The pelvis is the largest integrated bone structure in the body. This important structure divides the force of gravity of the trunk between the two lower limbs.

The pelvis contains important digestive, reproductive, and urinary organs, and important arteries and nerves pass through it to the lower extremities.

Pelvic pain and changes in the shape of its skeletal structure and injuries that can result from severe trauma are among the most important reasons for patients to see a doctor because of pelvic problems.
