Rotatores and Multifidi – Functional Anatomy

Multifidi and Rotatores

Multifidi and rotatores form a thick band of muscle that fills the lamina groove. They connect the transverse process of a vertebra to the vertebrae above it. The shortest strand is the deepest. As the strands lengthen to span more vertebrae, they become more superficial.

Rotatores:

Rotatores are the deepest muscle in the lamina groove. Rotatores connect the transverse process of a vertebra to the spinous processes of the two vertebrae just above it.

 Multifidi:

Multifidi lay just on top of the rotatores.  Multifidi connect from the transverse process of a vertebra to the spinous processes of the vertebrae 3-5 segments higher trapping two vertebrae between the attachments.

  

Multifidi attachments vary slightly in different sections or the spine.

Lumbar:

Origin – mamillary process

Insertion – spinous process of the vertebrae 3-5 segments above the origin

Thoracic:

Origin – transverse process

Insertion – the spinous process of the vertebrae 3-5 vertebrae above the origin

Cervical:

Origin – articular process (of the lower four vertebrae)

Insertion – transverse process of the vertebrae 2-4 segments above, up to the axis
