Bäckenhålan

Bäckenhålan, also known as the ischial tuberosity, is a bony prominence located on the posterior aspect of the ischium, the lower and posterior part of the pelvis. It is a significant landmark in anatomy, particularly in the context of pelvic and perineal examinations. The term "Bäckenhålan" is derived from Swedish, where "bäcken" means pelvis and "hålan" means hole or cavity.

The ischial tuberosity is a rough, triangular area that serves as an attachment point for several muscles, including the gluteus maximus and the piriformis. It is also a key reference point for measuring the pelvic inlet and outlet, which are important in the assessment of pelvic disorders and in surgical procedures.

In clinical settings, the ischial tuberosity is often used as a landmark for examining the pelvic floor and the perineum. It is also relevant in obstetrics, where it is used to assess the position of the fetus during labor.

The ischial tuberosity is a part of the ischial spine, which extends from the ischial tuberosity to the ischial tuberosity of the opposite side. The ischial spine is a crucial structure in the support of the pelvic organs and the transmission of forces during activities such as walking and running.

In summary, the ischial tuberosity, or Bäckenhålan, is a prominent bony landmark on the posterior aspect of the ischium, with significant clinical and anatomical importance. Its role in muscle attachment, pelvic measurements, and clinical examinations makes it a key structure in the study of the pelvis and perineum.
