BACKGROUND: Patients suffering from ankylosing spondylitis are prone to injuries of the cervical spine even with minor trauma. Although the fractures are markedly unstable, nonsurgical treatment using a halo-thoracic plaster or jacket is a common approach. METHODS: We present three patients with cervicothoracic fractures of the ankylosed spine to describe problems and complications inherent in this type of treatment. In two, pin track infections and pin protrusion through the skull occurred, leading in one case to an intracerebral hemorrhage. In the third patient, the halo had to be removed after 8 months, just early enough to prevent the pins from cutting through. RESULTS: One patient required craniotomy. The second one could be resolved by local revision. In the third case, the fracture eventually united after using a stiff collar for 2 years. CONCLUSION: Halo treatment for cervical spine fracture in patients with ankylosing spondylitis is a challenging task for orthopedic surgeons and neurosurgeons.
