Sinal de Cecin (Sinal "X"): um aprimoramento no diagnóstico de compressão radicular por hérnias discais lombares

Abstract

Due to the high prevalence, negative repercussions on working capacity, and negative effects on the quality of life, disorders of the lumbar spine represent a challenge in many aspects. Four out of five people will have lumbar pain sometime in their lifetime. Complete history and physical exam are still the diagnostic pillars of those disorders. 1 Imaging diagnostic methods and other tests are just complementary. Approximately 120 diseases affect the lumbar spine. Herniated lumbar disk is one of them. Lumbar pain, lumbosciatalgia, cruralgia, and sciatic pain represent the main symptoms. 2 Lasègue's sign, also called "straight leg raising" in English speaking countries, is the maneuver performed more often to detect mechanical compression and inflammation of lumbar nerve roots by protruding and extruding herniated disks. However, how it should be determined, its mechanism, and the true meaning of its clinical application are still surrounded

Use of Neurodynamic or Orthopedic Tension Tests for the Diagnosis of Lumbar and Lumbosacral Radiculopathies: Study of the Diagnostic Validity

“…However, we do not coincide with other studies that have a similar design [ 40 , 41 , 42 ]. Regarding the safety of the test (predictive values), our results are not in accordance with the values found in other studies [ 43 , 44 , 45 ]. Regarding the lack of external validity of this test, we coincide with other studies that are available in the literature [ 41 , 42 , 46 , 47 ].…”
