Z. Israel et al., HYPEREXTENSION FRACTURE-DISLOCATION OF THE THORACIC SPINE WITH PARAPLEGIA IN A PATIENT WITH DIFFUSE IDIOPATHIC SKELETAL HYPEROSTOSIS, Journal of spinal disorders, 7(5), 1994, pp. 455-457
The case is described of a hyperextension thoracic spine fracture in a
patient with diffuse idiopathic skeletal hyperostosis (DISH). A 70-ye
ar-old woman awoke paraplegic after retroperitoneal surgery after havi
ng been positioned in the hyperextended axially rotated position. Imag
ing demonstrated a T9-10 fracture-dislocation with severe pressure on
the spinal cord, as well as findings typical of DISH. This case emphas
izes the danger inherent in manipulating the ankylosed hyperostotic sp
ine. It is proposed that patients undergoing surgery in this position
should be evaluated for DISH as an additional risk factor.
