Thoracic vertebral body fracture after total hip replacement in diffuse idiopathic skeletal hyperostosis.

Abstract

This article describes the critical clinical sequelae of a patient with diffuse idiopathic skeletal hyperostosis who sustained an acute iatrogenic thoracic vertebral body fracture with subsequent spinal cord injury after a total hip replacement, with a final lethal course.A 57-year-old woman was referred to the authors' institution after undergoing a total hip replacement in the supine position for secondary osteoarthritis. Postoperatively, the patient had symptoms of an incomplete paraplegia. Computed tomography scan and magnetic resonance imaging revealed diffuse idiopathic skeletal hyperostosis and an acute unstable fracture of T11 with spinal contusion. A posterior spinal fusion of T10-L1 with laminectomy of T11 was performed immediately on admission. Postoperatively, no improvement of the neurological deficit was observed. After developing multiorgan failure while in intensive care, the patient died 2 months after the total hip replacement.The morphological and functional symptoms of diffuse idiopathic skeletal hyperostosis with the typical ossification of the longitudinal ligaments and the associated loss of bending forces of the spine were detected postoperatively. This severe case demonstrates that the surgeon must be alert to possible complications due to intraoperative maneuvers in patients with stiffened spinal disorders undergoing total hip replacement.
