Multifidus

Multifidus

The Multifidus muscle is one of the smallest yet most "powerful" muscles that gives support to the spine. It spans three joint segments, and works to stabilize these joints at each level. The stiffness and stability makes each vertebra work more effectively, and reduces the degeneration of the joint structures. These small muscles are very important in the management of back pain.

Anatomy

The Multifidus muscle is a series of muscles attached to the spinal column. These are located in the lumbar region, thoracic region, and cervical region. The muscle is deep and spans three joint segments. It is attached to the vertebrae of the spine.

Function

The Multifidus muscle has several important functions. It controls the tension and stiffness in the joints of the spine, and also controls the motion of the spine. The muscle is also responsible for the stability of the spine, and helps to prevent degeneration of the joint structures.

Clinical significance

The Multifidus muscle is often implicated in cases of back pain. It is thought that the muscle's ability to stabilize the spine is compromised in these cases. This can lead to increased pressure on the vertebrae and discs, leading to pain.
