Abstract (English): Introduction: Carpal tunnel syndrome is the most frequent peripheral neuropathy and it affects nearly 3% of the general population. Although electromyography tests have become the gold standard for diagnosis, currently there is controversy between the correlation of clinical data and electromyography for diagnosis. The purpose of this work is to study this correlation and determine the possible prognostic factors in this pathology. Material and methods: 139 patients who underwent surgery were reviewed retrospectively between January 1995 and December 2008. All patients had an electromyography preoperatively to obtain motor conduction rate and latency, sensitive conduction rate and clinical examination, especially the Tinel and Phalen signs in order to correlate them with the final postoperative symptoms. In order to establish if there were statistically significant differences, these were determined through the T-Student and x2- Results: Preoperatively, there is a clinical correlation (p < 0.05) between the Tinel and Phanel clinical signs with the compression electrophysiological grading. Likewise, there is a correlation between clinical persistence in the postoperative period with motor conduction rate and latency involvement specified in the preoperative electrophysiological tests. Conclusion: Electrophysiological tests in the diagnosis of carpal tunnel syndrome have an added prognostic value with regards to the final result after surgery. [ABSTRACT FROM AUTHOR]
Abstract (Spanish): Introducción: El síndrome del túnel carpiano es la neuropatía periférica más frecuente y afecta casi al 3% de la población general. Aunque los estudios electromiográficos se han convertido en el patrón oro para diagnóstico, en la actualidad existe controversia entre la correlación de los datos clínicos y electromiografía para su diagnóstico. Este trabajo tiene como objetivo el estudio de esta correlación, y determinar los posibles factores pronósticos en esta patología. Material y métodos: Se revisaron retrospectivamente a 139 pacientes intervenidos quirúrgicamente entre Enero de 1995 y Diciembre de 2008. A todos se les realizó preoperatoriamente un estudio electromiográfico donde se recogió latencia y velocidad de conducción motoras, velocidad de conducción sensitiva y exploración clínica, en especial los signos de Tinel y Phalen, con el fin de correlacionarlos con la sintomatología postoperatoria final. Para establecer si hubo o no diferencias estadísticamente significativas se determinaron mediante la T-Student y %z. Resultados: Preoperatoriamente existe una correlación clínica (p < 0.05) entre los signos clínicos de Tinel y Phalen con el grado electrofisiológico de compresión. Igualmente, existe correlación entre la persistencia de la clínica en el postoperatorio con la afectación de la latencia y velocidad de conducción motora objetivada en los estudios electrofisiológicos preoperatorios. Conclusión: Los estudios electrofisiológicos en el diagnóstico del síndrome del túnel carpiano poseen un valor añadido pronóstico con respecto al resultado final tras la cirugía.
