Luschka's joints

Luschka's joints (also known as joints of Luschka or uncovertebral joints) are small synovial joints in the neck region of the human body. They are named after the German anatomist Hubert von Luschka, who first described them in the 19th century.

Etymology

The term "Luschka's joints" is named after the German anatomist Hubert von Luschka, who first described these joints in 1858. The term "uncovertebral joints" is derived from the Latin words "unus" (one), "vertebra" (vertebra), and "alis" (pertaining to), referring to the fact that these joints are formed by a single vertebra.

Anatomy

Luschka's joints are located in the cervical spine, between the vertebrae C3 to C7. They are formed by the uncinate processes of the vertebrae below, and the uncus of the vertebrae above. These joints are unique to the cervical spine and are not found in other parts of the vertebral column.

Function

The primary function of Luschka's joints is to guide and limit the movement of the cervical spine. They allow for flexion and extension, as well as limited lateral bending and rotation of the neck. They also play a role in preventing vertebral artery compression during neck movements.

Clinical significance

Abnormalities or degeneration of Luschka's joints can lead to various medical conditions. For example, osteoarthritis of Luschka's joints can cause neck pain and radiculopathy. In addition, herniation of the intervertebral disc can result in compression of the nerve root, leading to symptoms such as pain, numbness, and weakness in the arms.
