LECAROS L, Miguel Ángel et al. TRAUMATIC LUMBAR NERVE ROOT AVULSION. Rev. chil. radiol. [online]. 2008, vol.14, n.1, pp. 36-38. ISSN 0717-9308.  doi: 10.4067/S0717-93082008000100008.

Traumatic lumbosacral nerve root avulsion it's an infrequent injury that appears in association with pelvic and lumbar fractures or hip dislocations. We describe a clinical case of traumatic avulsion at the LI lumbar root in a patient victim of an accident of high energy, without associate injuries. Magnetic resonance demonstrated traumatic pseudomenin-gocele at the LI lumbar root. The use of intrathecal gadolinium allowed us to confirm diagnosis and evaluate extension. Seven months later, patient returns to its labour activities with minimum pain
