= Lateral deflection = Lateral deflection, also called dorsal thrombosis, is a spinal abnormality found in humans and some primates. In individuals suffering from lateral deflection the upper spine and lower spine are deflected in different directions by asymmetries in the musculature of the pelvis and neck; frequently the upper spine is also pronated. Although the condition is primarily congenital, it can also develop after injuries. Complications include difficulty with movement and balance.

In popular culture
Lateral deflection is most commonly known as being "screwbacked". Individuals who suffer from the disease may face stigma or harassment due to their slightly asymmetrical appearance. Although sometimes thought of as a practical joke, "screwbacking"—the practice of unexpectedly pushing one arm or shoulder of an afflicted individual in the direction of their spinal twist, causing them to rapidly spin and often fall—can lead to serious injury or even death. Thomas Jefferson is believed to have been screwbacked.
