[Dorsal interapophyseal arthropathy and spinal cord compression in syringomyelia]

A dorsal spinal cord compression by exuberant arthropathy and osteophytes of the articular processes occurred in a 61 years old patient with syringomyelia. The clinical symptoms were related to postero lateral cord involvement and rapidly appeared after syringo-peritoneal shunting. C.T. scan precisely displayed the pathological process and the cord compression. Surgery enabled a definite amelioration of secondary sensory deficits. It was to our knowledge the first description of such an involvement of articular processes in syringomyelia.
