At one stage the os coccyx projects like a true tail, extending considerably beyond the rudimentary legs.
Mobility of the skin might be more pronounced at the ventral side of the patient than above the spine or coccyx.
That does not include the lower sacrum and the coccyx.
The x-rays were taken and a possible fracture to the coccyx was diagnosed.
In some cases, persistent pressure from activities like bicycling may cause the onset of coccyx pain.
The pubococcygeus, the main part of the levator, runs backward from the body of the pubis toward the coccyx and may be damaged during parturition.
It pierces the sacrotuberous ligament to supply the skin in the region of the coccyx as well as the sacrococcygeal joint.
A simple test to determine whether the coccyx is involved is injection of local anesthetic into the area.
