Rotary subluxation, also known as atlantoaxial rotatory subluxation (AARS), is a condition where there is an abnormal rotational alignment between the first (atlas) and second (axis) cervical vertebrae.
This condition primarily affects the cervical spine, particularly the neck region.
It can lead to symptoms such as neck pain, reduced range of motion, and noticeable head tilting or rotation.
Rotary subluxation is more frequently observed in children due to the increased laxity of their ligaments and the relatively large size of their head compared to their body.
Causes may include trauma, infection, or inflammatory conditions.
The condition can be acute or chronic, with acute cases often resulting from sudden movements or trauma.
Diagnosis typically involves imaging studies, such as X-rays, CT scans, or MRI, which can reveal the misalignment and help assess the extent of the subluxation.
Treatment depends on the severity and duration of the condition, ranging from conservative management with physical therapy and immobilization to more invasive procedures such as traction or surgery in severe cases.
Early recognition and appropriate management of rotary subluxation are crucial to prevent potential neurological complications and to restore normal alignment and function of the cervical spine.
