"Lover's fracture, also known as Don Juan fracture or Casanova fracture, is colloquially used to refer to a type of calcaneal fracture where the mechanism has been a jump from a height 1-3. They are fractures of the calcaneal body and may be intra- or extra-articular 1,2."
"The name "lover's fracture" derives from the situation in which a suitor may jump from a height to escape the lover's spouse 2,3. There is an important association between lover's fractures and burst fractures of the lumbar spine."
