Inferior pubic ramus

Inferior Pubic Ramus

The Inferior Pubic Ramus is a part of the pelvic bone structure in the human body. It is one of the three sections of the pubic bone, the other two being the superior pubic ramus and the pubic body.

Anatomy

The Inferior Pubic Ramus extends from the body of the pubic bone and projects downwards and laterally. It is thin and flat, and its size and shape vary among individuals. It forms a part of the obturator foramen, which is a large opening in the pelvic bone that allows passage of nerves and vessels.

The Inferior Pubic Ramus articulates with the ischium, another bone of the pelvis, at the ischio-pubic ramus. This joint is a type of synchondrosis, which is a cartilaginous joint where the bones are joined by hyaline cartilage.

Function

The Inferior Pubic Ramus serves several important functions in the human body. It provides attachment for several muscles, including the gracilis muscle, adductor muscles, and obturator muscles. These muscles play key roles in movement and stability of the hip joint and lower limb.

In addition, the Inferior Pubic Ramus is involved in weight bearing, helping to distribute the weight of the body in both standing and sitting positions.

Clinical Significance

Fractures of the Inferior Pubic Ramus are relatively common, particularly in older individuals with osteoporosis. These fractures can result from falls or other forms of trauma. Treatment typically involves pain management and physical therapy, although surgery may be required in severe cases.
