Coccygeal fossa

From WikiMD's Wellness Encyclopedia

Coccygeal Fossa

The coccygeal fossa is a small, shallow depression located in the region of the human body known as the intergluteal cleft, more commonly referred to as the "butt crack". This anatomical feature is situated directly posterior to the coccyx, or tailbone, hence its name.

Anatomy[edit | edit source]

The coccygeal fossa is bordered by the lower part of the gluteus maximus muscle on either side. It is covered by skin and subcutaneous tissue, and does not contain any significant anatomical structures. However, it is in close proximity to the anus and the coccyx, and is therefore relevant in the context of certain medical conditions and procedures.

Clinical Significance[edit | edit source]

The coccygeal fossa is of particular interest in the field of proctology, which deals with disorders of the rectum, anus, and colon. It is also relevant in orthopedics, due to its proximity to the coccyx.

One condition that can affect the coccygeal fossa is a pilonidal cyst, which is a type of skin infection that often contains hair and skin debris. Pilonidal cysts most commonly occur in the coccygeal fossa, and can cause symptoms such as pain, redness, and swelling in the area.

In addition, the coccygeal fossa can be involved in certain surgical procedures. For example, during a coccygectomy, which is the surgical removal of the coccyx, the surgeon may need to make an incision in the skin of the coccygeal fossa.
