headblocks above the ring, traction can be effectively applied to the head and neck region. This positioning assists in immobilizing the head, thus preventing further injury and promoting healing. Additionally, it helps maintain proper anatomical alignment, which is vital for the patient's recovery process.

Proper placement of headblocks is integral to the effectiveness of the HALO device, reinforcing the necessity of their correct positioning for optimal patient outcomes.
