Cerebrospinal fluid (CSF) leak after Fracture of the Sacrum or Coccyx.

Here is a recent publication by Dr. Foye.

Cerebrospinal fluid (CSF) leak after Fracture of the Sacrum or Coccyx.
  • Dr. Foye’s Summary:
    • Leakage of Cerebrospinal fluid (CSF) is much more commonly expected after fracture of the sacrum, rather than after fracture of the coccyx (tailbone).
    • The reason is that the anatomy of the sacrum contains the spinal canal, which contains CSF.
    • Meanwhile, the anatomy of the coccyx bones do NOT include any spinal canal, and thus the coccyx does not have any CSF.
    • Leakage of CSF after a fracture limited to only the coccyx would mainly only happen if the trauma caused substantial pulling onto the filum terminale (fibrous tissue that extends from the lower tip of the spinal cord to its attachment on the upper coccyx).
