[Clinical characteristics of reflex sympathetic dystrophy in Aragon (Spain). A prospective study of 171 patients]. / Estudio descriptivo y prospectivo de 171 pacientes con distrofia simpático refleja en Aragón (España).

We followed a total of 171 patients diagnosed with Reflex Sympathetic Dystrophy (RSD). This enigmatic condition normally has a secondary origin, being trauma the unleashing cause in most cases. Psychological predisposition plays a major role in developing the clinical state, which affects lower extremities more frequently. In this series, patients were first seen during the acute "warm" phase and the final outcome was generally good after a period of treatment with non-steroidal anti-inflammatory drugs (NSAID), calcitonin and physical therapy. However, a comprehensive review of the literature revealed the heterogeneity of this condition.
