Doctors at the M. D. Anderson Cancer Clinic in Houston, Texas have reported on the results of patients receiving radiation in similar circumstances. There were 35 patients treated with external beam radiation and/or surgery. The main symptoms were pain and neck instability.
The results showed that everyone got good pain relief. Some of the patients who had surgery didn't have as good a result as those who had radiation alone. It appears from that study that radiation may be all that is needed. Patients may be able to avoid surgery and still get relief from pain and increased stability of the neck.
Everyone wore a neck collar after treatment with radiation and/or surgery for at least three months. It's not clear how long an external cervical orthosis of this type is really needed. Some patients wore it for many months. Others stopped wearing it when they were pain free and the X-rays showed the fractures were healed.
