Hinge joint

Hinge Joint

A Hinge joint is a type of joint in the human body that allows movement in one direction. It is named for its similarity to the mechanical hinge, a device that connects two objects and allows for a limited angle of rotation between them.

Structure[edit | edit source]

The hinge joint is a simple joint that consists of two bones. One bone has a convex surface, and the other has a concave surface. The convex surface fits into the concave surface, allowing for movement in one plane. This is similar to the way a door hinge allows a door to swing open and closed, but not side to side.

Function[edit | edit source]

The primary function of a hinge joint is to allow for flexion and extension. This means that it allows for movement in one plane, such as bending and straightening. Examples of hinge joints in the human body include the elbow, the knee, and the ankle.

Clinical Significance[edit | edit source]

Because of their limited range of motion, hinge joints are often susceptible to injury. Common injuries include sprains, strains, and dislocations. Treatment for these injuries often involves rest, physical therapy, and in some cases, surgery.
