Spinal attachment for damping movements of adjacent vertebrae, comprises two cushions with inner surfaces held against surfaces of spiny processes

摘要

The attachment consists of two cushions (2a, 2b) with their inner surfaces applied against the lateral faces of the spiny processes (6, 7) on two adjacent vertebrae (8, 9), to which they are attached by ligaments (5a, 5b, 5c, 5d). . The attachment consists of two cushions (2a, 2b) with their inner surfaces applied against the lateral faces of the spiny processes (6, 7) on two adjacent vertebrae (8, 9), to which they are attached by ligaments (5a, 5b, 5c, 5d). The cushions can be made from folded and stitched strips or whole blocks of material in an approximately hemispherical or hemi-ovoid shape, and can have inner surface projections that fit in the gap between the spiny processes. In variants of the design the cushions can be fixed in place by extra ligaments or a transverse pin passing through them.
