Increasing age does not affect good outcome after lumbar disc replacement.

From 1992 to 1998 fifteen Link-Charite SB III disc prostheses were implanted into 14 patients. The main indication was degenerative lumbar disc disease with segmental instability. With a mean follow-up of 48 months (18-68 months); 12 patients had a good (10) or fair (2) outcome regarding pain relief, return to employment and level of general physical activity. In contrast to previous publications we felt that age over 45 years did not appear to adversely affect the outcome.
