There are 2 types of CRPS: type I previously called reflex sympathetic dystrophy which is characterized because the trauma spares the nerves, like in sprains, some fractures, surgical trauma, some contusions or distentions; and type II previously called causalgia, usually developed after an injury that involves a peripheral nerve 1.
Existen dos tipos de SDRC: el tipo I, llamado anteriormente distrofia simpática refleja, caracterizado porque el trauma no afecta los nervios, como sucede en esguinces, algunas fracturas, trauma quirúrgico, contusiones o distensiones; el tipo II, antes llamado causalgia, se desencadena después de una lesión que compromete un nervio periférico 1.
