Pubic bone


STRUCTURE AND POSITION

●       Pubis is present on anterior aspect of the Pelvis in relation with other 2 bones (Ilium and Ischium). It is covered by fat and skin.

●       Pubis is further divided into three parts.

  • Body of the Pubis is the thick, main part present anteriorly. It branches posterolaterally into two Rami.

  • Inferior Ramus is inferior projection from the Body of the Pubis. It is joined to the Ischium.

  • Superior Ramus is the superior projection of the Pubis and joins with the Ilium and Ischium.

●       Pubis forms least part of the Acetabulum laterally (one fifth). Acetabulum is a circular structure formed by the bones of the Pelvis laterally which accommodates the head of the Femur.

ARTICULATIONS

  • Each Pubic bone articulates anteriorly with the other on opposite side in centre. Their Bodies are joined by a FibroCartilaginous (made up of strong cartilage and fibers) joint. It is called Pubic Symphysis situated just under the skin of Mons Pubis.
  • Pubis also articulates with the Head of the Femur through Acetabulum.
