The blockage of the erect muscle fascia (ESP) of the spine is a relatively recent technique that was first described by Forero et al. In September 2016. It has applications in the control of chronic pain with neuropathic component of the thoracic wall, where its original usefulness is born in metastatic rib disease and a defective bonding pathology of multiple coastal fractures. Recent anatomical and radiological research into corpses indicates that the likely site of action for such blockage is in the dorsal and ventral branch of the thoracic spinal nerves. The erecting muscle of the spine is also called sacrospinal and in some texts as a muscular strainer of the spine. ESP is a set of muscles and tendons that extend throughout the entire spine, arises from the anterior surface in the medial portion of the sacrum, at the lumbar level of the spiny apophysis and the thoracic vertebrae 11va and 12va In the lumbar region the erecting muscle of the spine is divided, into three portions: Lateral (muscle Iliocostal), Intermediate (long muscle), Medial (spinal thoracic muscle). In the original description of Doctor Foreo et al. The results were documented with a complete resolution of bone neuropathic pain. ESP blocking is a promise to become a safe, less invasive and useful alternative to clinical application in various pain scenarios.
