In medicine the Holdsworth fracture is an unstable fracture dislocation of the thoraco lumbar junction of the spine. The injury comprises a fracture through a vertebral body, rupture of the posterior spinal ligaments and fractures of the facet joints.^[1]

The injury was described by Frank Wild Holdsworth in 1963. He described the mechanism of this injury as a flexion-rotation injury, and said that the unstable fracture dislocation should be treated by fusion of the two affected vertebrae.^[2]
