In medicine, prolapse is a condition in which organs fall down or slip out of place. It is used for organs protruding through the vagina, rectum, or for the misalignment of the valves of the heart. A spinal disc herniation is also sometimes called "disc prolapse". Prolapse means "to fall out of place", from the Latin prolabi meaning "to fall out". Relating to the uterus, prolapse condition results in an inferior extension of the organ into the vagina, caused by weakened pelvic muscles. Humans
Heart valve prolapse
The main type of prolapse of heart valves in humans is mitral valve prolapse (MVP), which is a valvular heart disease characterized by the displacement of an abnormally thickened mitral valve leaflet into the left atrium during systole. Tricuspid valve prolapse can cause tricuspid regurgitation. Rectal prolapse
Rectal prolapse is a condition in which part of the wall or the entire wall of the rectum falls out of place. Rectal prolapse can be a medical emergency. In some cases, the rectum may protrude. Symptoms of a rectal prolapse may be:

Leakage of stool
Bleeding, anal pain, itching, irritation
Tissue that protrudes from the rectumA surgeon may operate through the abdomen to secure part of the large intestine or rectum to the inside of the abdominal cavity (rectopexy). Sometimes the surgeon removes the affected part of the intestine. Surgery also can be done through the perineum (the area between the genitals and the anus) to remove the prolapsing tissue. Surgery is most often successful for people who still have some control over their bowel movements.
Hallux varus is a deformity of the great toe joint where the hallux (great toe) is deviated medially (towards the midline of the body) away from the first metatarsal bone. The hallux usually moves in the transverse plane. Unlike hallux valgus, also known as hallux abducto valgus or bunion, hallux varus is uncommon in the West but it is common in cultures where the population remains unshod. Photos
