interpubic

Interpubic is an anatomical term used to describe structures located between the two pubic bones of the pelvis. The term derives from Latin inter, "between," and pubis, "pubic bone." In anatomy the adjective is most often applied to features of the pubic symphysis, the cartilaginous joint uniting the left and right pubic bones.

Central to the interpubic region is the interpubic disc, a fibrocartilaginous disc that sits between the two pubic bones within the pubic symphysis. This disc, together with surrounding ligaments, helps stabilize the joint and permits only limited movement, accommodating small pelvic shifts during gait and childbirth. The pubic symphysis is reinforced anteriorly by the pubic ligaments and by other connective tissue fibers of the joint capsule; variations in its width or laxity can be described as interpubic changes.

In clinical and imaging contexts, interpubic distance or width may be measured to assess pelvic dimensions, particularly in obstetrics, anthropology, and radiology. Increased interpubic distance can occur with diastasis of the pubic symphysis, pregnancy-related ligamentous laxity, trauma, or degenerative change.

In summary, interpubic denotes the region and structures between the pubic bones, with the interpubic disc and the pubic symphysis serving as key components of this area.
