VEGA SARRAULTE, Gabriela. Síndrome regional complejo: revisión bibliográfica. Med. leg. Costa Rica [online]. 2015, vol.32, n.2, pp.51-63. ISSN 2215-5287.

The complex regional pain syndrome is a clinical entity that is difficult to diagnose, especially when you are not familiar with the term. In order to identify it, it is necessary to know it well. It produces spontaneous pain like hyperalgesia and allodinya causing sensory distorted phenomena, variations of blood flow, sweating, and trophic changes by a localized inflammatory condition, followed by a stage of chronic neuropathic disorders. Its presence is most often related to an unspecified trauma or direct damage to a nerve structure in the extremities. Generally, it is divided in two forms: type I, formerly known as reflex sympathethic dystrophy, and type II, better known as causalgia. Though it has not been possible to establish its pathophysiology, it is recognized that the entire nervous system is involved. In daily practice, a Costa Rican forensic doctor is presented with the assessment of bodily harm in the fields of work accidents, criminal agressions, and administrative litigation. Since there are cases in which this syndrome may be directly related, it is extremely important to learn how to identify it successfully.

Keywords : complex regional pain syndrome; hyperalgesia; allodinya; legal medicine.
