[Vertebral osteonecrosis. Apropos of 4 cases with slow spinal cord compression in 1 case].

The authors report on four cases of aseptic osteonecrosis of the vertebral body in adults (VON). Among these, one patient, in whom histological data were available, presented with a slow spinal cord compression syndrome (SSCCS). This complication is uncommon since only one other similar case has been reported so far (4).
