In which position does a patient lie on their back with feet in stirrups and knees flexed and separated?

The lithotomy position is characterized by the patient lying on their back with legs supported in stirrups, knees flexed and separated. This position is frequently used in various medical examinations and procedures involving the pelvic region, such as gynecological exams or childbirth. By having the feet in stirrups and the legs elevated, healthcare providers gain better access to the pelvic area, facilitating examinations, surgeries, or other interventions.

In contrast, the other positions mentioned have distinct characteristics that set them apart. For example, the sitting position involves the patient sitting upright, while the prone position requires the patient to lie face down. The supine position, although it involves lying on the back, does not include the stirrups or the specific positioning of the knees and feet as seen in the lithotomy position.
