“…In many studies, the subject sample typically exhibits, on average, a shorter duration of symptoms, and we lack data for comparison. This finding would align with studies suggesting that a history of recurrent episodes of low back pain is a risk factor for developing radiculopathy [ 4 , 5 , 60 , 61 ].…”

(1) Background: The diagnosis of lumbosacral radiculopathy involves anamnesis, an assessment of sensitivity and strength, diagnostic imaging—usually magnetic resonance imaging (MRI)—and electrodiagnostic testing (EDX), typically electromyography (EMG), and electroneurography (ENG). MRI evaluates the structures supporting the spinal cord, while EDX evaluates root functionality. The present study aimed to analyze the concordance of MRI and EDX findings in patients with clinically suspected radiculopathy. Additionally, we investigated the comparison between these two reference tests and various clinical variables and questionnaires. (2) Methods: We designed a prospective epidemiological study of consecutive cases with an observational, descriptive, cross-sectional, and double-blind nature following the STROBE guidelines, encompassing 142 patients with clinical suspicion of lumbosacral radiculopathy. (3) Results: Of the sample, 58.5% tested positive for radiculopathy using EDX as the reference test, while 45.8% tested positive using MRI. The comparison between MRI and EDX in the diagnosis of radiculopathy in patients with clinical suspicion was not significant; the overall agreement was 40.8%. Only the years with symptoms were comparatively significant between the positive and negative radiculopathy groups as determined by EDX. (4) Conclusion: The comparison between lumbar radiculopathy diagnoses in patients with clinically suspected pathology using MRI and EDX as diagnostic modalities did not yield statistically significant findings. MRI and EDX are complementary tests assessing different aspects in patients with suspected radiculopathy; degeneration of the structures supporting the spinal cord does not necessarily imply root dysfunction.

“…El pronóstico depende del grado de lesión según la clasificación de Sunderland 5 , en los casos más leves es bueno y la recuperación espontánea es la regla 3 ; su seguimiento será clínico exclusivamente. En las lesiones más importantes hay que esperar al menos tres meses antes de decidir otras medidas más invasivas.…”

“…La causa más frecuente de lesión es la compresión del nervio en la parte posterior del húmero (canal de torsión humeral) presentando en este caso caída de la mano en pronación y semiflexión con pulgar en abducción. En otros casos se puede presentar también paresia de la supinación e hipoestesia en la región de la tabaquera anatómica 3,4 .…”

RESUMENLa denominada "parálisis del sábado noche" se engloba dentro de las neuropatías producidas por compresión de un nervio cuando atraviesa un canal o desfiladero, y en este caso concreto, el afectado es el nervio radial. La causa suele ser el hecho de quedarse dormido con el brazo colgando o comprimido por el peso del cuerpo. Es un cuadro clínico que se manifiesta por imposibilidad para realizar la flexión dorsal de la muñeca y extensión y separación de los dedos. La evolución habitual es hacia la recuperación en 3-6 meses. Presentamos el caso de un varón de 40 años que presenta un cuadro de este tipo por compresión del nervio ínteróseo posterior de intensidad muy severa.Palabras clave: Neuropatías compresivas, "Parálisis del sábado noche". ABSTRACT Saturday night palsySo-called Saturday night palsy falls within neuropathies caused by the compression of a nerve when it passes through a canal or outlet1 and, in this specific case, the radial nerve is affected. The usual cause is having fallen asleep with an arm hanging down or compressed by the weight of the body. It is a clinical picture manifested by the inability to perform wrist dorsiflexion or to extend and separate the fingers. The usual evolution is towards recovery in 3 to 6 months. We report the case of a 40 year old male with this type of picture due to very severe compression of the posterior interosseous nerve. Keywords INTRODUCCIÓNLa denominada "parálisis del sábado noche" se produce por compresión del plexo braquial en una postura que comprometa la funcionalidad del mismo; se puede producir por diversos mecanismos y pueden verse afectadas diferentes ramas nerviosas.El nervio radial es una rama terminal del tronco posterior del plexo braquial. Es un nervio sensitivo-motor implicado fundamentalmente en la extensión del codo, muñeca y dedos y supinación del antebrazo, por lo que el signo más característico de parálisis del nervio radial es "la mano caída" 1,2
