A clinical patient with a funnel-shaped pelvis is a patient who has a normal pelvic entrance plane with normal diameter values, but a narrower position in the mid-pelvis and exit plane, and a funnel-shaped pelvis with both sides tilted medially. The cause of the funnel-shaped pelvis is mainly due to rickets during childhood or due to softening of the patient’s bones, which deforms the pelvis. A funnel pelvis can be caused by poliomyelitis, tuberculosis of the spine and hip area, or trauma. Because the funnel pelvis is not easily detectable, it is mostly detected during prenatal checkups before delivery.
