Abstract
Degenerative lumbar scoliosis (DLS) is becoming more and more common in our aging society. At our hospital, we basically perform transforaminal lumbar interbody fusion for causable intervertebra to remove radicular or cauda equinal symptoms. On the other hand, there are some DLS cases with severe low back pain and progressive loss of coronal balance. Here we report such cases for which we performed posterior instrumentation (long fusion). Among 60 cases who underwent surgical treatment for DLS between 2003 and 2011, three received long fusion. The age of these three cases were above eighty and their mean age was 81.7 years old. The mean Cobb's angle was 36.3 degrees before operation, and it was slightly corrected to 17.3 degrees after operation. Clinical symptoms such as severe low back pain improved after operation and patient satisfaction was generally good.
