Este proceso es lento y complejo, haciendo difícil su detección en el análisis estadístico. ANTECEDENTES: Un estudio anatómico publicado recientemente en la revista “American Journal of Sports Medicine” por Alpert, J.M., et al., (2010), identificaba por primera vez en la historia la anatomía de sección cruzada del conjunto de músculos conocido como psoas-ilíaco al nivel del labrum acetabular. Un músculo psoas-ilíaco tirante o acortado puede ser causa de un aumento en la presión intra-articular así como de un síndrome de degeneración de la cadera,
