Day Case Lumbar Fusion Surgery
The article discusses a case of a lumbar synovial cyst located at the same level as a previously inserted spinous process fusion device. Synovial cysts of the spine are degenerative cystic lesions that can cause severe symptoms by compressing the spinal cord, nerve roots, or the cauda equina. While some believe that the development of synovial cysts is related to increased motion and instability at the facet joint, this case demonstrates that a spinal process fusion can still lead to synovial cyst formation due to persistent micromotion in that segment. The findings suggest that the risk of synovial cyst formation may not be eliminated with a spinous process fusion

ABSTRACT
Synovial cysts of the spine are degenerative cystic lesions that can lead to severe symptoms secondary to compression of the spinal cord, individual nerve roots, and/or the cauda equina. Some believe the etiology of this entity is related to increased motion across the facet joint and instability. We report a case of a lumbar synovial cyst located at the same level as a previously inserted spinous process fusion device. This case illustrates that, unlike a transpedicular instrumented fusion where the risk of synovial cyst formation is zero, a spinal process fusion can still lead to synovial cyst formation likely due to persistent micromotion across that segment.
