RELLAN, Ignacio et al. Doble compresión del nervio mediano en el brazo: Revisión crítica de la bibliografía. Rev. Asoc. Argent. Ortop. Traumatol. [online]. 2019, vol.84, n.4, pp.427-433. ISSN 1852-7434.

Double crush syndrome is the mechanical compression of a peripheral nerve at two different sites and is based on the hypothesis that a nerve that has been compressed at a distal site is especially susceptible to also be compressed, asymptomatically, at a more proximal site. While carpal tunnel release is a surgical procedure with predictable results, some patients do not improve as expected after surgery. If comorbidities such as diabetes, advanced cases presenting with muscle atrophy or incomplete decompressions are excluded from the analysis, many of these treatment failures could be explained by a second concomitant compression site, which is often underdiagnosed. The very existence of double crush syndrome is highly questioned, but also its incidence and pathophysiology. The objective of our paper is to perform a critical review of the literature available on double crush syndrome involving mainly the median nerve in the wrist and the elbow.
