cardinal ligament
Primary supportive ligament extending from the cervix and upper vagina to the pelvic sidewall. Critical anatomical landmark in radical hysterectomy procedures.
Full Definition
The cardinal ligament, also known as the transverse cervical ligament or Mackenrodt ligament, is a major supportive structure of the uterus that extends laterally from the cervix and upper third of the vagina to the fascia over the internal iliac vessels. It contains the uterine vessels and provides crucial support to the uterovaginal complex. During radical hysterectomy, careful dissection of this ligament is essential to avoid injury to the ureter, which passes beneath it. The ligament's integrity is also important in procedures addressing uterine prolapse.
Usage
Usage note: Often confused with other pelvic support ligaments; specify anatomical relationships clearly.
