![]() ![]() Īs with most nonspecific mechanical disorders of the cervical and lumbar regions, the natural history of the majority of patients with nonspecific thoracic strain or sprain is resolution within 1 to 6 months. Other structures that may lead to strain or sprain in the mid back due to the same inflammatory rationale are the thoracic facet joints and the nerve roots. Muscles adjacent to the injured disc tend to become tight in response to the local inflammatory process, which may jeopardize the local muscle equilibrium, possibly leading to ligament strains and muscle sprains in the thoracic region. Thoracic strain or sprain may be the indirect result of disc lesions, which have been reported to be evenly distributed in incidence between the sexes and are most common in patients from the fourth to sixth decades of life. Moreover, pain felt in the thoracic spine is often referred from the cervical spine, mistakenly giving the impression that the incidence is higher. Therefore observation and characterization of such lesions are minimal, subsequently limiting the potential to improve treatment methods for thoracic sprain and strain disorders. The lifetime prevalence in the general population of having a musculoskeletal complaint in the thoracic spine is 17% in contrast to 57% in the low back and 40% in the neck. EpidemiologyĪlthough the scientific literature on musculoskeletal pain in the cervical and lumbar spine is abundant, similar information about the thoracic region is sparse because of its lower prevalence. Because the thoracic cage is unified by the overlying fascia, thoracic sprain or strain can translate into pain throughout the thoracic spine. Sprain relates to injury in ligament fibers without total rupture, whereas strain is an overstretching or overexertion of some part of the musculature. Thoracic strain or sprain refers to the acute or subacute onset of pain in the region of the thoracic spine due to soft tissue injury, including muscles, ligaments, tendons, and fascia, of an otherwise normal back.
