SURGICAL IMPLANT

摘要

A prosthesis for the replacement of an intervertebral disc of the spine comprises a block (6) of an elastomeric material, which is held under compression by an encapsulating textile fabric (2). A preferred version of the invention has continuations (74, 76) of the encapsulating fabric (56) forming an interdigitation, with the continuation (74) of the upper fabric (72) passing through a hole (80) in the lower fabric and being attached to the lower vertebral body (22) and the continuation (76) of the lower fabric crossing to its fixation site on the upper vertebral body (20).
