Bony pelvis: anatomical positioning and boundaries of the pelvic inlet, pelvic cavity, and pelvic outlet
Pelvic outlet: defining bony structures, orientation, and clinical importance
The pelvic outlet forms the lower boundary of the bony pelvis, playing a crucial role in anatomical positioning, childbirth, and clinical assessments.

Pelvic Outlet: Defining Bony Structures, Orientation, and Clinical Importance
The pelvic outlet, an integral part of the bony pelvis, is formed by distinct anatomical landmarks and serves as a passageway for critical physiological processes.
Anatomical Boundaries of the Pelvic Outlet
- Anterior: The pubic symphysis
- Posterior: The coccyx
- Lateral: The ischial tuberosities and sacrotuberous ligaments
Orientation and Structural Importance
The pelvic outlet is tilted at an angle relative to the pelvis, which facilitates childbirth and structural support. It forms the exit route for the fetus during delivery and significantly impacts obstetric considerations.
Clinical Significance
Pelvic outlet abnormalities can result in obstetric complications, such as cephalopelvic disproportion, necessitating medical interventions such as cesarean delivery. Surgeons often assess pelvic dimensions for trauma recovery and reconstructive surgeries.
