Sacral dimples may indicate conditions such as spina bifida. This condition occurs when the spine doesn’t form properly in a fetus. Generally, the spine fails to enclose the spinal cord fully. Another condition at which sacral dimples may hint is tethered cord syndrome. Normally, the spinal cord hangs freely within the spinal canal. However, in tethered cord syndrome, the spinal cord attaches to tissue, inhibiting its movement. This can cause numbness, bladder issues, or weakness.
