Musculi intertransversarii cervicis
The intertransversarii are short muscles that run between the transverse processes of neighboring vertebrae. They are present throughout the cervical, thoracic, lumbar, and caudal (tail) regions. Their main actions are small degrees of lateral flexion of individual spinal segments and contribution to proprioceptive feedback. In the neck (intertransversarii cervicis) they help with precise head and neck positioning. In the tail they allow fine side-to-side movements. They work with larger muscles such as the multifidus and longissimus to stabilize and control the spine. Innervation is segmental from the spinal nerves of the corresponding region.
Origin: Transverse process of one cervical vertebra
Insertion: Transverse process of the adjacent cervical vertebra
Action: Lateral flexion of individual cervical segments; proprioceptive stabilization of the neck
Innervation: Ventral branches of cervical spinal nerves (segmental)
Isolated injury is rare. Dysfunction is usually secondary to spinal pain, arthritis, or neurologic disease. Atrophy or asymmetry can be seen with chronic neck or back issues. These muscles are part of the deep stabilizer system.
## Overview Cervical segmental stiffness is reduced motion at one or more individual intervertebral levels rather than generalized neck rigidity. It is commonly linked to facet osteoarthritis, muscle
Stiffness or reduced ability to bend the neck or back one way may involve these deeper stabilizers. Have persistent asymmetry or reluctance to flex evaluated.
## Overview Cervical segmental stiffness is reduced motion at one or more individual intervertebral levels rather than generalized neck rigidity. It is commonly linked to facet osteoarthritis, muscle spasm, or prior injury at that segment and can alter overall neck function and proprioception. ## Causes Local joint disease, multifidus dysfunction, or soft-tissue restriction at a specific level. ## Diagnosis Motion palpation identifies the restricted segment. Imaging correlates structural change when present. ## Treatment Segment-specific mobilization, facet treatment if osteoarthritis is confirmed, and strengthening of local stabilizers. ## Recovery and Prognosis Good with targeted therapy. Underlying degenerative change may require ongoing management. ## Prevention Regular mobility work maintains segmental motion. Signs include: localized restriction of motion; pain on palpation of a specific vertebral level; compensatory stiffness elsewhere
