Hilton's law
Hilton's law
Hilton's law (/ˈhɪltənz lɔː/), also known as Hilton's principle, is a fundamental concept in anatomy and neurology. The law was first proposed by the British surgeon John Hilton in the 19th century.
Etymology
The term "Hilton's law" is named after John Hilton, who first described the principle in his lectures published as "Rest and Pain" in 1863. The word "law" in this context refers to a rule or principle that describes a natural phenomenon, similar to its usage in the field of physics.
Definition
Hilton's law states that the nerve supplying a joint also supplies both the muscles that move the joint and the skin covering the articular insertion of those muscles. This principle is used to explain the referral of pain from joints to other parts of the body, a common occurrence in conditions such as arthritis and sciatica.
