Correction of chin-on-chest deformity in ankylosing spondylitis through a fracture site. A case report.

Correction of flexion deformity is possible in patients with a fracture through the ankylosed spine. In a 68-year-old man the correction was sustained by skull tong traction, while the neurologic condition was monitored. Posterior fusion may improve stability as the bone of patients with ankylosing spondylitis tends to be osteoporotic.
