Abstract
An interspinous device for impeding the movements of two successive vertebrae (8, 9) of the spinal column. In some embodiments, the device includes two pads (2a, 2b; 11a, 11b; 20a, 20b) whose internal faces (3a, 3b; 12a, 12b) are intended to be pressed against the lateral faces of the spinous processes (6, 7) of the vertebrae (8, 9), and ligaments (4, 5a, 5b, 5c, 5d; 17a, 17b, 18, 19; 23, 24) which connect the pads (2a, 2b; 11a, 11b; 20a, 20b) to each other and to the spinous processes (6, 7), so that, during flexion and extension movements of the spinal column with respect to its normal position, the pressures exerted against the lateral faces of the spinous processes (6, 7) by the pads (2a, 2b; 11a, 11b; 20a, 20b) increase as the spinal column moves away from the normal position. Method for making a pad designed for such a device.
