C1-C2 facet joint syndrome is a condition affecting the upper cervical spine, specifically the facet joints between the first (atlas) and second (axis) cervical vertebrae. These joints play a crucial role in neck mobility and stability. When they become inflamed or degenerate, it can lead to significant discomfort and neurological symptoms.
Anatomy of the C1-C2 Facet Joint
Structure and Location
The C1-C2 facet joints, also known as the atlantoaxial joints, are located between the atlas (C1) and the axis (C2) vertebrae. Unlike other spinal joints, the atlas lacks a vertebral body and instead forms a ring that sits atop the axis. The axis features a bony projection called the odontoid process or dens, which protrudes upward into the atlas, allowing for pivotal rotation of the head. Kenhub
Origin and Insertion
These joints originate from the superior articular facets of the axis articulating with the inferior articular facets of the atlas. They are synovial joints, meaning they are enclosed in a capsule filled with lubricating fluid, facilitating smooth movement.
Blood Supply
The vertebral arteries, which ascend through the transverse foramina of the cervical vertebrae, provide blood supply to the C1-C2 region. These arteries are critical as they also supply blood to the brainstem and posterior brain regions.
Nerve Supply
Innervation of the C1-C2 facet joints primarily comes from the medial branches of the dorsal rami of the C2 spinal nerves. These nerves transmit sensory information, including pain signals, from the facet joints to the central nervous system. ResearchGate
Functions
Rotation: The C1-C2 joint allows approximately 50% of the neck’s rotational movement, enabling the head to turn side to side.
Flexion and Extension: It contributes to nodding movements, such as looking up and down.
Stability: Ligaments surrounding the joint, like the transverse ligament, maintain the alignment of the dens within the atlas, ensuring spinal cord protection.Kenhub
Load Transmission: These joints help distribute the weight of the head and absorb shock during movement.
Protection: By maintaining proper alignment, they protect the spinal cord from injury during neck movements.
Facilitation of Movement: They work in concert with other cervical joints to allow a wide range of head and neck motions.
