[A case of psoriatic arthropathy complicated with spinal fracture and epidural hematoma].

ABSTRACT

A 78-year-old man with psoriatic arthropathy complicated with traumatic spinal fracture and epidural hematoma is reported. He had fallen down the stairs. On admission one hour after injury, he developed an incomplete C6 quadriparesis. CT revealed a C6-7 fracture and dislocation on sagittal reconstruction. MR imaging disclosed the compression of the spinal cord between the posterior margin of the vertebral body and an epidural hematoma. The patient had had the skin lesion, psoriasis vulgaris, for about 20 years and been previously treated for uveitis. Serological tests for rheumatoid factor and HLA B-27 were negative. Emergent laminectomy and evacuation of the epidural hematoma were carried out because of progressive neurological deterioration. Osteoporotic laminar bone and ossified yellow ligament were observed to have been fractured. Conservative therapy was selected for spinal instability. Although a respiratory complication occurred postoperatively, he was transferred to the rehabilitation facility in an improved neurological condition.
