During a vaginal hysterectomy, which nerve is at risk for injury due to inappropriate placement of retractors?

During a vaginal hysterectomy, the deep femoral nerve is at risk for injury if retractors are not placed appropriately. This nerve, which is a branch of the femoral nerve, is responsible for innervating the muscles of the anterior compartment of the thigh and providing sensation to part of the thigh. Inadequate positioning of retractors during the surgical procedure can lead to direct pressure or trauma to surrounding tissues, including nerves situated in the area.

The other nerves listed, such as the superficial peroneal nerve, tibial nerve, and common fibular nerve, are primarily associated with the lower leg and foot. They do not typically come into contact with the surgical field during a vaginal hysterectomy and therefore are less likely to be affected by the intrapelvic retractions that are more directly associated with the anatomy of the vaginal canal and pelvic floor. Understanding the anatomy and the trajectory of these nerves during surgical procedures is crucial to avoid any iatrogenic injuries.
