Intertubercular plane

Intertubercular plane[edit | edit source]

The intertubercular plane, also known as the plane of Ludwig, is an important anatomical reference point used in medical imaging and surgical procedures. It is defined as a horizontal plane that passes through the tubercles of the iliac crests, which are bony prominences located on the upper part of the hip bones.

The intertubercular plane is commonly used to locate and identify structures within the abdomen and pelvis during medical examinations and surgeries. It serves as a reliable landmark for determining the position of organs and structures in relation to the rest of the body.

Anatomically, the intertubercular plane corresponds to the level of the L4-L5 intervertebral disc space, which is located near the lower part of the lumbar spine. This makes it a useful reference point for identifying structures in the lower abdomen and pelvis.

Clinical significance:

In surgical procedures such as laparotomies and abdominal surgeries, the intertubercular plane is used as a guide for making incisions and accessing internal organs.
Radiologists use the intertubercular plane as a reference point for interpreting imaging studies such as CT scans and MRIs of the abdomen and pelvis.
An understanding of the intertubercular plane is essential for accurate localization of structures during medical interventions and diagnostic procedures.

Overall, the intertubercular plane plays a crucial role in clinical practice by providing a standardized reference point for anatomical orientation and localization within the abdomen and pelvis.
