Contusion coccyx

The coccyx bruise is one of the most common and painful injuries a person can suffer. Older people and athletes in particular are often affected by a coccyx contusion or even a coccyx fracture (fracture) or luxation (dislocation). Located at the lower end of the spine, the coccyx, also known as Os coccygis, is responsible for numerous movements.

After a coccyx contusion, however, simple activities such as walking and, above all, sitting are suddenly no longer possible or can only be carried out with very severe pain. A coccygeal contusion is usually medically classified as harmless, but can be a real test of patience for patients due to the severe pain and the immense restriction of movement. Severe pain and resulting insomnia are common symptoms. In severe cases, it may even be necessary to take a sick leave for several weeks due to inability to work.

Anatomy

The coccyx, also called Os coccygis, is part of the lower spine of the human body. It is bony and connected to the sacrum (Os sacrum) above. It forms a synostosis with the sacrum, i.e. a bony connection between two structures.

The coccyx itself consists of 5 originally created vertebrae, which in most people have grown together to form a single bone. It can be considered a rudimentary remnant of the tail of vertebrates. In general, the coccyx is the starting point for many muscles and ligaments, which are mainly necessary for sitting, walking and bending movements.

If these muscles fail or can only be used partially due to excessive pain, many elementary movements such as getting up or walking upright are no longer possible. Due to its position, the coccyx is well protected from everyday stress, but it can be severely affected by falls and lead to painful bruises. In severe and rather rare cases, fractures (coccyx fractures) or dislocations (coccyx luxations) can also occur.

Coccyx dislocations in particular often lead to difficulties in walking and must be treated surgically to prevent future damage such as arthrosis. Coccyx fractures can usually also be treated conservatively with immobilization and painkillers. Only rarely is surgery necessary. Typical here is the development of a large hematoma on the buttocks and abnormal mobility of the coccyx vertebrae.
