Thoracolumbar fracture dislocation sustained during childbirth in a patient with ankylosing spondylitis.
Spine J. 2012; (11): e5-8
Ankylosing spondylitis (AS) is a major subtype of the spondyloarthropathies. Uncoupling of bone formation and resorption along with ectopic ossification of paraspinal soft-tissue structures alters the biomechanics of the spine and leads to an increased susceptibility to fracture.
