Camptocormia, also known as bent spine syndrome (BSS), is a symptom of a multitude of diseases that is most commonly seen in the elderly. It is identified by an abnormal thoracolumbar spinal flexion, which is a forward bending of the lower joints of the spine, occurring in a standing position. In order to be classified as BSS, the anterior flexion (the lower back bending) must be of 45 degrees anteriorly. This classification differentiates it from a similar syndrome known as kyphosis. Although camptocormia is a symptom of many diseases, there are two common origins: neurological and muscular. Camptocormia is treated by alleviating the underlying condition causing it through therapeutic measures or lifestyle changes. History and society
Camptocormia comes from two Greek words, meaning "to bend" (κάμπτω, kamptō) and "trunk" (κόρμος, kormos), and was coined by Alexandre-Achille Souques and B. Rosanoff-Saloff. These two men also created the definition of the disease that is widely accepted today.When the disorder was first clinically studied around the time of First World War, it was believed to be a psychogenic conversion disorder that resulted from the severe trauma of war. Souques and others treated patients with psychological therapy and early versions of electrotherapy. Samuel A. Sandler used a similar approach to treat soldiers during the Second World War. The view of BSS as a conversion disorder led to a lack of awareness about the conditions and few diagnoses by physicians. As time progressed and advances were made in knowledge of neuroscience and physiology, biological mechanisms behind the irregular bending were identified.
A hamartoma is a mostly benign, local malformation of cells that resembles a neoplasm of local tissue but is usually due to an overgrowth of multiple aberrant cells, with a basis in a systemic genetic condition, rather than a growth descended from a single mutated cell (monoclonality), as would typically define a benign neoplasm/tumor. Despite this, many hamartomas are found to have clonal chromosomal aberrations that are acquired through somatic mutations, and on this basis the term hamartoma is sometimes considered synonymous with neoplasm. Hamartomas are by definition benign, slow-growing or self-limiting, though the underlying condition may still predispose the individual towards malignancies. Hamartomas are usually caused by a genetic syndrome that affects the development cycle of all or at least multiple cells. Many of these conditions are classified as overgrowth syndromes or cancer syndromes. Hamartomas occur in many different parts of the body and are most often asymptomatic incidentalomas (undetected until they are found incidentally on an imaging study obtained for another reason). Additionally, the definition of hamartoma versus benign neoplasm is often unclear, since both lesions can be clonal. Lesions such as adenomas, developmental cysts, hemangiomas, lymphangiomas and rhabdomyomas within the kidneys, lungs or pancreas are interpreted by some experts as hamartomas while others consider them true neoplasms. Moreover, even though hamartomas show a benign histology, there is a risk of some rare but life-threatening complications such as those found in neurofibromatosis type I and tuberous sclerosis.It is different from choristoma, a closely related form of heterotopia.
